Our baby girl boxer, Bella, is Zeus' biggest fan (and biggest tormenter!) She absolutely adores him, hence using him as a seat. I am not 100% about Zeus in the water. He fell in our neighbor's pool and just sank; didn't even TRY to swim but yet when we took him to the creek he jumped in and swam ashore. I think he *can*, but possibly was just too lazy when he fell in the pool. I would like to get him more comfortable swimming though!
