I don't know how often I really clip them.. I just clip them when they seem to be getting long. Tasha nibbles her own nails a lot so often I only have to clip one or two. She has black nails too so it's hard to tell, I just try to take off the ends. I do know the less you clip them the longer the quick will grow up into the nail so it's best to keep them trimmed.

I use clippers like the one Shelteez pictured. The other kind, I think are called guillotine, that was the first clipper I had and used with the collies, but I find I like the side clippers better.

Tommy really hates it and can be squirmy, but Tasha is like Abbey, she sits and gives me her paw and waits and then gives me the other paw when I ask for it. She's a little less certain on the back legs but she's still very good.
