Why would a reputable breeder ever give one of the pups have worked so hard on to a pet store? A reputable breeder raised dogs in their home and loves every one. They personally search for the right home for each dog. Why would someone give up a pup to go live in a cage at a petstore and have no say in who the dog will end up with?

If you researched the breeder yourself why couldn't you just go to them and get your dog?

And as others have said, the idea you are saving a dog, although your heart is in the right place is just wrong. All you are doing is creating one more empty cage to be filled at a store, making more demand at the mill to have some poor bitch who has spent her whole life in a tiny cage need to create another puppy.

Personally, I do not ever even go in stores that sell puppies. I can't look at them and not cry... or scream.
