That's it... Nice clean sand pit, family of five (baby through to school age) playing in it, their large dog running in and out. No attempt to stop it, then it pees in the sand next to one of the diggers. Not a word from any of the family. Aibu in thinking this is out if order or am I being uptight? Couldn't believe they thought it was ok to even let the dog in the sand, but no-one seemed to object.
