That's a shame that people just don't care enough to pack a poo bag. We are never without one, although Molly's poo is the size of a half a pinky finger. lol.
Yeah she's a snub but I've grown to expect it! hehe. Glad you had a nice beach day. Too dang cold for the beach here, plus the wind is fierce down there this time of year. I am looking forward to warmer beach day for sure!
Beach outings we have a haversack with trowel, plastic bags, towel, water bottle and a bowl.
When on the beach we clean up poo, collect plastic (especially fishing line), dogs need to be wiped down after swimming to remove excess beach sand, drinking water for them when finished the walks.
Hope you get to the beach soon, all dogs love the run irrespective of the weather.
