I don't know anyone that has used them. I did go check out their website and call me picky but a couple things stand out. 1. She has standard listed as 5-10 lbs. Standard is usually 5-7 lbs. At least that's what I've always read. 2. She has small listed as under 5lbs. Most reputable breeders usually try to breed to standard 5-7lbs. and don't look to breed tinys (under 5lbs.) on purpose. Not saying she is but she is advertising 5 and under pups. Also, you can guestamate the size a pup will be as an adult but you can't guarantee it. 3 rd. and last it kind of bothers me that she advertises that she usually has puppies available. I don't see many reputable breeders with pups always available. I may be being picky. Maybe others will have better input. Elaine |
