If your possible future puppy is to be a family pet and family pet only, I don't understand why having endorsements on the registration matters to you. Why does it? Do you plan to breed without the breeder etc knowing? Do you plan to cross breed it? If so, why? (Although I have my own guesses there). I'm just curious really.
If it was me, I would be really pleased the breeder had endorsements on their pups and vetted potential homes and people very carefully. If only more breeders did so.
Too many people breeding too many dogs from unhealth-tested, unregistered and, quite frankly, unsuitable dogs whether that be in temperament or otherwise. And don't even get me started on cross-breeding purely to make a few quid and supply the pet market with thier "designer dogs" with ridiculous names. Believe it or not, they aren't new or rare breeds, they are mongrels! Loads of them in rescues everywhere.
Don't get me wrong, I love my crosses - I have a lovely one - but they will always be rescues.
How long have you wanted a Basenji for?
I've been longing for a Basenji for a few years now but the time and situation isn't right, so I get my 'fix' from other peoples just now, as mad as that sounds!
