Claire, two of our corgis chewed their paws. Turned out they had seasonal allergies. Check with your vet. I would only have to give them a pill once a day in the spring and fall. Does she shake her head like her ears itch? Good luck.
Maura has allergies. She takes a pill too, and has anti-itch spray. Nope she doesn`t shake her head. She is doing better!
