I love Outward Hounds stuff.
I do too! I bought an Outward Hounds hip pack that had two water bottles with holders on the side, and pockets for treats and whatever else you'd want to carry inside. It also came with a nylon collapsible water bowl that fits inside a different pocket (to keep other belongings dry when you repack it). Then I got one of those little red fire hydrant things with a roll of baggies that it dipsenses out, and clipped it onto the hip pack. I love it for hikes!
