Thump, thump, thump, thump, thump! There goes that leg again. Champ, champ, champ, and there your dog goes again biting their paws. They have been at it for days. Their skin is inflamed, red, and seems to be maddeningly itchy. You can tell the poor pup is miserable and it is time to do something about it. Your dog and your sleep will thank you.
