Thank you guys....Im glad to hear the opinion is that it isnt serious.
I was just looking at some info from a bunch of different sites...they all said basiclly the same thing. A new splint will most likely be hot, swell and cause pain...an old splint will be cold, no swelling, usually no pain, and that means its already healed itself. It also says splints on the hind are usually more trama enduced...it also mentioned blind splints but this splint doesnt fit the description. Does all this sound right? If so my boy has an old 'cold' splint.
The sites also recommended having a vet look at a splint even if its old...Im much less worried though after reading. Ill make a vet call for an over the phone opinion and Ill get a vet to look at him soon as I have decent funds...in the mean time ill keep a close eye on it.
Thank you everyone!
