Whether these businesses are profit-driven puppy mills or well-intentioned backyard breeders, they can still produce poorly bred dogs with health and behavioral problems.
While there are exceptions, most puppy mills provide their animals with substandard care, the result of keeping so many dogs in one location.
Because they are bred indiscriminately for mass production and profit, the puppies from puppy mills often have severe congenital defects and serious health problems.
One thing is obvious, there is a world of difference between backyard breeders and puppy mills.
Avoid Puppy Mills - disreputable breeding farms that mistreat animals by confining them in inadequate kennels, under poor conditions just to create additional litters.
