Rabbit Hair Loss: Causes, Mites, Ringworm & When to Worry
Hair loss in rabbits has many causes — fur mites, ringworm, barbering (chewing by themselves or cagemates), hormonal disease (in intact females), and molting — with very different treatments. The location of hair loss, whether the skin underneath looks inflamed or normal, and the rabbit's overall health all help narrow down the cause.

Why Is My Rabbit Losing Hair?
Rabbits normally shed (molt) several times a year, sometimes dramatically — a rabbit in a heavy molt can look like it's losing large patches of fur over days. This is normal and not a health concern. The challenge is distinguishing normal seasonal shedding from pathological hair loss.
Pathological alopecia (hair loss) in rabbits is worth a vet visit when: the skin underneath looks inflamed, scaly, crusted, or irritated; when the rabbit appears itchy or uncomfortable; when the bald areas are spreading; or when the rabbit is losing weight or acting unwell. As described in Quesenberry & Carpenter's Ferrets, Rabbits & Rodents: Clinical Medicine and Surgery, the most common causes of pathological alopecia in domestic rabbits are fur mites, ringworm, and barbering, each with distinct characteristics.
Common Causes of Rabbit Hair Loss
Fur mites (Cheyletiella parasitovorax) are the most common parasitic cause of hair loss in rabbits. They produce a distinctive pattern: heavy, white, flaky dandruff ("walking dandruff") on the back and rump, sometimes visible movement (the mites carry the scales). Affected skin may be mildly red and the rabbit may scratch or groom excessively. Fur mites are transmitted rabbit-to-rabbit and can cause transient skin irritation in humans. Treatment is ivermectin or selamectin.
Ear mites (Psoroptes cuniculi) don't directly cause body hair loss, but rabbits with severe ear mite infestations sometimes traumatize the area around the ears through scratching, leading to hair loss behind and around the ears.
Ringworm (dermatophytosis) causes circular, scaly, often red patches of hair loss, typically on the face, ears, and forelegs first. The affected skin may have a crusty border. Ringworm is contagious to humans. Diagnosis is via fungal culture (Wood's lamp illumination is unreliable in rabbits); treatment is antifungal medication (topical or systemic).
Barbering — one rabbit chewing another's fur — produces clean-edged patches of hair loss, usually without skin irritation. The fur may look clipped rather than broken. Dominant rabbits barber subordinates, particularly around the face and flanks. Self-barbering (pulling one's own fur) can indicate boredom, stress, or pain. A rabbit pulling fur from its belly and building a nest is preparing for a pseudopregnancy (false pregnancy) — normal in intact females.
Hormonal disease in intact females: Uterine adenocarcinoma, ovarian cysts, and pseudopregnancy can all cause fur pulling and alopecia around the belly in intact female rabbits. The AEMV Exotic Pet Care Guides, 2024 recommend spaying all female rabbits by 1–2 years to prevent uterine cancer, which affects the majority of unspayed rabbits over age 3.
Dental disease: Rabbits with incisor or molar problems may develop hair loss around the chin and cheeks from salivation and rubbing.
When to See a Vet
Call your vet today if:
- The bald area has red, scaly, or crusty skin underneath
- You see white flakes or "dandruff" on the back (possible mites)
- Your rabbit is scratching or appears itchy or uncomfortable
- The hair loss is spreading rapidly
- Your rabbit is an intact female and is pulling fur from her belly repeatedly
Go to the ER immediately if:
- Hair loss accompanies weakness, not eating, or neurological signs
- There are wounds or fly strike (maggots) on the skin

Frequently Asked Questions
Is rabbit hair loss always a sign of disease? No. Rabbits have dramatic seasonal molts 2–4 times per year — fur can come out in clumps and the rabbit may look patchy during heavy shedding. If the skin underneath appears normal and the rabbit is eating well and behaving normally, molting is the most likely explanation. If the skin is affected or the rabbit seems unwell, a vet evaluation is needed.
Can I catch rabbit hair loss causes from my rabbit? Ringworm (a fungal infection, not an actual worm) is contagious to humans — it causes circular, itchy skin patches. Fur mites (Cheyletiella) can cause transient skin irritation in humans but don't establish permanent infections. If your rabbit has either of these, wash hands after handling and see your doctor if you develop skin lesions.
How much does treating rabbit hair loss cost? A vet exam with skin scraping and fungal culture runs $100–250 at an exotic vet. Ringworm treatment (antifungals) costs $30–80/month. Mite treatment (selamectin or ivermectin) runs $20–60 per treatment, usually repeated 2–3 times. An exotic vet premium of approximately 1.5–2× standard rates applies.
How do I treat rabbit fur mites at home? Do not treat rabbit fur mites without veterinary guidance. Ivermectin and selamectin are effective, but incorrect doses can be fatal in rabbits. A prescription from an exotic vet is necessary. Thoroughly clean and disinfect the enclosure to remove mites from the environment.
Why is my rabbit pulling out her belly fur? Fur pulling from the belly in intact female rabbits typically signals pseudopregnancy (false pregnancy) — a hormonal response that triggers nest-building behavior. This resolves on its own but recurs repeatedly in intact females. Spaying eliminates the cycle and dramatically reduces uterine cancer risk, which affects most intact females over age 3–5.
