Having dogs share the load can save a lot of leg on a pack-in to upland camp. Ruffwear builds hard core active-dog gear. The Ruffwear Approach Dog Backpack ($60) has all the right adjustment points, fits close to the dog’s body and distributes loads evenly. It took a little time for Rio the setter to learn her new dimensions while carrying her food and first aid kit, but soon she was scurrying uphill without losing a step. When the Bivy Bowl ($23) is collapsed flat it takes up almost no space in the backpack yet when expanded it still has the rigid sidewalls to which my dogs are accustomed. This is a perfect combo for your camping bird dog and we even used the Approach with light loads to help build strength and endurance leading up to the hunting season.
Kapitan used this pack to carry my knives, game bags and 4 bottles of water when we hiked up to retrieve a bull elk. There are 2 types of chest add ons available as well, one for heavy protection and one for cooling
