I'm not in the show or breeder world but would hesitate to even believe someone would sell a puppy using the words 'show prospect'. From what I understand most show breeders hold on to those puppies & if they do sell them ..it's usually when they're a bit older.
But if as a breeder, you (or whoever), knows in your heart that the buyer is due some compensation - I say for good business purposes...offer it.
I hesitate to even say this because I notice many of your posts are directed towars certain people here so I want to clarify - this is ONLY an opinion....We all know it's not a perfect world and money is a big motivator in puppy sales.....it's a shame it isn't more about ethics. If it were - I don't think we'd be seeing so many sick little yorkies

(not meaning this thread ...that was just a general statement)
