Question about lump on back of hock
I'm new to this forum and I am hoping someone can answer a question.
I have a nine year old appaloosa/mustang; he is in overall very good health but has a large bump on the back of his hock (point of hock). It doesn't seem to cause him pain and he has had it since I bought him over a year ago. The vet who examined him after purchase did not even comment on it. While it doesn't seem to bother my horse in any way (even when I touch it), I have noticed that it has gotten noticeably larger over time. Even the lady who runs the stable I board at said she has never seen anything like it.
Thanks in advance for any responses.
