I purchased a backpack for my gsd but have not used it with any weight in it . My Vet said I shouldnt put weight in it until he is at least 18 months, as being a large breed dog they are still growing and don't want to put strain on his joints. We do put poop bags some cash (just in case the ice cream truck passes) and his folding water dish. On hot days a frozen water bottle on either side would be awesome! But if its to hot i wouldn't even use it!

When I put it on him he is so proud!It is almost like he is showing off!!!
