I'll be calling the vet on Monday, but I wonder if anyone knows what this might be? I first felt it on Thursday night and it hasn't changed since. It doesn't look like an injury and it seems to be just a surface thing. Not bloody but sort of wet. No other spots on his body that I found. I don't think its causing him much pain bc he doesn't mind when I pet near or on the spot. He's acting totally normal and I haven't seen him licking it at all.
