I don't know of this breeder so I have no first hand knowledge of them. But here are some things that jump out at me from the website:
Primarily, they don't show ANY of the adults and how many different breeds they have. Secondly, that whole sales contract is a little...no, VERY..shady, IMO. Particularly this part
"we will allow a $50.00 discount for the following: Cherry eye, hernia, joint, knee or hip defects, and eye or ear defects. After this period No adjustments will be made"....what?!?! This is something that as a breeder you should check BEFORE hand, not "oh we'll give you some $$ back if the dog has this!"
