Pup Science Khaki RANGER - Premium Human Grade Dog Backpack for Medium, Large & XL Dogs Keep poop separate from your food and water - With 4 compartments you won't have to put your dog's moist, steaming, poop (blech!) next to their food, water or your cell phone and car keys. Fits even weird shaped dogs - Our 3 point locking system molds the backpack to your pups shape for a custom fit. As long as their girth is 30-38 inches, they will fit! Pull the zipper with one hand  Youre holding your phone in one hand and your leash in the other, juggling a bag of fresh dog poop and now you cant even find or grab the zipper?? We hate that too! Thats why we made large zipper pulls that you can pull with one hand or with gloves on. No more dangerous extra straps  You spoke and we listened. Unlike other companies, our adjustable pack straps now have all the dangly extra long bits all tucked away. No more straps that could wrap around your dogs legs and crash them to the ground, no more straps that could get caught and choke your dog between the ribs. They wont change their production lines to save your dog, but we will! Complements your people gear  Do you ever wonder why they make dog stuff so ugly? All those bright reds and greens that your dog cant even see because theyre color blind. Weve finally made a dog backpack with a traditional vintage look that fits in at the dog park, in the city or in the woods.
