You have all my sympathy
& I'm surprised your post is so restrained when you've just been treated so badly today
IMO the 'breeder' has done you a favour as I don't think they are honest, sincere or reliable to be able to do that to anyone.......that pup was obviously not meant to be & your new little pup is out there somewhere & I'm sure you'll find each other soon
(little consolation to your kids I know
)
(when buying my eldest her 1st car, a few years ago, we drove over 21/2 hours to collect it (after checking all was well, before leaving!) only to get there & be caught in the middle of a family domestic & was told that the car wasn't for sale & the DD had done it to spite her mum
I cried all the way home.....but a few days later we found her a car locally, which was so much better than the other one)
......all will turn out well, you'll see
