I took my little Shelby (one year old now) for a run yesterday. I ride my mountain bike and she trots along and then we do a few short bursts of running. Anyway, she started limping right as we got home and wouldn't let me look at her paw. Finally today while she was sleeping, I looked at it with a flashlight and it looks like there is about a 1/4 circle of pad "skin" that is gone. Looks kinda like a blister that has had the blister part torn off exposing the tender skin. She is not whimpering, just favoring her left foot a bit. Not sure what i can do to make it better or just wait it out. Anything I try to put on it I am sure she will chew/lick off.
