Blossom (just recently turned 1) is a German shepherd mixed with something that has even more hilariously ginormous ears than a German shepherd does. Which is saying something. Perhaps a German shepherd/donkey mix?
Fully collapsable, too. Here they are folded back for maximum aerodynamics…
…and here they are fully deployed, for maximum hear-a-treat-fall-on-the-carpet-at-400-feet capability.
