I've had labradors they are really wonderful
that breeder at first glance looks good, Im in Europe so I have never heard of them but they show and hunt which is very good, check the eyes and joints which are basic health tests and they have very few breeding dogs. Those are the first thing you look for. They also seem to care greatly where the puppies go so thats good as well.
just a few things if you decide to call them.
1. Make sure that the litter comes from health tested parents and that the joints are checked annually.
2. Also that the Parents at least one have had some success in the show ring they seemed to have rather young dogs some are not finished. This is important because it does raise the question whether they are showing to improve the breed or as an advertisement.
3. Ask how often they breed, bitches should not be bred more than three times during their lifetime and not before they are 2 years old and not later than 7 years old.
4. ask about the COI% (co-efficience of inbreeding) it means how related the parents are find the average for the breed (quick google search) and it really shouldn't be much higher than that in my opinion.
5. Ask about bloat in the line and other common labrador deseases that there are no genetic tests for
