A lot of "Labs" at the pound are mixes, and you don't know with what. The Rescue dogs are vetted and fostered with families, so at least you know what you're getting. They also are treated if they have heartworm, etc.
Thanks so much for the links; I''ll check those out now.
In defense of the pound dog: yes, many are mixes, but many of those mixes are very kind, trainable, and lead longer lives than our purebred dogs.
If you have your heart set on a particular look, then breed rescue is the way to go. But the mutts at the pound face death if people don't save them, and there are many hearts there worthy of a good home. It may be the size and shape you are looking for, or you could find yourself looking into the eyes of a shaggy dog you never would have predicted you'd fall in love with. I love a big dog, but one of my rescued mutts, Zulu, a cocker mix, was my soul-mate and a dog in a class by herself. Good dogs have many shapes, and are good despite their less-than-accredited breeding.
I am a fan of the purebred dog, don't get me wrong. I used to compete and hunt with a purebred lab. But most people aren't interested in competing or hunting or promoting the improvement of the labrador breed, they just want a pet. Mutts make great pets.
