in most cases the buyer never listens to breeder and insist they can handle the reasons you're telling them it's not a good match.
yes, in any form of selling/rehoming dogs and horses you get the same thing. I sold a horse to a lady who had total, blunt accounts right from me of how the horse acted and why he wasn't suited to her. I spent half an hour trying my best to talk her out of it, listing every flaw. This was an experienced horse person! Low and behold, it didn't work out. Just like the person who goes and adopts "princess" from the shelter and, after being told she has a high prey drive, high energy and doesn't do well with cats, they take her home, don't walk her, and are appalled when she eats the couch, the guinea pig and the neighbors cat.
People don't listen. They get an idea in their head, put the blinders on and face the consequences later.
