My dog is 5 years old and in the last 2 years he has broke out in sores, when he is on antibiotics the sores clear up but as soon as you stop them he breaks out again sometimes slightly worse. Can anyone tell me if there is any natural remedies out there which might help? Anything would be much appreciated, thank you.

What are you feeding the dog? Try a grain-free diet, preferably raw. I had a Bull Terrier with a similar issue, and it cleared up right away with a raw diet.
