The fear phase after the Goose incident didn't last long. Kody led me back to the scene of the crime to sniff around and then on a long adventure walk today. He saw two dogs and barked mildly once and really just wanted to watch them.
Since the walk he's been a wild dog wanting to go outside to collect pine cones (a game we play) and sprinting all over the house with wild abandon. He's even getting excited about getting his teeth brushed which right now is just me touching his back teeth with my finger and then giving him a treat. We'll add the toothbrush later.
