My parents always advised me never to buy a used car, because I would just be buying “somebody else’s problems.” Unfortunately, that’s how some people view rescue dogs-as dogs that weren’t wanted because they had problems and didn’t make good pets. Most of the time rescue dogs are purchased by people not thinking about the time, effort, and expense involved in keeping a dog. These dogs end up in shelters, or along the side of the road, or, if they’re lucky, in rescue.
