I love dogs unleashed and in packs and being the leader, it's magic.
Can't wait until I have a pack in my backyard and take them places like that where we can be free.
It is interesting how they relate & "pack" as you say..
The last pix is Josy with one of her sticks, WE do stick with the dogs most of time.. they like it on land, into streams, in lakes.
Josy -shown in last pix with stick- as a german shepherd does NOT have sheep etc to herd so she herds either sticks or rocks (and large ones), She will steal the others sticks & keeps them in pile & protects it with a passion
