Sophie has white toes but black claws.
I've had differences of opinion with 2 vets about cutting them. In the first instance, the vet just cut her wonky claw so that it didn't touch the ground when she stands. She seemed to be continually catching it on things but no damage. The second told me off for leaving her claws too long. After advice from other, more experienced hound owners I did say I'd been told not to trim her nails too hard but...
Too late! With the first slice of the clippers, Sophie was squealing and limping around the room with a badly bloodied claw. And I got no satisfaction from saying "I told you so!"
(Fortunately, all the other vets have been really good).
