Vulvar and Perineal Trauma in Rabbits

Vulvar and perineal trauma means injury to the tissues around a female rabbit's vulva and the area under the tail, including the skin between the genitals and anus. The injury may be mild, like a superficial abrasion or urine scald, or much more serious, like a deep laceration, puncture wound, crushed tissue, or damage involving the urinary or reproductive tract.

In rabbits, even small wounds in this area deserve prompt veterinary attention. The skin is delicate, the region is easily contaminated by urine and feces, and pain can make a rabbit stop eating or avoid normal urination. That combination raises the risk of infection, skin breakdown, dehydration, and gastrointestinal slowdown.

Some rabbits develop trauma suddenly after a fall, a bite, or a mating-related injury. Others develop it more gradually when wet fur, obesity, arthritis, urine leakage, or poor mobility leads to chronic moisture and skin irritation. Your vet's job is not only to treat the wound, but also to look for the reason it happened in the first place.

This type of injury can happen after direct trauma or from ongoing skin damage. Direct trauma includes bite wounds from another rabbit or household pet, rough or forced breeding attempts, falls, getting caught on wire flooring or cage hardware, and accidental injury during handling. Rabbits have powerful hind legs and fragile spines, so panic and struggling can lead to serious injuries if they are not supported correctly.

Chronic moisture is another major cause. Urine scald, sometimes called hutch burn, can inflame the perineal skin and lead to hair loss, ulceration, and secondary infection. Rabbits may develop urine scald when they cannot posture normally to urinate because of arthritis, sore hocks, obesity, spinal pain, weakness, or urinary tract disease. Damp bedding and poor hygiene can make the problem worse.

Your vet may also consider underlying reproductive or urinary disease. Vulvar discharge is not considered normal in rabbits, and blood or discharge from the genital area can sometimes reflect infection, uterine disease, urinary tract disease, or another condition that is irritating the tissues and making trauma more likely. Self-trauma from licking or chewing at a painful area can add another layer of damage.

Diagnosis starts with a careful history and physical exam. Your vet will ask when you first noticed the problem, whether there was a fall, fight, mating attempt, surgery, or urine leakage, and whether your rabbit is still eating, passing stool, and urinating normally. Because rabbits can be stressed by handling, some need gentle sedation for a thorough exam of the painful area.

Your vet will look at how deep the wound is, whether the tissue is contaminated, and whether the urethra, rectum, or reproductive tract may be involved. They may clip fur, flush the wound, and check for bruising, dead tissue, abscess formation, or signs of urine scald. If infection is suspected, your vet may recommend cytology or culture.

Additional testing depends on the rabbit and the injury. Common options include bloodwork to assess hydration and overall stability, urinalysis if urination is abnormal, and imaging such as radiographs or ultrasound if your vet is concerned about internal injury, urinary obstruction, reproductive disease, or tissue prolapse. The goal is to identify both the wound itself and the reason it developed.

Good prevention starts with housing, hygiene, and safe handling. Keep your rabbit on solid, clean flooring rather than rough wire surfaces, and check enclosures for sharp edges, broken plastic, or gaps that can catch delicate skin. Support the chest and hindquarters every time you lift your rabbit, because struggling and kicking can cause serious injury.

Check the rear end often, especially in older, overweight, arthritic, or disabled rabbits. Fur that stays damp with urine or stool can quickly turn into painful dermatitis and open wounds. If you notice staining, wet fur, odor, or redness, schedule a veterinary visit promptly so your vet can look for urinary disease, mobility problems, obesity, sore hocks, or reproductive disease.

Separate rabbits that are fighting, and supervise introductions carefully. If an intact rabbit is mounting aggressively or breeding attempts are rough, ask your vet about behavior, housing, and reproductive management options. Daily litter changes, dry bedding, weight management, and early treatment of mobility or urinary problems can all lower the risk of perineal skin injury.
