Bingo! He was certain from just looking at it. I'm just glad he was okay with waiting until next week. Our dog isn't purebred but he's mostly black lab with a little husky.
This vet is really great. When "Sam" (Sorry Sam!) was still a puppy he got puppy growing pains (there's a technical term and I'm drawing a blank). Of course it hit on a Saturday night so we took him to a 24 hour animal hospital. They wanted to do about 200 worth of test. We finally got it out of them that really all you could do is give him something for the pain and let them get through it. Monday, we called the vet who said, "give him half a baby aspirin once a day." In a couple of days it was all over with and he was fine.
