Help! I just found a strange, scabby-looking blister thing on my dog and I don't know what caused it. He does have fleas, not too badly, but this is different from the typical little flea bites here and there. The scabs/ flaky skin he usually has are either from the flea bites or from his allergies. What I just found seems to have pus inside and there are like four different spots in the same area. I'm scared!
