We daily try to have Royal practice walking in or on something new, starting with a somewhat unsteady surface with a novel texture:
Because I like having dogs that enjoy to swim - it is good fitness, a good way to cool down on a hot run, and I find it fun to play around in the water with them - we are also working daily on getting Royal to enjoy water. We first rewarded him for getting in and out of an empty wading pool, until he loved charging in there to make good treats happen. Then every day we began adding a bit more water. He makes the choice to get in, but since we have built a lot of value for the pool by associating it with good things, he hops in and out multiple times a day. He currently is getting in and out of water about elbow deep.
