My chocolate lab Shadow has a natural affinity to water which seemed to kick in aotomatically. I saw on one of the forums a question from someone asking how to introduce their lab to water. I have the opposite situation, shadow loves water so much so that instead of merely drinking from the swimming pool, he actually wades down onto the steps and sometimes goes for a swim all by himself. If I or my daughter are in the pool, he will attempt to rescue us by "gently" holding our arm in his mouth and pulling us back to the steps. This is all very endearing but when we are trying to do laps in the pool it is a bit distracting. Our pool is close to the kitchen door so every time he takes a plunge we have to close the kitchen door and ban him from the house until he dries off.
