My dogs are walked on the beach every day but I do clean up after them, and they don’t tend to bite anyone. The collies just chase a ball and the sheltie is constantly on the lookout for rancid dead things to scoff (fish, seals, birds - she’s not fussy).
I don’t think water meters are common or really encouraged up here as far as I can tell. Rains so much they have to use all that water somehow I guess
