Dog Fish?

I took our dog for a walk in the park on such a beautiful day.
There I bumped into a lady I knew years ago, we used to pass the time of day, chat etc. She used to work in the local Corner shop.
This is her dog having a dip in the pond, she kept telling her it wasn't the place to swim, but her dog didn't listen. She has such a lovely expression on her face don't you think. She's loving it :)
