I just took a quick look at their website.
They're willing to ship puppies once they're 8 weeks old?!?! Yorkies need to stay with their mothers until they're AT LEAST 12 weeks old. 8 weeks is way too early to let them leave home and certainly too young to ship.
They breed several other breeds besides yorkies, another big red flag for me.
And there is virtually NO health guarantee at all - none at all if you don't take the puppy to the vet during the first 24 hours. Some congenital problems won't even show up for months.
I didn't see any mention of the dams and sires, only pictures and prices of puppies for sale.
That's what I found in just glancing at the site but it's enough to make me run in the other direction!!
Good luck with your new baby.
