Or possibly a by-law.
George and I did our multi-terrain walk today: up through the woods, across the top into Clyne Park and down to the front before finishing off with a tiny stretch of beach.
And therein lies the problem. Strictly speaking I don't think we should have been on the beach.
From May 1st to 30th September dogs aren't allowed on a number of beaches in Swansea and Gower. I have no problem with that as a general rule; dogs and families on beaches don't go together. Dogs pee on children's sandcastles (at best - at worst on people's rucksacks); dogs don't see why they can't join in picnics; and dogs can be big, bouncy and over-friendly, which upsets some people.
But it was Monday morning, not in school holidays, the beach,which is never that popular with families because the tide goes a long long way out, was deserted, and I am a responsible dog-owner. I clear up poo and would put George on a lead if there was the slightest suggestion of him being a nuisance. And we were only walking a very short distance along a long beach.
So why did I feel so guilty?!
