What desirable behaviors did your dog pick up naturally?

I have two beagle mixes, so, they naturally want to smell EVERYTHING on walks. With my one year old mix, I am able to just say, "Let's go" and she will immediately move on. I didn't specifically train her to do this, she just does... I'm surprised and happy that she does because many beagles ears turn off when they catch a scent. Additionally, like your Louie, she knows "this way". She doesn't even need to turn to see where I am going, she just turns in the way of my voice.
