Welcome to the board.. 
Sorry your visit was not such a good experience.. even though the people were very nice. Most breeders that are not really good are extremely nice .. try to sell the puppies ofcourse..
As i read your story about the dogs didnt look good..
I wouldn't take a puppy from there..
You never know ofcourse. even though you get a puppy from a very good breeder, there is always a risk that the puppy can get sick ... you cant have 100% garantueed..
But you can mostly hear from people who got puppies from the same breeder that they r good or bad.. or so so..
I think f you really care about the mom and the puppies,. you take care of them very well.
Including the hair..
Maybe if you look around the board you can also ask a question if someone knows a good breeder around your area...
Its just an suggestion;
Good luck and relax..
You find your baby soon i think.
Love Priscilla and Snickers
