We found a bump on Charlie's neck. For a small dog its not huge, but maybe the size of a penny. It kinda looks like a scab, but I had never seen a tick before and was not sure if this was it. So we took him to the vet and the vet tech looked at it and agreed it was probably a wound from him playing with the dogs next door and just to keep and eye on him and not to be to concerned. Well we found another bump, its a lot smaller, same type of scabby thing. I don't know if we missed it before, but he has not played with the dogs since. It does not seem to bother him at all when touched, and the dogs next door at watched closely with him, but they have a newer puppy who clearly does not have a good bite inhabition. I hate to not let them play once in a while, but if this is the cause then I have no choice. I am not sure if I should wait it out a bit like the vet tech suggested, or get the opinion directly from the vet.
