Dear buyer, I have visited a few websites of people selling Labradoodles in my state, and neighboring state's. What I have noticed will hopefully help you in your search for a physically, and emotionally healthy puppy. Obviously, this is what you are trying to do, you found my site, and I hope this information will help you.
False Pedigree's -- I've noticed several pet shops or back yard breeders noting "Australian Labradoodle" puppies with Pedigrees (family linage), I believe the Pedigree certificate is copied off the internet. How do you check this out? The parents of the puppy should have DNA numbers through Pawprints or Optima genetics & your puppy should be related to these parents through microchip& DNA registration numbers. DNA your puppy to see if its a match to the parents. I'm sure you can think of other ways too, like contacting the owners on the certificate. An easier way would buying your A-Labradoodle from an established Labradoodle breed association.
False Health Testings -- Health testings should come from established Labs; OFA; Penn Hip; Paw prints genetic's; Mars genetic's, and stay away from The Dr. so & so health testings. I'm sure there are several reputable company's, ask a vet to help you, and ask for COPIES of all health testings. I think this is one of the biggest "scam" areas.
Read the information before putting a deposit on a puppy! Check out the paperwork, have a contract, and make an informed decision. Notice, how many breeding dogs the person owns, and are there more than one type of breed(potential puppy mill).
