Finding bald patches on your rabbit's coat can be unsettling — and it's not always easy to know what's causing them. Fur loss in rabbits has several distinct causes, each with its own treatment.
Is Some Fur Loss Normal?
Yes — rabbits go through seasonal molts typically twice a year. During a molt, you may find large clumps of fur coming out easily, and the coat may look patchy for a few weeks. This is normal.
What is not normal: defined bald patches, skin redness, flaking or crusting, intense scratching, or fur loss that doesn't resolve within a few weeks.
Common Causes of Abnormal Fur Loss
Fur Mites (Cheyletiella parasitovorax)
The most common skin parasite in rabbits, fur mites cause patchy fur loss with white, flaky scaling — often along the back toward the hindquarters. Sometimes called "walking dandruff." Affected rabbits may scratch or seem uncomfortable. Treatment with ivermectin or selamectin from a rabbit-savvy vet is highly effective.
Ringworm (Fungal Infection)
Despite the name, ringworm is a fungal infection that causes circular, scaly bald patches most often on the head, ears, and face. It can spread to humans and other pets, making prompt treatment important.
Barbering (Over-grooming or Dominance)
A dominant rabbit may chew and pull fur from a subordinate. Signs include neat bald patches and no skin irritation. In single rabbits, stress or boredom can lead to self-barbering.
Hormonal Causes (False Pregnancy)
Intact female rabbits sometimes pull their own fur to build a nest even when not pregnant. Spaying usually resolves this.
Bacterial Skin Infection
Moist or soiled bedding can cause skin irritation and secondary bacterial infections, especially under the chin or around the hindquarters.
When to Worry: Emergency Signs
Take your rabbit to an exotic animal veterinarian immediately if:
- Bald patches are accompanied by open sores or wounds
- The skin looks raw or has pus
- Your rabbit has become lethargic or stopped eating
- You see fly eggs or maggots in the skin (flystrike — a life-threatening emergency)
What to Do at Home
Keep the living area dry and bedding clean. Do not apply human or dog/cat parasite treatments to rabbits — many are toxic. Always use vet-prescribed products formulated for rabbits.
