Hi Fran27...
I wasn't planning to revisit this issue here, but I wanted to say that many of us at that "other" site are well aware of the issues of BYBs and the need for health testing. I actually managed vet clinics for over a decade, and we counted many breeders among our clients. I'm not a huge supporter of cross-bred dogs (and have discussed this with the OP on another forum) - but there are people out there who do not want a purebred dog, do not want to adopt from a shelter, and want those puggles and labradoodles and what have you. I'd rather see them buy them from someone like the OP (who meets every client individually, is very cautious about who she sells to, and who follows up with the new owners) as opposed to buying from the lady who sells cross-bred pups from the back of her van at my local Wal-Mart parking lot and her check of her clients consists of whether or not they can produce the cash on the spot(and yes, I've seen this happen). I also know that not all breeders who sell pure-breds have their animals health tested or breed for the purpose they should - some also breed purely for profit and while they tell puppy buyers they do all the tests they do none.
As for the OP deleting entries from her personal guest book - it seems to me that is completely up to her as it is her personal website and she can do with it as she sees fit.
It's not a perfect world, and yes, I would like to see people buy dogs either from registered breeders or adopt from shelters - but while we can educate people we also cannot dictate what they can do. If they have the facts and still choose to buy a puggle or labradoodle I think I can respect that (although if they then experience health issues or other issues my compassion may be somewhat less, LOL). I think there are BYBs who truly do love their dogs, their puppies, and who are sought out by buyers, even by educated buyers. This then becomes the decision of the buyer, and not up to me to control or dictate.
And I agree with Meggie - i'd sort of hoped this issue had been addressed and dropped....
