Congrats, on the litter, but just curious.
I've seen a few litters on here supposedly posted just for fun, to show puppy pictures. But there is a link to the breeder's website under the signature, and this forum is excellent for marketing, a very targeted audience. A marketers dream, really.
I think one breeder sold quite a few of her pups to forum members, using a similar "look at this amazing litter", strategy, and also having posted videos of the parents working, training, being pretty, etc.
Seems a bit tricky, to me, treading the line between free advertisement and just-for-fun puppy photos.
I get why the OP is doing it, and I don't see anything really wrong with it, personally, but, it does seem to cross the advertising line, to me.
