doggy bag (or doggie bag) is a euphemism for the container in which a restaurant customer carries home any food that he or she was served but had not the appetite to finish. Rarely is it intended for the dog but rather may be the basis of the next meal at the domestic table. Early references are from the states of Washington and California in America during the 1940s. They certainly presume the dog as beneficiary. The Pet Pakit was a model of bag in San Francisco in 1943, and another pre-printed container in Washington had the rhyme,
Are you happy over dinner?
Don’t have all the fun alone.
Remember the pup who’s waiting
And take him a luscious bone.
