my boxer puppy Tyson is 8 weeks old today. i got him from a breeder at 6 weeks old. about 2 days ago i noticed that he had a red circle, about the size of a penny, on his belly. i then noticed 3 more that aren't as noticeable. that night he had diarrhea. before he fell asleep for the night i put a little bit of neosporin on the circles just to soothe them...even though i have not seen him scratch or bite at them at all. Just a few minutes ago today i saw that he has yet another one of these circles on his inner ear. this one is quite a bit bigger, about the size of a nickel. all of them are dried up in the center now, and his diarrhea has stopped. he is still eating, drinking, and playing as he normally does, but i dont want to just overlook those circles. the first thing that popped into my head was ringworm. i am going to take him to the vet sometime within the next few days, after i can make an appointment, but i would really like to hear what you all think this could be.
