Hey, I'm not the only one who doesn't do "pack walks"! When I've got a good group I'll put everyone of approximately the same size/power on one hand and let them braid. No way I can do that with the current pack, and if I let a stronger dog get tangled up in there they end up dragging all the littles.
Ru walked in tandem with our foster chihuahua that was just his size. The two of them made a perfect brace and could have walked on a coupler. Ru is oblivious to any other dogs walking with us though, and way too tiny to couple to a real dog.
Briz will walk nicely with dogs that have good leash manners. When I walk the two of them together it's one leash in each hand. I also occasionally do two flexis with them because Brisbane has flexi manners and Ru is of no consequence.
Ulysses doesn't exactly pull on the leash, but also moves in a very random and erratic fashion and doesn't quite get that he's walking with a group. Sometimes he's not even coordinated enough to get all of his own legs moving in sync.
Right now I don't usually take all three out. When I do, I usually have Brisbane on an over at her shoulder leash and Ru and Uly on separate hands. It's like herding cats, and drives Brisbane nuts.
