What I found in 5 minutes after searching for that kennel/breeder name. "2-3 new litters per month" and puppies for sale on craigslist, ebay, and others on adopt a pet type sites. At least one new ad uses the same picture of a puppy from an old ad. None give any info on pedigree or parents. The ebay ad I saw listed age as "baby". Most ads are $600, one had $400, but they had one for $300 that was said to be the only surviving puppy from a litter so they were not registering it with AKC. That makes no sense, so I would wonder what is really up with that one. If your buying one for $300, it is likely that puppy and why they will not give you the pedigree. Then there was another for 6 wk old Black Labrador puppies without papers for $200 each and the one pictured is older than that. All they ever advertise is that the parents can be seen on site. This smells of puppy mill IMHO. If your buying without knowing the pedigree and no health clearances on the line, you could be taking a risk considering how the risk of things like PRA and Hip Displasia can be greatly reduced if you do have health clearances. Especially important for you since you mentioned in a prior post your concerns about your last Lab not being as long lived as other labs you have known. Genetics are as important as nutrition, if not more.
Hope you don't mind me posting this John, in case someone looks later. Good detective work should be shared
