Today, I was riding my horse when I noticed that the 3 mischevious Shetland ponies had escaped and were running toward the road (that's not too far from the highway.)
So I had to quickly tie Putts up to an insecure gate panel.
Long story short, when I was rounding up the ponies, he spooked and took the gate with him. I didn't see exactly what happened, but when I came back to him, he had broken his halter off (thank God for cheap nylon, I guess?) and was just chilling with one of his legs cocked. I didn't think much of it until I started to lead him back to the barn and noticed a limp in his back leg. I obviously had a slight panic attack and checked his leg over, but nothing seemed wrong to my untrained eye. No scratches, no cuts, nothing. I don't notice any profound swelling but since he's got his winter coat already it's hard to tell exactly. It's also not really tender either. I was putting pressure on various parts of his leg and he only flinched a little when I sweezed right above his hock (that area) and slightly when I squeezed his fetlock. As I led him a little bit he seemed to 'walk it off', but even after a half hour he's still limping on it and cocking it when he stands.
My dad guessed a pulled/strained/bruised muscle, and I kind of trust that, but I'm still a little worried.
What would you say; should I call a vet now or wait a week and see if it gets better? What would you do?
