I have a Yorkie, but his hair's always tangling. He's 5 years old, I live in a warm climate. Would it be acceptable to give him the 'puppy shave', or is there another way to keep it short to avoid the everyday hassles of grooming? I brush him, wash him, everything. I'm not being lazy about it, I just want to be able to take a break. I have 3 children, and he and my chihuahua make it 5. I love my lil dog, but what else could I do?
