His right iliopsoas (groin) again, the same one as two years ago. Rehab that time took five months. I am just absolutely devastated. He is such a good dog, and such an active dog, and now our summer is crate rest and five minute leash walks and rehab exercises instead of hiking and swimming and frisbee and agility and flyball. I am just sick about this. He's as fit as I can make him. I am so scared that it's going to keep happening again and again and again.
