Some sums for you:
Puppy + sunshine + 4 kids + beach = loads of fun.
Wet puppy + a surprise jump by said puppy onto tummy of sunbathing lady = yikes! and "So sorry!"
Wet puppy + a surprise jump by said puppy onto tummy of sunbathing lady who turns out to like wet puppies = smiles from her and relief from me!
Incidentally, it may surprise you to know (it still surprises me) that I once flew a helicopter above this very beach. (I got a lesson for a special birthday and, yes, it had dual controls). I had to follow the course of the river, and it's a very bendy river indeed so that wasn't easy.
