Stress would make anyone - dog or human - want to leave a situation.
But the behavior could also be attributed to nesting, Jonathan Klein, owner of I Said Sit dog training school in Los Angeles, told The Dodo.
"Almost like a squirrel that stores away food, except that most dogs don't save it, they eat it right away," Klein said.
Your dog could also simply have a problem with the bowl.
"If you're feeding your dog from a metal bowl, it's possible that the clinking sound created by food being pushed around, or a dangling collar tag, may be irritating or upsetting your dog," Dr. Holly Ahlgrim of DoveLewis Emergency Animal Hospital in Portland, Oregon, told The Dodo. "They may be chewing their food away from the bowl to avoid the sound."
