My horse has little bumps in the same place on either side of his hocks (the sides facing eachother) that are about the circumference of a nickel or penny, and stick out about half that. They feel bony, and never change size or shape or anything - they've stayed the same for the past few years.
I was kind of worried that it was bone spavin? He never shows signs of lameness or anything (I didn the 'bone spavin test', and he didn't show signs of stiffness after I released his leg)... I just noticed that he had those bumps a while back, didn't think much of it until my friend's horse got diagnosed with bone spavin & she had larger bumps on her hocks, which made me a little worried.
Do you think it's just the shape of his hocks/legs or is it something I should be concerned about?
