Oh, how very sad
. I know you must be hartbroken. Was the mother stimulating them to go to the bathroom? Maybe they needed to be tube fed. Had you taken them to the vet? There are many things that could have been going on. However, sometimes these things just happen and that is what a vet will tell you. Did they get bloated before they got worse? I know this is all jumbled. How is your surviving puppy doing? Again, I am truly sorry that you lost 2 of your little puppies, my heart goes out to you.
