My pup oscar, about 5 1/2 months now, has been itching and biting himself. Heâ€™s got bald spots all over his legs, armpits, and backside. Iâ€™ve taken him to the vet multiple times, theyâ€™ve given me medication for fleas, mites, allergies, and special skin shampoos, but nothing is working. Heâ€™s been scabbing up behind his ears, and weâ€™ve noticed his lip and leg bleeding (presumably from all the itching). Heâ€™s been gnawing on his bits so much itâ€™s seemingly bruising him. The skin on his penis is turning black, and thereâ€™s a bump under the skin around the tip. Heâ€™s also lost 2 teeth recently (Iâ€™m assuming his baby teeth), but I couldnâ€™t be sure with everything else going on. My vet recommended apoquel for the itching, but I read that itâ€™s not good for dogs 12months and under. Iâ€™m really worried, because this has been going on a few months now and I canâ€™t seem to figure it out.
