Angel, according to what little the shelter knew of her, was breeder stock: that is, she'd been caged for life, pumping out puppies, and then discarded when she was no longer useful. She spent one winter's night at the shelter—in the back of an unheated van from which she couldn't be coaxed.
Angel needed to have quite a number of her teeth removed, and maintaining the few she still has requires constant attention. Her expenses mounted to $850.22 in her first six months out of the shelter—just in unexpected medical and dental services.
We know nothing about Casey's history at all. In his time at the shelter, he enjoyed playing with the other dogs but definitely hungered for human companionship.
He's a delight to be with. He loves to play and wrestle, and he keeps the others young. Even though he was in great health, if a bit overweight, his first four months' care still cost $484.07.
