My basset hound gets sores on his skin. Can't figure out if he has allergies, or just keeps getting some sort of bacterial infections. They eventually get bad enough to where he'll lose small patches of hair on his back & the skin is scaly & very flaky. He's on Iams Lamb & Rice, so I'm hesitant to think it's his food. Last time I took him to the vet they gave him a cortisone shot & put him on antibiotics for 2 weeks. Also gave me chlorhexiderm shampoo. Skin cleared right up, but after 1 month it's starting up again. Help!
Sounds like an allergy. You may want to see a vet dermatologist. Consider allergy testing. vetcare
