I agree. If you're looking for a family pet, please try the local pounds first. They have some really good dogs/cats that need loving homes.
For me personally, I choose pure breds. Mainly because of the dogs we raise and breed. But if you're just wanting a family pet, the pound is definately the best place to go.
Has any one ever noticed the people selling dogs at Walmart? I made the mistake of getting one there. It turned out many of the dogs had kennel cough and were sick. They come from out of town. Luckly my dog is ok but others said there's got really sick
