My staffy is 6 nearly 7 and is suffering with terrible skin, he had been down the vets ( which he is scared of). We have enough had skin scraps and blood test and he was also on steroids and antibiotics to see if that helped which it did but they wont give anymore. his skin is so brittle and bleeds if he catches it. We have tried antihistamines and coconut oil but he keeps noring himself. Any advice would be most appreciated not sure what else to try.
