Noticed my dog Harley limping this morning when I fed them. Then noticed the blood trail. Uhmm - officially not good. Checked him out and found that he had torn a nail to where it was hanging right at the base of his paw. After looking at it a bit I could tell it was a pretty significant injury, so I called the vet. No worries - only a $300 vet bill. Wow. They had to put him under and perform minor surgery. Nice. Kind of funny watching him flop his paw around with a baggy on it tonight though.
