I had a litter of puppies and this one was the runt. I work for a vet and always took the extra time and care she needed at any cost at work. She was tiny but her new owner begged me to let her go home last week so i let her

( MY BIGGEST REGRET). I knew I should of kept her. Please no one bash me for this. She went home on monday, dec 16th and was completely fine. Last night the owner told me she threw up bile so I gave her instructions directly from my boss ( a vet) and she said she did everything. She said that seemed to help and then a few hours later she threw up bile again, got weak and passed. She was 11 weeks old. My little Jaden is no longer on this earth and I have been sobbing for hours with questions unanswered. I just don't understand what went wrong.
