Glad Mia came out of it ok, Megan was diagnosed with PDA, otherwise know as blue baby syndrome in humans. We opted not to have the operation as I didn't have $2500 16 years ago, she wasn't supposed to live out her first year, she was 15 last may when I had to put her down, she was a fighter and a sweet girl.
As to the question of the puppy, is there any chance your vet can check it out before you decide to adopt. I don't know about you, but I like and trust my vet very much, and would feel better about having my own vet check the puppy out, also get a health guarantee from the breeder, and I'd make sure it was for two years just to be sure. Good luck in what ever you decide to do.
Cheers Quad & Gina
