Rabbit pododermatitis — known as sore hocks or ulcerative pododermatitis — is graded I through V based on how deep the pressure injury on the rear feet has gone. Mild stage I redness can resolve in 2 weeks with husbandry changes, while stage IV abscessation and stage V tendon involvement often need months of bandaging or surgery. Roughly 30 to 40 percent of pet rabbits develop some grade of pododermatitis in their lifetime, with overweight rabbits and rabbits on hard or wire surfaces at highest risk (Mancinelli & Lord, 2014, JEPM). Knowing what stage you're looking at tells you whether to fix the cage or call the vet.

What Pododermatitis Actually Is
Pododermatitis is a pressure-and-friction injury on the underside of the rear feet (and sometimes the front feet) of rabbits. The hocks bear most of the rabbit's weight when sitting. Constant pressure on a hard, wet, or abrasive surface — wire cage flooring, soiled bedding, or thin carpet over concrete — gradually breaks down the protective fur and skin, leading to ulceration and, eventually, deeper infection. The condition is graded I to V based on depth and complications, and the grade dictates how aggressive treatment needs to be.
Stage I: Fur Thinning and Mild Redness
Stage I is the earliest visible change. The fur over the rear hocks looks thinner, parted, or matted, and the skin underneath shows mild redness without ulceration. The rabbit is fully comfortable and acts normally. Almost every rabbit on a hard surface eventually shows some stage I changes. Intervention at this stage is purely environmental — soft flooring (fleece blankets over a soft mat, deep clean hay bedding), weight loss if overweight, and litter box hygiene. Most stage I cases reverse in 2 to 4 weeks with husbandry alone. The 2014 review of rabbit pododermatitis found that environmental factors (cage flooring, weight, hygiene) explained the majority of disease occurrence (Mancinelli & Lord, 2014, JEPM).
Stage II: Hyperkeratotic, Calloused Skin
Stage II shows a thick callous on the hock, often with a smooth, hairless, leathery surface. The skin is still intact. The rabbit may be slightly sensitive to handling of the hock but is not lame. Treatment at this stage is still primarily environmental, with the addition of regular gentle cleaning and a thin layer of vet-prescribed barrier ointment as needed. Stage II rabbits often stabilize at this grade for years if husbandry is corrected, though some progress despite good care because of underlying skeletal or weight issues.
Stage III: Superficial Ulcer
Stage III is the first stage where the skin breaks. A shallow ulcer appears on the weight-bearing surface, often with crusting or scabbing. The rabbit may shift weight or be reluctant to hop normally. Treatment now requires vet involvement: gentle cleaning under sedation, a soft padded bandage that is changed every 3 to 5 days, NSAID pain control (typically meloxicam), and aggressive husbandry correction. As described in Quesenberry and Carpenter's Ferrets, Rabbits, and Rodents, stage III cases typically heal in 4 to 8 weeks with strict bandage management. Pain control matters here both for welfare and to keep the rabbit eating and moving normally; the 2019 review of rabbit pain emphasizes that NSAIDs and opioids are appropriate and necessary for ulcerative pododermatitis (Benato et al., 2019, JSAP).
Stage IV: Deep Ulcer With Abscess Formation
Stage IV is full-thickness ulceration with secondary bacterial infection and often a tracking abscess. Pus may be visible in the wound. The rabbit is typically lame on the affected leg, reluctant to hop, and may be hunched and slow. This is now a multi-week to multi-month treatment course: surgical debridement under anesthesia, abscess capsule removal, culture-directed antibiotics, prolonged bandaging, repeat sedated bandage changes, and intensive husbandry correction. Treatment costs and time commitment are substantial, and outcome depends heavily on owner ability to maintain bandaging.
Stage V: Tendon and Bone Involvement
Stage V is end-stage disease where the infection has reached the deeper tendons, ligaments, or hock joint itself. The rabbit is often severely lame or non-weight-bearing. Treatment may include long-term antibiotics, repeat surgery, and in some cases reluctant discussion of amputation versus humane euthanasia. Outcomes at stage V are poor without intensive specialist care. The 2024 AEMV exotic mammal care guidance emphasizes early intervention because stage V cases are largely preventable with adequate husbandry (AEMV Pet Care Guides, 2024).
When to See a Vet
Call your vet today if:
- Your rabbit's hock fur looks newly thin or matted
- Visible callous, redness, or sensitivity over the rear hocks
- Any open sore, scab, or ulcer on the foot
- The rabbit is shifting weight, sitting differently, or moving less than normal
- Overweight rabbit on hard or wire flooring (preventive workup)
Go to the ER immediately if:
- The rabbit is not eating or producing fecal pellets (GI stasis is always an emergency)
- Profound lethargy or hunched posture with teeth grinding (severe pain)
- Visibly purulent open wound on the foot with foul smell
- Sudden non-weight-bearing lameness with swelling extending up the leg
- Wound bleeding heavily after self-trauma

Frequently Asked Questions
What are the stages of rabbit pododermatitis?
Stage I is fur thinning and mild redness; stage II is calloused hyperkeratotic skin with intact surface; stage III is a superficial ulcer with broken skin; stage IV is a deep ulcer with abscess formation; stage V is tendon, ligament, or bone involvement. Stages I and II are managed with husbandry alone; stage III needs vet involvement and bandaging; stages IV and V require surgical management.
How much does rabbit pododermatitis treatment cost?
Initial exotic vet exam runs $75 to $200 in the US (exotic vet premium). Stage III management with sedated cleaning and serial bandage changes is typically $300 to $800 over 6 to 8 weeks. Stage IV surgical debridement and prolonged bandaging runs $1,000 to $3,000. Stage V cases with long-term antibiotics, repeat surgery, or amputation can exceed $4,000. Soft cage flooring and weight management cost under $50 and prevent the vast majority of cases.
Can rabbit sore hocks heal on their own?
Stage I changes often reverse with husbandry alone. Stage II rarely progresses further if flooring and weight are addressed. Stage III and beyond do not heal without active medical management — they tend to worsen. Catching disease at stage I or II is the realistic goal.
What cage flooring is best to prevent pododermatitis?
Soft, dry, clean surfaces are key. Many exotic vets recommend a deep layer of timothy or orchard grass hay, fleece blankets over a soft mat, or thick towels rotated daily. Avoid wire cage floors entirely. If the rabbit is litter-trained, ensure the litter box is large enough that the rabbit isn't standing on the hard edge. Clean and dry the cage daily.
Are some breeds more at risk?
Yes. Rex rabbits (whose paw fur is naturally less protective) and large or giant breeds (Flemish giants, French lops) are at the highest risk. Overweight rabbits of any breed are at significantly elevated risk. Older arthritic rabbits who shift weight to the hocks during rest are also predisposed.
Still Not Sure if Your Rabbit Needs a Vet?
When you're not sure if this is wait-and-see or call-tonight, Voyage AI Vet triages in under 2 minutes. Describe what you're seeing in chat, share photos of the underside of the rear feet (gently tip the rabbit on a towel to see), or hop on a live video call if you want a second pair of eyes. Every answer comes with citations to the actual veterinary literature it's pulling from — so you see exactly where the guidance comes from, not just a chatbot's word.
