My Chihuahua is my best kayak buddy. I strap a body board to the front of my kayak so he has a place to hang out. I started slow in flat water until he got used to it and now he loves to go.
His name is Guinness (after my favorite beer)! I guess Chihuahuas make good paddling partners. Guinness loves paddling with me and is very well behaved on the kayak (except when he sees ducks). Looks like your little guy loves paddling too!
