When your pet, usually a dog but not limited to dogs, follows you around to areas with food (kitchen, dinner table etc.) in hopes that a scrap of food will be dropped for their consumption.
Every time I’m in the kitchen, that dog follows me in crumb sharking around hoping for a treat.
A pet, most often a dog, but possibly a cat, bird, ferret etc, who follows you into the kitchen or when you’re eating hoping that you will drop scraps of food that they can eat.
Every time I make breakfast my crumb shark of a dog stands between me and the stove hoping I drop some food.
