My boy, Ranger. He's not the "smartest dog on the planet", but responds well to a lot of commands, and has a good repertoire of tricks that result in him getting snacks. He's of the opinion that anyone driving a delivery truck (mail, UPS, Amazon, etc) is a threat to his domain. Overall, he's a pretty darn good dog.Here is our Rosie. She is a Cavapoo and possible the smartest dog on the planet. Ok, so I exaggerate at times. Rosie can do all kinds of commands. Our neighbors constantly ask if I can train their dogs because they are amazed by her.
