My yearling has a small swollen area on the back of all.four pasterns right above the bulb of his heel buy it is definitely worse on his RH. He is bred to be a big boy and am wondering if it could be a growing thing but I don't want to chalk it up to growing and then find out something is really wrong. He is not lame but a cold hosed it and gave him a little bute to see if it would help but there was no change. Has anyone ever seen this before? I will try to post a picture of it.
