Keeping your dog’s nails neatly trimmed not only looks nice, it also is less stress on the dog’s foot. No long nails to splay the feet out. No long nails to jab into your foot either!

Having nine puppies means LOTS of nails to trim. I use a Dremel to grind the nails, which keeps them nice and smooth. For more detail, check out this old post.
