A few Christmases ago, our Golden helped himself to a whole bag of Hershey Kisses, which he devoured foil wrappers and all. We called animal poison control, who instructed us on how to induce him to vomit. He was fine although he pooped red and green foil for a few days.
Might have been healthier for him than a big mac
Festive! But maybe not something you want as a tradition I suppose!
That sounds very much like our cat after consuming some tinsel from the tree. Her poop was strung together on the strands for a day or two until it finally cleared out of her gut. It drove her nuts.
