When I went out to feed everything this morning, I noticed my six month old runner/runner mix didn't come over to greet me like she normally does. I found her laying down just outside of their house, and after prodding her for a minute, offering her food, and finally just standing her up, I determind something is wrong with her feet. I took her inside and let her swim a bit before I attempted to check her feet out, and found a small scan on the bottom of the bad leg, and a knotted up scabby area on the one she's putting pressure on. Does this look like bumblefoot? Is so, how do I treat it? If not, any ideas as to what it is? Bad foot: Foot she's putting pressure on: (Forgot to mention her feet are also very red.) They were not like this yesterday and she was walking fine. Bumblefoot?
