sprain in fetlock, not lame but awkward in the canter
Hi I was hoping for some advice. I got a horse on loan. It's been out of work for a few years so bringing it back to work. It's 10 years old. He lacks muscle and does not yet track up in the trot. He recently slipped in a small ditch. There was a small cut and slight swelling above and below the left hind fetlock joint. This was treated and he was given rest and cold hosing twice a day. After 2 weeks The swelling has continued to reduce and goes away with turnout or slight exercise. The horse has never been lame but appears to slightly twist the fetlock on the left hind when he places it can be seen slightly in walk in the arena but not on hard ground. ( I think he was like this before the incident but can't remember). This cannot be seen in the trot. I cantered him today and it was very awkward particularly on the right rein. I got someone to watch me and they said it looks like he is fish tailing with his left hind leg. It appears that he does not want to put all his weight on his left hind leg which is more obvious at canter. I am wondering what it is; some sort of sprain and if there is anything you would advise? I wanted to call the vet but more experienced people at the yard think that because it's not lame I am being paranoid and I should just give him a weeks rest and see where it goes.
