As a Labrador swam by me out to sea his owner said I hope he doesn't meet a seal

Herding skills, sheepdogs https://www.youtube.com/watch?v=lAjc502ALOM

Also reminded - we had neighbors with 2 cats, an experienced and cynical large red one and a naive curious tabby. They spent a lot of time outdoor wandering around, and the tabby was always trying to get everywhere, very friendly, and the red one was always very suspicious about everything and very worried and watchful over the tabby. Unfortunately the tabby got killed by a car. The neighbors after some time took another cat. The red one never let the new cat to leave their patio. Getting to sit on the patio fence was the maximum she would let him, and on any attempt to get down outside of the fence she would firmly herd him back.
