This is what can happen when you attempt to love that big dog. A rub of the tummy has him stretching out like a cat and being that the gentle giant knows not his own strength, this is what happened when he accidently popped Jake in the mouth with his paw. The teeth have been loose for more than two months now and stubbornly refused to let go. Enter Dr. Gimli, Dentist. The Tooth Fairy paid well for these, I'm told.
