I assembled a system to transport my 65 pound dog, Sasha. This system provides solutions to all the important aspects involved in taking her to the park where I play sports, all in a minimalist, multi-use package.
(1) dog transportation to the park by bike.
(2) Easily anchoring a long leash into the ground so dog won't run away while playing sports
(3) Shade for dog
(4) Entertainment for everyone that sees dog in backpack
