LOL You make me feel better. We had a fire in the chimenia about a month ago. I toasted a few marshmellow and the dog ate some with me too.My dog used to eat marshmallows with us all the time.
We would do 'smores and he would get a lot of marshmallows and graham crackers.
He was funny to watch since the marshmallows were warm and sticky.
I had a dog that would absolutely drool and go crazy for the ears off marshmallow peep bunnies; one of her favorite treats. You don't mention the weight of your dog, or the size bag. You could ring the on-call vet or after-hours clinic in your town, but marshmallows are basically sugar and gelatin--nothing toxic. I would expect some digestive issues like you said since the tummy is sensitive. I think the biggest issue would be a choking hazard, but if they've been eaten, this isn't a problem at this point.
I just googled this and your question and thread came up.![]()
He is a goldendoodle, weighs about 42 lbs. The bag was the normal size bag of the big marshmallows, but I had already used about half of them.
So far he hasn't acted odd at all...I should mention he is already on meds (prednisone and antibiotic) to treat a hot spot on his tail that got a little out of control. So he has been pretty subdued this past week.
Watch him on the Prednisone. It makes some dogs have voracious appetites. He may try to get into other foods.
