My sister got a dilute Lab last year. Before the poor pup was 6 mos., multiple vet trips revealed that it's a train wreck of crippling dysplasia and autoimmune problems. She tried to contact the breeder (who claimed to have a health guarantee) and found the website down and phone disconnected, but did find others with similar problems doing an internet search. Sadly, I believe her experience is the norm. Most of the general pet buying public has no idea of how to look up hips, elbows and clearances on OFA and sadly, believe websites where charlatans claim their dogs have "cleared" hips, etc. For this reason, I harbor a special animosity toward lying frauds who produce animals destined to live pain-filled lives.
