There are several very good reasons why you should keep the hair on your pooch's paws shaved. For starters, doing so will make it much easier for you to spot any injuries. If you live in an area where it snows, short hair will eliminate the risk of ice building up on her paws. When you trim the hair between her pads, you reduce the risk of mats building up between them and making it painful for her to walk. No matter what time of year, there is always something that can get caught up in your pup's paws and pads if you don't keep them well groomed.
Keep in mind, paws are extremely sensitive and your dog is not likely to enjoy having them handled, trimmed, or shaved. You need to go slow and give her time to get used to the clippers. The more time you take, the more you talk to her, and the more relaxed you are, the easier it will be to get the job done.
While it might seem to be a bit daunting at first, this is a task both you and your dog must master. The last thing she wants is to be walking around in pain because her paws have matted hair between the pads or she has ice balls stuck in the hair on top of them. It only has to take a few minutes a month to get the job done, but she is sure to appreciate it.
