I'm human too 2 dogs that have allergies and I can only come up w/something in the air,like dust.I've changed their food etc.When it is really severe I give them a course of antibiotics {with acidophilus b-4 of course}until the sores are gone. I give them fish oil which is the only thing I've found that keeps them comfortably and not chewing constantly.It really works!The Vet says steriod shots which work great,but will kill the doggie in time.He said better to have one year less w/the dog than have them miserable. He's not their Vet any longer!
