Just remembered Heidi, Pru, Chico, and Rita.
I saw Heidi push a level water bottle with a bowl at its end into a hole with her head so that the water flowed into the bowl. Smart German Shepherd.
Chico and Rita team up in their big yard to come at prey from different sides like some kind of 21st century velociraptors. They have caught and killed a number of squirrels, mice, kittens
, and other critters.
