Furry Oak

Oak has been having a bit of a problem. It's a really strange problem and I haven't been able to find a solution other then just waiting. His adult fur has grown in and his puppy fur is still there too. He is a giant ball of fur! He's not shedding and he's really hot most of the time. He has taken to sleeping outside on the deck, even yesterday when it was snowing! After supper, when its time to sleep, he asks to go out and stays there until bedtime, curled up, sleeping. I brush him every few days and get a teeny, weeny loonie sized pile of fur(sometimes). Strange as it may sound, I hope he starts shedding soon!
