This is my first dog and hes awesome, recently just noticed that he has a red raised lump on his stomach. See picture
Does anyone know what this could possibly be? I touched it and it is hard, and it hurts him, he was very irritated by it when I touched it but other than that doesn't seem to bother him. He doesn't have fleas, I just treated him with front line but there are a few other pimple looking hives near this area as well.
this is right under his left rear leg
this I noticed is on his nose too, and he has a few more of these smaller pimple looking things under his right rear leg
Help me please! the vet isn't open until Monday!
