So I have owned my new horse for about 6 months now and may be ride 2 times a week with just some trail riding usually. Today after coming back from trails he started to drag his toe when walking, he was also stumbling more than usual, nothing definitely major or harshly noticeable but scared me enough to get off and walk back to the barn, when we got back sure enough he was slightly favoring the same leg but not stumbling anymore, found no signs of heat in his leg or hoof and he is barefoot and not really what you would call tender footed normally, also nothing lodged in side his frog or anything, After turning him out he persisted to roll get up and trot away ( of course favoring the leg) but there was a very noticeable clicking sound as he was moving, so my question is what are some diff types of symptoms from a shoulder injury and like a tendon or leg issue? Do they carry the lame leg in diff ways? Is one more serious than the other? What are treatments you can do before the vet comes out? Is there a process of elimination you can do yourself?
