Pony back in the 70's had to be walked very, very carefully at a horse show. She adored tuna fish sandwiches and would pull the kids over to anyone eating tuna fish. She was fast and sneaky. After all who would pay attention when holding tuna fish. ponies...*shaking head*
When I took a lesson at my brother's barn the trainer was telling me about the big appy being used for the next lesson. Apparently they'll let the horses graze on the lawn in front of the stable row sometimes. He was out there one day when the day campers were at the picnic table eating lunch. He walked over, grabbed someone's tuna sandwich, and took off with it.
My horse is like this except with peoples' smart phones. If someone stands outside his stall with an iphone or other such thing, he sticks his head out to try to get at it. He likes mouthing the phone to get the screen to change.
When I was a kid we had an ASB who would come to our picnics (we had a picnic table in the apple orchard that the horses could get into) and eat our pb&j sandwiches and also drink Red Pop from a bottle!
Several years ago, when the farmer, from whom we bought our farm, and our handyman were doing some work in our pole barn, I had to bring my Shire mare and late Clyde gelding into the barn because I was waiting for the vet. We put up some hurdles (barriers) so that the boys could work without worrying about the horses. I got lunch prepared and set it on a work table within the work area. The farmer went to wash his hands and when he returned he couldn't find his tuna sandwich. Thunder, the Clyde, was licking his lips. I lifted his upper lip and found tuna stuck between his teeth! Who'd a' thunk it?!
A lady we boarded with had a cute thorobred that loved going to shows. Once retired from active showing he went to locals for kids to learn how to do in-hand classes.
Part of the reason he loved shows so much was for the hotdogs. Apparently he could walk by someone and nab the hotdog right out of the bun and keep walking. Became well known for it on the local circuit.
