You think he'd just drive him to Canada and have him euthanized, like what people do when they realize they can't afford the cancer treatment for their dog/cat, and they have to choose that route?
Edit: Even better, you'd think we'd get graced with a retarded Facebook post afterwards? One along the lines of Clint stating he was taking Cobes to the dentist and when they got there, Cobra ran away into the night, and he's been missing ever since. The family thinks he probably burrowed into the ground for winter and will back in the summer when the ground warms up.
