Kim, if you really want to get to the root of his shedding problem, try Dinovite canine nutritional supplement for dogs. Go to their website arnd read their testamonials. I have used it for my dog Chelsea, and it works. I just ordered some for Wendy. It is great stuff.
Sad to say for our Wisconsin GSPs have not had signs of shedding yet with temps in the 30's highs in the 40s , recent Snow storm Dana that dumped over 10 inches of snow. Farmers are 3 weeks behind in getting out in their fields to plant. Most snow fall in Wisconsin in 100 years. But I just love the tips on this thread when we do if ever warm up and Rocky begins to shed.
