The question is, vomitted on what? Fill us in eh??
My best dog puke story is my friend whose labbie chowed down on some rotten (read reeeeaaally rotten, as in heading toward the toothpaste in a slimy skin stage). Dog walks next to the Skeena River during salmon spawning season turned out to be a bad choice. The dog kept it down until they were headed home in the SUV, during which ride all of the salmon paste was deposited on the back seat surface. The smell in the SUV was never the same again, in spite of rather impressive effort, as well as lots of years. It still stank when given to a young relative about ten years later.
