Hitch up your knickers on Work Like a Dog Day on the 05th of August 2019. The common English idiom to work like a dog refers to working really hard. Like sled dogs or sheep dogs for example who extend themselves and always keep going. Although the initiator of Work Like a Dog Day is unknown, just like his motivation, this gives us a clue on how to spend that day best: go and work yourself into the ground like a dog would do. After that you might as well nap like a dog, pleased and anywhere you want. Work Like a Dog Day is one of many more fun holidays in the USA about dogs, like Walking the Dog Day or Take your Dog to Work Day.
