Sponsored by Skinner's, this week's dog of the week is Rebel. Pictured on a grouse moor, Rebel is a two-year-old cocker spaniel who now has two full seasons in the shooting field under his belt and is very much enjoying his third, but that day on grouse was a special occasion. For your dog to be included, email ollie.harvey@twsgroup.com a picture and tell us all about them. Featured dogs receive a 15kg bag of food, via Skinner’s.
