A Backyard Breeder is an amateur animal breeder. While some may have good intentions, in most cases the conditions are considered substandard, with little to no emphasis on ethical or selective breeding, or provide proper care for the well-being of the animals they are breeding.
Why are backyard breeders bad?
They pay little or no attention to genetic health issues in both the parents and the puppies. They often charge less money for the puppies than a responsible breeder, but still more money than they should (no one should pay for puppies that were bred carelessly). ... Never trust a breeder who won't guarantee the puppies.
Is it bad to get a dog from a backyard breeder?
