I've seen different nail lengths on dogs and have been wondering what is best. My cousin's dogs have these little nails that are filed by the pavement (they love to run outside). My roommate's dog has extremely long nails in comparison to my cousin's dogs. I'm attaching a picture of the long nails, they're 1.5 cm or a little more than .5 in. His nails really scratch when he's jumping up to be picked up and I'm wearing shorts.
What should be the proper length for nails?
Sorry for the poor quality pic! I took it with my phone.
