A few things I noticed on the breeders' website:
--They specifically state that LP is not covered by their health guarantee.

--They are breeding "designer dogs"

--They seem to have multiple breeds, Yorkie, Parti Yorkies, Maltese, Chis, a Rat Terrier and the "designer breeds"
--Judging by the birthdates of the available puppies, they seem to have had LOTS of litters in a very short time frame--4/12, 5/10, 5/11, 5/13, 6/12, 6/22. (3 litters in 3 days!?

)
--They seem to place their puppies at an age much younger than what is commonly recommended--8 weeks?
--They have advertisements all over the web including some for 'teacup Chis'..I'm pretty sure there is no such thing.
--Like someone already mentioned, the no questions asked shipping of young pups all over the country doesn't leave a warm fuzzy feeling.
Just my observations and opinion, but a few too many red flags for me. I'd have to pass on this
"breeder."
