Question Hi, I have notice a black crusty lump on my rabbit's side, just behind her right shoulder. It is hard and there is fur growing on it.
She is a house rabbit so I doubt it's insects; she's never been outside. I've had her for about 3 months and never seen anything like this before. Any ideas?
Answer Dear Hayley,
Rabbits occasionally develop melanomas. I would have this looked at by a rabbit-savvy vet, and perhaps ask that a biopsy be taken under local anesthesia so the lesion can be characterized.
If the mass is of noticeable size, it might be best to have it completely removed with good margins (probably under general anesthesia, but some vets can do this with light sedation and local anesthetic), in case it is a melanoma.
If it is not attached to underlying tissue, such as muscle, bone, or fascia, the prognosis is better than if it *is* attached. So the sooner this is done, the better.
I've lived with companion rabbits for more than 35 years, and consider them members of my family. I can answer any questions about the biology and health of rabbits, from the commonplace to the unusual. But please note:
RULE #1: THE INTERNET IS NOT THE PLACE TO SEEK HELP IN AN EMERGENCY.
If your rabbits is LETHARGIC
If your rabbit is NOT EATING
If your rabbit is PHYSICALLY INJURED (including broken bones)
