Outward Hound Quick-Release Dog Backpack - Jackets
One of the tasks my assistance dog sometimes performs for me is to carry things. After trying a number of other backpacks for my assistance dog, I settled on this one and am quite happy with it. It is sturdy, well made and has a larger capacity than some others I have tried, without being too bulky. It allows one to remove the backpack section and replace it without undoing the whole harness. This is presumably for backpackers who want to retrieve something from the pack, reorganize it or just to give the dog a break during rest stops but have the ease of getting back on the trail with less muss & fuss. I use the feature in similar fashion in more urban surroundings; when we're out for the day and there are times when he doesn't need to be actively carrying whatever we've loaded into the bag.
