I have not, but based on their website, I would recommend looking elsewhere. They have red flags all over the place. First and foremost being that they breed various different types of dogs (including mix breeds), which no reputable breeder would ever do. This screams of a broker and/or puppy mill.
Note - Arkansas doesn't have a lot of AKC reputable breeders, but is very much covered in byb's and puppy mills.
If you are looking for a true love - a Yorkie that will be your baby for a long time, I highly recommend browsing the recommended breeders (listed by state) on the YTCA website here:
