Cookie is a goldendoodle with lots of energy. He lives in downtown Minneapolis. Unlike people's common belief that dogs need a house with backyard, he enjoys this urban life quite a bit--he loves to stroll around downtown and say hi to people, or walk by ice cream shops to search for any spill on the ground. Cookie is passionate about living a high-rise multi-family lifestyle and advises D/O Architects on all canine related amenities.

Among his favorite things are brushing teeth with chicken flavored toothpaste, chasing squirrels in Loring Park, and taking a nap by the window while everyone works hard at D/O office. His goal in life is to be pet by as many people as possible and share his unconditional love.
