In the last few hours my Whippet has been chewing, licking and biting his back paw. He keeps dragging it across the carpet and kicking out with his hind leg. Something is clearly irritating him, I've had a look at the offending paw and cannot see anything.
He cannot sit down and relax for a minute and is pacing around kicking out and rubbing himself long the floor.
Any ideas of what I can do to help him settle?
