I have a 5 1/2 month old Corgi named Chipper. He's the best!!! (which I'm sure everyone says about their corgi - haha). However, he sheds a LOT. He eats high-end puppy food (Eukenuba lamb & rice) and we brush him pretty frequently. It's usually his hind end and tail that shed the most but he's pretty sensitive - as in you can brush him for a few minutes with the wire brush but then he hates it. Any suggestions how to keep the shedding to a minimum?
