10 Best Orthopedic Dog Beds for Senior Dogs (October 2026) Reviews

A senior dog sleeps 12 to 16 hours a day, and roughly 60% of dogs over the age of 10 show signs of arthritis. That combination is why the sleeping surface matters more than almost any other thing you can buy for an aging dog, and it is why we spent the last two months putting ten of the best orthopedic dog beds for senior dogs through real comparison.

We screened more than two dozen beds sold in the category, then narrowed the list using the numbers that actually decide whether foam helps a stiff hip: thickness in inches, foam density, whether the cover unzips for a machine wash, and whether there is a waterproof liner between the sleeping surface and the foam. We also weighed review volume, because a bed that flattens in four months is a bed you buy twice.

Everything below is ranked, and every pick carries an explicit choose-if and skip-if rule so you can tell quickly whether a bed fits your dog or is just another expensive rectangle on the floor. If your dog has just had ligament surgery, jump to pick 10. If incontinence is the problem, start at pick 2.

Top 3 Picks for Senior Dog Beds in 2026

Best Orthopedic Dog Beds at a Glance in 2026

What Is an Orthopedic Dog Bed?

An orthopedic dog bed is a raised mattress built from dense memory foam or egg-crate foam that spreads a dog’s weight across a wider area instead of letting the hips, elbows and shoulders sink to the floor. That wider spread is what reduces pressure on arthritic joints.

The dense foam resists compression under body weight, so the surface stays level and the spine stays aligned. A level surface is the entire point. A cheap bed padded with thin polyfill looks thick in photos but bottoms out under a 70-pound dog within months, and a bottomed-out bed is no better than a folded quilt on a hard floor.

Three terms decide whether a bed is genuinely orthopedic. Loft is the thickness in inches. Density is how much foam is packed into a cubic foot, and anything under 3 pounds per cubic foot is soft filler rather than support foam. Egg-crate foam is the bumpy layer that spreads pressure in a grid pattern. A good senior bed combines a dense base with enough loft that your dog does not reach the floor.

1. JOYELF XLarge Memory Foam Bed Is the Best Overall Pick for Senior Dogs

This is the bed we keep coming back to because it is the rare one where the review themes are boring in the best way. Owners of large breeds, huskies and multi-dog households describe the same outcome: the base holds its shape, the cover survives washing, and the bolsters get used as a headrest every single night.

The XLarge version measures 40 by 30 by 9 inches overall, with a sleeping area inside the bolster of 32 by 22 inches and a 37.5 by 25.5 inch memory foam base. The company rates it for dogs up to 100 pounds, and there are variants from 27 by 20 inches up to 47 by 33 inches so the footprint can be matched to a smaller senior.

Our screening looked specifically for the failure modes that hit senior dogs, and this bed handles two of the three well. The internal waterproof liner sits between the fleece surface and the foam, which means an overnight accident wipes out instead of soaking in. The built-in nonslip rubber backing keeps the whole bed planted on tile or laminate when a stiff dog tries to stand up.

The honest weakness is the liner itself. A minority of owners report the inner liner cracking and peeling after roughly a year of use, and that complaint clusters among dogs that are incontinent often enough to expose it. Bolster corners also lose some shape over time, and the base reads as under-firm to dogs who like a softer surface. None of that is disqualifying, but if your dog is small and prefers plush, look at pick 6 instead.

Choose this bed if your dog weighs more than 50 pounds

The 100-pound rating and the solid foam base make this the safest all-round answer for a large senior with morning stiffness. If your dog stretches out flat and you can measure a stretched-out length, the 40 by 30 footprint gives enough room to actually load the supportive core rather than perching on the edge.

It also suits multi-dog households, since two dogs can share the wider bolster ring without one pushing the other off the edge.

Skip this bed if your dog is a heavy chewer or needs a very low entry

The cover is plush, not chew-resistant, and a dog that works at fabric will find the zipper. The bolster ring also raises the entry point, which is a problem for a dog with weak hind legs that cannot step up and over rather than onto.

If climbing on is the issue, pick 9 has a lowered entrance, and pick 4 has an open lounger shape with no raised ring at all.

2. EHEYCIGA Waterproof XL Couch Is the Best Value Pick for Incontinent Senior Dogs

If your dog has urinary accidents, this is the bed we would buy first. The waterproof film sits between the fleece sleeping surface and the bottom fabric, so liquid never reaches the foam, and that is the difference between a wipe-down and a ruined bed.

The XL measures 44 by 32 by 6 inches and the range runs from 24 by 18 up to 52 by 41 inches across more than 100 color and size combinations. That sizing spread matters for senior dogs, because a correctly sized footprint is the thing that stops a dog from sliding off the edge and never loading the foam underneath.

Owners of senior dogs including a 9-year-old maltipoo describe the fleece surface as soft and the three-sided bolster as a headrest their dog leans into. Reviewers consistently single out the waterproofing and the washability, which is exactly what an incontinent dog needs from a bed.

Two caveats. A few buyers dispute the orthopedic positioning and describe the fill as essentially egg crate, and some say the foam reads thinner in person than in the listing photos. Allow 24 to 48 hours for the bed to reach full shape after unpacking, and remember that the foam insert itself is not washable, only the cover.

Choose this bed if accidents are the main problem

The waterproof film is the deciding feature here, and no amount of extra bedding reproduces it. If you are wiping down a bed every morning or replacing bedding weekly, this is the pick that ends that routine.

It is also a sensible second bed. A waterproof orthopedic bed in the bedroom plus a washable one by the door covers the whole day.

Skip this bed if your dog needs serious joint loft

The XL is 6 inches tall overall, but that measurement includes the bolster, so the flat sleeping surface is closer to 3 inches. For a large dog with confirmed hip dysplasia, a deeper dedicated core like pick 5 or pick 10 will hold its shape better under load.

If your dog chews fabric, the faux linen sides are not a good match either.

3. Comfort Expression Waterproof XL Bed Is Built for Big Dogs on a Budget

The XL version gives you a 42 by 30 inch footprint with a 34 by 26 inch sleeping area, a 3.5 inch flat base and 5 inch bolsters, rated for dogs up to 32 inches long and 90 pounds. That is a real size for a large senior, and the CertiPUR-US certified egg crate base is the honest orthopedic component.

Reviewers describe this as a clear step up from cheaper beds rather than a premium purchase, which is exactly the right framing. The foam keeps its loft over time in most accounts, the cover comes fully off for washing, and the non-slip bottom holds on tile where many beds slide.

The number to read carefully is 5 inches. That is the bolster height, not the base. The flat sleeping area is 3.5 inches, which is fine for a dog up to about 50 pounds and marginal for a 90-pound dog whose hips carry most of the load. Owners do report it holding shape, but a very large dog on a 3.5 inch base will feel the floor eventually.

The OEKO-TEX Standard 100 certified fabric is a nice detail for a bed that sits in a bedroom. Assembly takes a few minutes because the base and bolsters are inserted separately, and the bed is vacuum packed, so give it up to 48 hours to reach full loft.

Choose this bed if you want a certified foam base at a mid-range price

CertiPUR-US certification on the foam is the differentiator here, and it matters more than most buyers realise. It confirms the foam was tested for harmful emissions and chemicals, which is a reasonable standard of proof for a surface your dog lies on for half the day.

Pick it when your dog is between about 50 and 90 pounds and you want a waterproof liner without paying for a thick memory foam core.

Skip this bed if bolster height is what you are buying

Several buyers note that the bolsters feel under-filled as headrests, which matters if your dog sleeps with its chin propped up. If head and neck support is the priority, pick 5 with its dual pillows or pick 10 with its integrated headrest will serve better.

There are also scattered reports of inconsistent stitching and a foam insert that stayed compressed, so check the base on arrival.

4. FurHaven Luxe Lounger Is the Best Bed for Dogs That Stretch Out

This is the one to look at if your dog sleeps on its side with all four legs stretched out. It is an open lounger rather than a bolstered couch, so the bolstered edges act as a headrest without walling the dog in, and long-standing owners report a decade of use out of earlier sizes.

The distinguishing construction detail is a solid high-density orthopedic foam slab instead of egg-crate foam. A slab keeps a level surface under a heavy dog, which is exactly what an arthritic hip needs. The Jumbo XL measures 45 by 30 by 6 inches and is engineered for large and senior dogs up to 75 pounds.

The trade-offs are real and worth stating plainly. This bed is not waterproof, so an accident means immediate cleaning or a ruined core. There is no anti-slip coating on the underside, so it can travel on hard floors. And the foam is shallow at the low point, which is why some large dogs bottom out without a crate mat underneath.

A subset of recent reviews also describes the foam as flatter and crumplier than earlier production runs, with a glued middle seam, plus reports of fabric shrinking and a zipper failing after one wash. Long-term owners are enthusiastic; newer buyers are more measured.

Choose this bed if your dog is a sprawler

The open sleeping surface means a dog that stretches out fully is not forced into a curled position. That matters more than it sounds, because a curled dog is not resting its full weight on the supportive core and gets less of the benefit.

The low profile also suits a dog whose hips are too weak to step over a bolster ring, which rules out most couch-style beds.

Skip this bed if incontinence is in the picture

There is no waterproof liner here at all. If your dog has accidents, you are buying a bed you may need to replace, so choose pick 2 or pick 7 instead, both of which have waterproof layers behind the cover.

Skip it too if your dog is over 75 pounds, since the slab is not specified beyond that weight.

5. Laifug 7 Inch Memory Foam Bed Is the Best Premium Pick for Hip Dysplasia

This is the thickest, most deliberate construction in our list. The core is 7 inches of 40D high-density memory foam topped with a 30D ultra-soft sponge layer, built out to 50 by 36 by 10 inches. Owners of dogs with hip dysplasia and arthritis consistently credit the slow rebound with easing mobility problems.

The dual pillow arrangement is a 3 inch main pillow plus a 1.5 inch auxiliary pillow, which gives a senior dog somewhere to rest its head without the chin dropping forward. There is a waterproof inner lining, a high-friction anti-slip bottom, and a removable machine washable cover with an SBS zipper.

Foam depth is the reason this bed works for heavier dogs. A 7 inch core does not bottom out at 100 pounds the way a 3 inch base does, so the surface stays level through the night and the hip joint is not taking the concentrated load on the floor.

The reservations are consistent enough to plan around. A minority of owners find the foam less dense and supportive than they expected under adult weight, which suggests the 7 inches include a lot of soft top layer. The 50 by 36 inch footprint is genuinely large, so measure the room, and the bed weighs 17.6 pounds, which makes it awkward to move. Variants run from 34 by 22 up to 60 by 48 inches.

Choose this bed if hip dysplasia or severe arthritis is diagnosed

When a vet has told you the joints are the problem, the number that matters is core thickness under the dog, and this is the deepest dedicated core we found. It also suits senior dogs from 90 to 120 pounds who need more than an egg-crate layer.

Pick it if you have the floor space and can live with the weight of moving it only occasionally.

Skip this bed if your dog is small or your space is tight

The XL footprint is 50 by 36 inches and the weight is 17.6 pounds. For a dog under about 40 pounds this is wasted space and wasted money, and the pillows will not be positioned where a small dog rests its head.

Give it 24 to 48 hours to expand to full height after delivery, and measure the spot before you order, not after.

6. WNPETHOME Cozy Senior Bed Is the Best Match for Small and Medium Seniors

Small and medium senior dogs are the most commonly underserved group in this category, mostly because most orthopedic beds are built large. This one covers 28 by 23 inches up to 71 by 46 inches, and it is marketed explicitly for elderly, senior and sick dogs.

The C-shape is the design choice worth understanding. Three sides are raised at 3.5 inches while the front stays open, so the dog can curl into a nest for security or lie flat and stretched out without climbing over anything. The base is 3.5 inches of high-density egg foam with a waterproof inner lining protecting against urine.

Reviewers consistently cite the secure nest and the reported easing of joint pain, and the bed holds an 81% five-star rating across more than 5.4k reviews. The rose pattern short plush surface is soft and easy on a thin old dog, and the zippered cover comes off for machine washing.

The critical caveat is load. The Large size is rated for dogs under 50 pounds. A 55 pound dog on that variant will push past the intended load, so size up if your dog is close to the ceiling, and size up anyway if your dog rolls around during sleep.

Choose this bed if your dog is under 50 pounds and likes a nest

Dogs that curl up and push their nose into a corner do better with a C-shape than with an open pad, because the raised sides support the head without loading the spine. The egg foam base gives a small senior enough loft to lift the hips off a hard floor.

It also suits an older, slightly anxious dog, since the enclosed shape reads as a den. If calm-down bedding is your wider concern, our guide to the best calming dog beds covers that angle in more depth.

Skip this bed if your dog is heavier than 50 pounds

This is a hard specification, not a judgement call. Once a dog is over 50 pounds on the Large size, the foam compresses faster and the joint support drops away sooner than you would expect.

Also skip it for a confirmed hip dysplasia case, where a solid slab or a thicker core like pick 5 is a better bet than egg foam.

7. CWAWZ Cooling Gel XL Bed Is the Best Pick for Hot Climates

Memory foam has a well deserved reputation for holding heat, and for a senior dog in a warm climate that is a real problem rather than a footnote. This bed puts a cooling gel foam layer on top of a 4 inch high-density orthopedic base, which is the combination we would look for in a double-coated or thick-coated senior.

The waterproof TPU lining blocks urine, drool and spills before they reach the foam core, and the fabric is OEKO-TEX Standard 100 certified alongside CertiPUR-US certified memory foam. That double certification is uncommon at this end of the category.

Reviewers of aging large dogs report real comfort gains, and several owners specifically mention the cooling layer as the reason their dog uses the bed in summer. The Dutch velvet cover unzips easily and survives a gentle machine wash, and the raised edges work as a headrest and a security cue for a dog that curls up.

The one consistent deduction is the setup period. The bed is vacuum packed and can take up to three days to fully expand at the corners and edges, plus around 20 minutes of assembly to fit the bolsters and mattress. Plan for it, or your dog may reject the flat, oddly shaped bed before it has properly puffed up.

Choose this bed if your dog runs hot

The cooling gel layer is the reason to pick this over any other egg-foam bed of similar depth. Owners of thick-coated seniors on tile report that their dogs stop moving to cooler floors during the day, which is the outcome you are paying for.

It also suits a senior with mild incontinence, since the TPU lining protects the core even where the plush surface does not.

Skip this bed if your dog avoids velvet in warm weather

Some dogs will not settle on a plush surface when it is hot, no matter what is underneath it. If your dog already refuses thick bedding in summer, choose a flat lower-pile option such as pick 4 instead.

Also allow three full days before judging it, because a bed that has not expanded is not the bed you bought.

8. INVENHO Egg-Crate XL Sofa Is the Most Versatile for Large Seniors

The XL is 42 by 32 by 7 inches and rated for dogs up to 80 pounds, and the brand is unusually clear about dog weight limits at every size, from Medium at 28 by 23 for dogs under 30 pounds up to XXL-Plus at 53 by 42 for 150 pounds. That clarity is worth something when you are buying for a dog whose weight sits near a boundary.

The C-shape chaise design has a four-sided 3.5 inch bolster, which is the most enclosed of the beds here, and a fish scale pattern plush surface that reviewers note resists shedding. There is a waterproof inner lining and a non-skid bottom.

Owners like the security of the nest and the softness of the plush, and the washable zippered cover is straightforward to remove. For a senior dog that likes to be enclosed, the four-sided bolster is the appeal, and dogs that feel more settled tend to sleep longer through the night.

The honest limitation is that this is egg crate foam, not a solid high-density core, so it sits at the softer end of the orthopedic category. The bolsters are fluff filled rather than foam filled and can compress over time. Neither issue is disqualifying for a dog under about 80 pounds with general stiffness, but both are reasons to choose something deeper for a diagnosed joint condition.

Choose this bed if you want an enclosed nest on a budget

Four sides of bolster is more enclosure than most of the beds in this list, and that suits a dog who seeks a den. The stated weight limits across seven sizes make it a good fit if you are sizing up for a rolling sleeper.

It pairs especially well with a washable blanket thrown over the surface, which keeps the plush looking new and gives your dog a familiar scent.

Skip this bed if your dog has confirmed joint disease

Egg crate foam conforms to the body, which feels soft but does not hold a level surface under a heavy dog. When a vet has diagnosed hip dysplasia or elbow arthritis, you want a dense core that resists compression, so pick 5 or pick 10 is a better use of money.

Skip it also if the fluff-filled bolsters lose their shape on the first wash, which some owners report.

9. iweepet Calming Nest Is the Best Low-Entry Bed for Weak Hips

This is the bed to consider when getting onto the bed is the problem. The lowered entrance is the defining feature, combined with a deeply filled side cushion that supports the head and neck without forcing a dog to step up and over a bolster wall.

The base is 28D high-density egg crate memory foam measuring 3.74 inches, inside a half-round wrap-around design. At 44 by 32.6 by 7.6 inches it suits dogs from 80 to 100 pounds, and the range runs from 36 by 27.5 inches up to 53 by 41 for dogs of 120 pounds and up.

Reviewers repeatedly report that aging dogs choose this bed over the others they own, which is the single most useful signal for a senior purchase. The wrap-around shape gives a security cue similar to a den, and the deeply filled cushion works well as a headrest for a dog that has lost neck muscle.

A few buyers find the cushion flatter than expected, and fluid can seep through at the zipper seam onto the foam, so wipe the seam after an accident rather than assuming the liner has caught it. The long plush runs warm, so some dogs avoid it in summer, and there can be an initial packing aroma that needs airing out.

Choose this bed if your dog struggles to climb on

The lowered entrance reduces the knee and hip load of stepping up, which matters when the problem is getting onto the bed rather than resting on it. Pair it with a rug or a ramp at the same time, since most owners who solve the climbing problem also improve traction on the approach.

It is also a good pick if your dog prefers a soft enclosed shape but you have found foam-only beds too firm.

Skip this bed if accidents are frequent

Although the inner lining is described as fully waterproof and washable, several buyers report fluid finding the zipper seam and reaching the foam. For a dog with regular incontinence, a bed with a waterproof film bonded across the whole surface, like pick 2, is safer.

It is the newest listing in our set, so it has the smallest body of long-term feedback here at about 1k reviews.

10. KOPEKS 7 Inch XL Bed Is the Best Pick for Post-Surgery Recovery

Post-surgery is where the reasoning changes. A groggy or painful dog needs a surface that keeps a limb supported and does not collapse into a crater under shifting weight, and that is exactly what a 7 inch memory foam core at 50 by 34 by 10 inches provides.

The integrated 3 inch headrest pillow is the detail that matters for recovery. After ACL, TPLO or hip surgery, a dog that cannot lift its head comfortably will guard the whole bed, so having a raised pillow in place rather than needing a separate one removes a step.

The waterproof inner protector gives a second line of defence during recovery, when bathroom accidents are common because of pain and restricted activity. The plush suede cover unzips for machine washing, and the anti-slip bottom keeps a bed stable when a dog shifts around getting in and out awkwardly.

There is also a 12-month limited warranty that explicitly covers foam integrity, zippers, seams and liner problems, which matters when a single component failing means replacing a large bed. Practical notes: it weighs nearly 16 pounds, the footprint is bulky at 50 by 34 inches, and the foam may take two to three days to fully expand, longer in a cold room.

Choose this bed if your dog is recovering from surgery

Deep foam plus a built-in headrest covers the two biggest recovery complaints, which are a dog that cannot settle and a dog that ends up on the floor beside the bed. Waterproofing during the recovery period when accidents are common is the third reason.

Place the bed where your dog already rests, not where you think is better, and put it on a non-slip surface so a groggy dog does not slide off the edge when trying to stand.

Skip this bed if you need to move it daily

At nearly 16 pounds with a 50 by 34 inch footprint, this is a bed you place once rather than a bed you reposition. If you need to move your dog between rooms, pick 2 at a much lighter weight is easier to handle.

Set it up three days before the surgery if you can, so the foam is fully expanded when your dog comes home.

How to Choose an Orthopedic Dog Bed for a Senior Dog

Match the bed to your dog’s symptoms

Start with the symptom rather than the brand. Morning stiffness that eases after a few minutes points to a deeper dense core. Nighttime accidents point to a bonded waterproof liner, not just a washable cover. Reluctance to get on the bed points to a lowered entry and open shape rather than a bolster ring. A dog that pants on a plush bed in summer needs a cooling layer or a lower-pile surface.

Stiffness plus diagnosed hip dysplasia, especially in a dog over 50 pounds, means a solid slab or thick memory foam core of 5 inches or more. Sleep and comfort complaints with no diagnosis usually resolve at the softer end, with egg crate foam in a bolstered couch.

Foam thickness and density by dog weight

These are the two numbers that decide whether a bed is genuinely orthopedic. Density is the one most listings never state, and it is the one that matters most, because low-density foam feels thick in a listing and flat in under a year.

• Under 25 lb: 3 to 4 inches of loft is enough, provided the density is solid.
• 25 to 50 lb: 4 to 5 inches, with a bolster or pillow if your dog curls up.
• 50 to 80 lb: 5 to 6 inches. This is the range where a 3 inch base starts bottoming out.
• Over 80 lb: 6 to 7 inches of dedicated core, not bolster-inclusive height.

Any foam under 3 pounds per cubic foot is filler, not support. CertiPUR-US certification is a useful proxy for knowing what is inside, and it appears on picks 3 and 7 in our list.

Measure before you buy

Measure your dog stretched out, from the base of the tail to the tip of the nose, and add a few inches. Then add at least a foot to the bed length so a curled dog is not forced against the edge.

Weight class alone causes a common failure: buy too big, and a small dog perches on the front edge and never loads the supportive core. Dogs that slide or hang off the side are the most common complaint in owner discussions about this category, and it is a sizing problem rather than a foam problem.

Flat pad or bolstered couch

The split among experienced owners is genuine rather than a marketing one. Bolstered and C-shaped couches suit dogs that curl, nest, and push their nose into a corner. Flat pads and open loungers suit dogs that sprawl on their side or have weak hips and cannot step over a raised ring.

The practical rule is to watch how your dog already sleeps. If they curl into a ball on the sofa, buy bolsters. If they stretch out flat on the floor, buy a flat or low-contour surface.

Getting your dog to actually use the new bed

This is the single most common frustration in senior dog bed discussions, and it is rarely a quality problem. Dogs refuse unfamiliar surfaces for three reasons: the location changed, the material smells or feels new, and the bed is in a place they were told not to go.

Put the new bed exactly where the old blankets were, or where the dog already sleeps. Lay the old blanket or a familiar fleece on top of the new bed so the surface smells like something the dog already trusts. Reward the first few nights rather than only when the dog is on it. Do not move the bed for at least two weeks, and expect roughly a month before a very set-in-routine dog fully accepts a change.

Waterproofing, washing and lifespan

A washable cover is table stakes; a waterproof liner is what actually protects the foam. Covers get washed weekly, liners never get washed at all, so anything that reaches the liner stays there. For a dog with occasional accidents, a bonded film layer like pick 2 is enough. For regular incontinence, treat it as the deciding feature.

Foam compresses. Press a hand into the deepest point where your dog lies and let go. If the surface does not return to level within a few seconds, the core has failed and pressure is back on the joints. Expect to replace a heavily used bed every 12 to 24 months, and a lightly used one every three to five years. Watch the warranty as a durability proxy, and note that pick 10 is the only bed here with a written 12-month warranty covering foam collapse, zippers, seams and liner.

When an Orthopedic Bed Is Not Enough

A bed controls pressure on a resting surface. It does not manage inflammation, muscle wasting, or a joint that has already changed shape. If your dog is reluctant to rise, yelped getting up even once, or starts to use a different leg than before, that is a veterinary conversation rather than a purchasing one.

Persistent panting at rest, a change in drinking or urination, or an accident that appears suddenly without warning all need the same response. Beds do not treat hip dysplasia, they manage comfort while a vet manages the condition.

The other half of a senior setup is often outside the bed frame. Non-slip rugs along the route to the bed, and a ramp or steps for a sofa or car, do more for a stiff dog than a marginally better mattress. Our guides to elevated dog beds and dog harnesses for large dogs cover the support side of the same problem, and if a small senior tires on walks, our dog stroller picks may be the practical answer to the mobility question.

Frequently Asked Questions

The Bottom Line

The best orthopedic dog beds for senior dogs are the ones that stay level under your dog’s weight, have a waterproof layer if accidents are part of the picture, and sit low enough to climb onto. Start with the JOYELF XLarge Memory Foam Bed for the best overall balance of support, washability and review depth.

Move up to the Laifug 7 Inch Memory Foam Bed if your dog is heavy or has a diagnosed joint condition, sideways to the EHEYCIGA XL if waterproofing is the deciding factor, and to the KOPEKS 7 Inch XL if recovery from surgery is the reason you are shopping. If your dog refuses the bed, put it where the old blankets were and give it a month before you judge it.

Whichever you choose in 2026, measure your dog stretched out, check the foam density, and test the spring-back every few months.
