i love to own a Golden Retriever...

Now I don't say I agree with this. I have purebred dogs and they were bought from responsible breeders, because showing purebred dogs is my hobby and passion. Buying from pet stores is always a bad idea, but buying a puppy from a responsible breeder can be a rewarding experience as the good ones are there for you for the lifetime of the puppy, always ready to offer advice, take your dog in for boarding if you're on vacation or to help you out with behavioral issues. They also do appropriate health testing for your breed to ensure your puppy is healthy and long-lived. As a former rescue coordinator, I know that 3/4 of the dogs that come through rescue were either bought from backyard breeders (breeders looking to cash in and make a buck off a breed's popularity with no regard for health testing or breeding for the betterment of the breed) or pet stores where the former owners thought little 'Rex' looked so cute in the window of the store and had to 'rescue' him from living in a small glass cage. Puppies from responsible breeders rarely, if ever, end up in rescues or shelters (and if it is, it's not for long) because they are almost always willing to take the dog back, regardless of age, to either rehome or live out their life where they were born. They don't want any of their 'babies' to end up in a bad situation, and usually do rigorous interview processes with prospective puppy owners just to prevent that. Granted, there are too many homeless animals in shelters, but few are actually purebreds, too many are the result of people not spaying and neutering their pets and having 'Oops' litters. The blame lies in the hands of pet owners across the world for not having their animal altered when they should be.
