This business is a front for bad breeders. They offer known mills a means to unload puppies.
Our mini had kennel cough, worms, was under weight and came from a known puppy mill (recovered breeder's name from ACA paperwork). She was signed over to this company a day before we picked her up.
It is unfortunate that such entities are allowed to exist, considering the bad breeding practices they allow to continue.
If you are going to get a puppy/dog, consider a rescue dog, an SPCA dog, or a dog from a high kill shelter... don't feed this monster!
