I'll be calling the vet as soon as my mom gets home from work, but over the past few weeks or so my Jack Russell has had a blister-type thing on the inside of his front leg, on the carpus I believe. I never paid any mind to it because it appeared to be a cut (he's outside in the barn and constantly gets scrapes from digging and chasing raccoons, rabbits, etc) and didn't bother him in the last. Today when I got ome from school, however, he was limping badly (would not put any weight on the leg) and was very mellow and quiet. He's laying on his back next to me right now, instead of begging to be let outside, which is....different.
It looks like a blister; it's dark pink and bubble-shaped, protruding from the inside/top of his "knee" on his FR leg. It doesn't seem to be tender when touched, but like I said, he won't put weight on it. He's licking it.
Can I give him equine Bute or something? I hate to see him in pain, however minimal it might be.
Like I said, I'm calling the vet when my mom gets home. Just wanted opinions as to what it might be. Food hasn't been changed; free choice of the same stuff we've been using for the past six years; water available 24/7, never any medical problems before this. I'm going to get my camera to take a picture to show you guys.
