I brought Riggs to the tennis court at lunch to play fetch and get his and Ruby's nails worn down a bit. He quicked 11 nails. even his dew claws. I didn't realize it until the third or fourth throw
I feel really bad, but he didn't even notice and still wanted to play. We moved to the long grassy strip on the edge of the court. I eventually gave him one ball and left the other one with him as well. It's an automatic babysitter because he can't decide which one to chew on and lays on one while he chews the other. When I get ready to take one away he clamps down on the one in his mouth and covers the other one with both paws and holds on. It's really funny.
And of course, Ruby's nails hardly got touched at all. It takes about 10 throws until she really starts chasing him around but I didn't want to keep him running and bleeding everywhere.
