Sunshine means Swimming - Doesn't it?

Normally I can't keep Winston out of water - or perhaps more accurately - watery mud pits. So imagine my surprise when I threw a toy into this small 'dog pond' and this happened...



He did paddle the water a bit, but just refused to dive in. So, defying everything everyone says about dogs not being able to reason, he wanders round a bit, and finds a stepping stone.




Where he starts paddling again...



Loses his balance...



And falls in...




Proving he can swim after all, and finally wins the prize and retrieves his toy!
