One of the important parts of keeping your dog groomed is making aure that their toenaols are not getting too long. When the dog is outside a lot, and runs around on sand or gravel, hey will often keep their own toenails short enough.
Dogs that live inside, especially the little dogs, often have overgrown toenails. Clipping the toenails can be hard or easy, depending on the color of the toenails, and the disposition of the dog. My Chipper totally hates having his toenails clipped; and he squirms and yowls, making everything even harder to do. Tootsie, on the other hand , doesn't care if i trim hers.
If you have a dogs who hates being clipped, it might be worthwhile to take them to a groomer, espcially ifit is a dog that you have groomed anyway.
Here is a short tutorial about clipping your dog's toenails, made by a vet office.
