Bear just turned one last weekend and this was his first river trip. Would not stay out of the water which I expected because he sits on the grass at home when the sprinklers are on. We were tossing the ball in the water from the shore for him and he would leap into the water every time. The kids next to us ask if he could jump off the dock and I had no idea if he would or not. So when the area was clear I took him and his Frisbee to the dock and off he went. Didn't even hesitate.
