I have had my Pyr for only about a month now and her nails are getting kinda long. She's 6 y.o. so pretty big and her nails are huge! They're just really thick! I can't get through them with any pair of regular dog nail clippers I've found. I've tried the ones that are kinda like scissors and the guillotine kind. Nothing has worked! It either does nothing at all to her nails or will shatter them. Can anyone recommend anything that will get through those big nails?
