Has anyone bought or used the Peticure? I can clip one dogs nails ok but the other one is a pain.We have to bribe her with a lollipop when we do hers. I am afraid to clip too far down on the pain in the but dog's nails. Athena's have been clipped good since we got her so I don't have to clip a lot if I do it every other week. I wonder if it is loud.
