A Reincarnated Beagle's Daily Life of Taking Things Apart and Putting Them Back Together

Any Really Satisfying Novels with a Protagonist Like a Beagle?

I want a protagonist who goes completely off the rails at the slightest provocation and does whatever they want without a care in the world. Something incredibly satisfying. I've read too many protagonists bound by rules, so I want something different, someone who does whatever they please.
