OP, I hope your pup is doing well.

I like to have documentation before feeding any non food items. I can't find any on this topic of using cotton, but perhaps I am missing it.

Do what you think is best for your pups in consultation with your vet. Nobody has to prove anything. On the other side of that, if it is not scientifically proven or standard practice I just don't go that way for my dogs. I use the methd in my post above. If there are any serious concerns my vet would scope.

My dog used to eat pieces of blanket and underwear. It was not always a pretty site. ?vomiting up fabric to needing an enema for removal of blanket pueces.. I would not purposely give him cotton... All I can say is my vet (has worked er relief at several places) would not be happy if I fed my dogs cotton. But to each their own.
