You can find dog breeders by the hundreds in every city, but not all are licensed, responsible, or even fond of anything else apart from making big bucks.
If your chosen breeder doesn’t have any available puppies, only offers waiting lists and asks for deposits before the puppy is born, chances are you may be scammed.
Instead of buying or adopting from a breeder that has no reviews from customers, look for a breeder that has good reviews of customer adoption experience with pictures of the adopted puppies.
