Samson was the same way 2 years ago. I thought he was going to be bald!

The solution turned out to be a diet of lamb & rice with the addition of Omega fatty acids. Before I put him on the new diet, I ruled out any invisible critters by dipping him (and all the dogs). I also used the squirt bottle. In about 3 months, he was scratching only occasionally. I have continued to feed him and the other dogs Nutro Lamb & rice, but discontinued the fatty acid capsules.

I've been trying to break him of excess barking lately. I accidentally grabbed a squirt bottle that had a little vinegar and water last night. THAT sure got his attention!
