I recently bought a horse and learned the hard way to do a vet exam PRIOR to purchasing. I got a grade horse being sold as a sound trail horse. After getting him home and cleaned up, I found a racing brand, and found out he used to be a sulky racer and is a registered Standardbred. He was actually pretty good, and obtained a suspensory injury which ended his career. After riding him a few times he started to get a slight hitch to his back leg. When I took him to the vet to get an exam and vaccines, the vet noticed his stifle was swollen. He also pointed out that both back legs had been pin fired. After examining it closer he determined that the horse was partially lame in the back left stiffle and would only be sound for light riding. He prescribed an anti-inflammatory and said that if the swelling went down and he started using the leg more he might become more sound. The vet said not to be too hopeful though, because I was probably an old injury and there's probably not much to be done. Were getting it x-rayed after his meds are done to see how bad it is.
Now what I'm confused about is the horse has tons of get up and go. He loves to be ridden and goes strait into a canter if you just click your tongue. I don't let him do more then a walk, and only do short rides to work his leg per doctors orders, but he doesnt limp and doesn't seem to be in pain. Should I seek out a second opinion on his leg?
Oh, and the anti-inflammatory isn't working, the slight swelling doesn't look any different and he's been on them for 2 weeks. He's also been on joint supplements. He tosses his head and bucks around when you go to feed him in the morning too. I've never heard of a lame horse doing that
