The other day I noticed this dog, on a house boat, having what looked like stomach cramps and making sounds as if it was trying to throw up. After a few minutes it finally threw up this sticky yellow gunk, looked like melted cheddar cheese. I felt really sorry for the it, not knowing if it's normal for dogs to throw up yellow gunk because I've never had one, so I tried to knock on the door to get a hold of the owner, without luck. After some time the dog seemed fine, and I went home.
