My 14 year old POA gelding has bony knobs on the insides of his hocks. They're not very big or noticeable, but I notice them just because I'm always around him. I've always wondered what they were, but because he's never shown any signs of being lame, or even sore on his back legs, I never gave it a second thought. I happened to have read about bone spavin/bone spurs and I've noticed them more lately (maybe just because I'm looking for them now..) but I thought maybe that's what those could be. He shows no signs of arthritis, and he still moves like he always has. Do you think they're spurs, and should I have them looked at?
