Big Sigh of Relief! X-rays and vet exam show the cracker (who's been nursing a back leg owie for weeks) does NOT have a torn cruciate ligament, nor does he have arthritis, bone cancer or any bone fragmentation. Whatever Loki's doing to his back leg via his banana-head zoomies, is muscular. Rehab at Sage Veterinary Physical Therapy is already scheduled. Jill is ready to give him lots of physical torture, err, I mean therapy. Boo-wa-ha-ha-ha. The Whole Pet Vets claim he was a very polite and gentle boy the entire time. I guess I'm the only one who brings out the cracker in him.
