My dog is 5 years old he has had a black bump on his front right leg since he was born. It seemed like it was just an extra toe pad. Recently this bump has turn a red/pink/gray color. I am taking him to the vet tomorrow. Does anybody have an idea to what it is?
The vet tested the bump by drawing some fluid and told us it is a Histiocytoma. It's basically a benign tumor that our vet said puppies are prone to getting. They typically go away on their own in about 3 months, so we are not doing anything for a treatment.
If anyone finds a bump like this, don't assume it is histiocytoma, because it could be malignant tumor or something else.
