I shave both my dogs in the summer months. We usually end up having to shave Molli because her fur gets matts in it. No way around that until I find a brush that acctually works better. I notice Sam is alot cooler when he has shorter hair. When he had long hair he used to pant and become restless because how hot he was after walks. Now he doesn't. Right now Sam's hair is the length of a lab. I think we will stop shaving him and just cut it this short once a year. The rest of the time we give him a cocker cut, leaving feathering on the legs and ears. (in my sig)
