Did a quick web search, found the Precious Little Paws website:

Again, I have no experience with these breeders, but here are a few things that stood out to me that are typically considered to be "red flags" in regards to breeding: 
*  They are breeding multiple breeds and mixed breed dogs.  Opinions vary, but for me, that alone would be a deal breaker.  Purposely crossing breeds to create and sell mutts is NOT a responsible breeding practice.
*  Breeding non-standard dogs
*  I personally don't agree with any breeder who takes deposits or orders over the internet for dogs and ships them out like cargo, no questions asked.  IMO, good breeders CARE about the homes their dogs are going to. They are selective with new owners and meet them first.
*  They send pups to their new homes at 8 weeks--WAY to young to be separated from mom and litter mates.
* The health guarantee only covers health defects that are life threatening.  There are loads of genetic health issues that can occur that aren't life threatening, but avoidable and costly to the owner.
*  And it doesn't look like they care one way or the other if the dog is ever spayed/neutered.  

  Personal opinion, keep looking.
