i'm sorryt his happened to you
man, this makes me very sad!!!
but glad to know your puppy is doing better...
when you go for your 6 week check up, i highly suggest bringing your puppy's poop from either the night before or the morning of and put it in a zip lock bag and bring it to the vet for the stool testing...
please update us on how the little one's doing!
*lots of love to both*
