I know I used to do it when I was younger, and I know it is a very popular thing for young girls to do to their dogs. My daughter is getting to that age where she wants to paint our dog's nails. Now that I am older, I am thinking, is this harmful to the dog? I could see my dog chewing the paint off-she is sassy like that. I guess I may have to be the mean mom that says no! lol. What is your intake on painting dog nails.
