welcome to YT! You will find lots of support here.
This is such an unfortunate story. I am soooo sorry for your loss. Those poor grandbabies!! I had a death in the family 2 years ago and I was floored. I was 25. I can't imagine dealing with that kinda loss as a
child.

I wish them the best and hope that the healing starts soon.
As for the puppy, I really really hate these bad breeders. I'm so sorry you came across one... but I am glad you are doing everything for the health of the new puppy
once again, welcome
