Livestock guard dogs go from play to work in seconds

While these Maremma/Great Pyrenees dogs tumble and play in the snow, one of them hears something at the other end of the field. In an instant all 3 dogs spring into action, ready to go to work. This is excellent livestock guard dog behavior; Fingal and King are out on point while Maple hangs back to protect the livestock (in this case it's their owner who is filming). We're not sure what it was they went after, but they sure know how to flip the switch!
