I have a 9-10 year old dog, and she has a curled toenail. The one that doesn't touch the ground when she walks, and how it is.. is it's curled then there's a redish bump then the side of the curled nail goes into this bump, I was wondering can i cut it myself or should i take her to a vet/grooming place? .. she doesn't seem to be in pain, she just licks it all the time ... Please help!!
