"When somebody is "like a dog with a bone," it means they are very persistent and refuse to let go of something. Like a dog who won't let go of a bone, no matter what. It's usually used to describe someone who is stubborn or fixated on a topic or goal, and won't give up until they achieve it, like a dog who keeps chewing on a bone until they have stripped it down to nothing."
