Grooming your puppy is very important. Why? Because the more time you spend taking care of your dog, the happier, healthier, and hopefully longer life he will have. You may look at your puppy and think that you don't have to worry about most of the grooming chores until he's older. Not true, especially if your puppy is a double-coated or long-haired, or a terrier. All of these dogs need lots of attention.
