We got a Kayak from amazon that was doggy friendly. First, we got him to learn to go on the boat in the house. We say boat, and point, he jumps inside. Such a smart puppy! Once he consistently got the "boat" command, we took him on his first ride down the river. We went to Wekiva Island today and he did beautifully. We also got him the outward hound lifejacket in Large.
