Perhaps one of the veterinary folks here can answer this.
My rabbit gnawed at its dewlap…a lot. First, it gnawed away all the fur. Then it kept gnawing and gnawing and eating at its dewlap until it was finally down into the meat - there was muscle or some tissue exposed (it was white, whatever it was). The wound started out really small but then it kept eating and eating at it until it was giant and red (with tissue hanging out) and really quite nasty to look at. Before it got to its worst state, the rabbit was taken to the local vet and she wasn’t sure why it was acting in such a way Prescription antibiotics were given and some soap or cleaner was provided, and both were used with regularity but the rabbit continued the behavior.
Anyway, the question is - why did the rabbit do that? Are there any diseases that might have caused it? Did it just go nuts?
It was let out to run around frequently, it was fed and watered well, it’s cage was kept clean. The odd thing is, I had the rabbit a few years before it started doing that. Before it went - insane, perhaps - it was quite normal.
