πŸ“ Summary

A throat lump in rabbits is often a normal dewlap, but can be ringworm, infection, or heat. Treat by isolating and antifungal care, antibiotics, or a cooler diet.

1 Causes of a Lump Under a Rabbit’s Throat

1. Dewlap. Usually a throat lump is simply the dewlap, normal in adult females and a few obese males; no need to worry. But if the lump is hard and affects daily life, take the rabbit to a vet.

2. Ringworm. The lump may be ringworm on the neck. Check for scaly patches, hair loss, redness, or crusting. If present, isolate the rabbit since it is contagious, trim the neck fur, clean the area with hydrogen peroxide, and apply antifungal cream until it improves.

3. Inflammation. A respiratory infection can cause inflammation; the itchy rabbit scratches, causing red swelling that looks like a small red lump. Give anti-inflammatory antibiotics per instructions to avoid poisoning.

4. Internal heat. If the lump comes with yellow urine and dry stools, it may be heat. Encourage more water and feed vegetables or fruit to cool it down, and avoid salty, oily human food that upsets the gut.
