You are fully entitled in this instance to feel saintly and self-righteous. Taking in an abandoned animal is one of the most generous and beautiful gestures a human can make. Once you've done it, you'll never buy another breeder dog again. And for those who hesitate to adopt for fear of "what they'll get", I would point out that no dog is guaranteed. I know people who've bought a purebred puppy that grew up to be unruly or aggressive. Sometimes a rescue pet who's lived with a foster is more predictable, as they've been observed over a period of time by the family.
