New to the board and looking for advice for our GSD Charlie who is 15months. About 8 months ago we took him to the vet because of hot spots, excessive loss of hair and sores in his ears from itching. He started on orijen large breed, then switched to acana lamb and orchard apple after the vet recommended, then switched to GO! sensitivity (salmon), now he is on firstmates pacific ocean original... each time it gets better then goes worse and now its worse as it ever been.
Just don't know what to do next!!!!!
