This masterpiece of doggerel (sorry, I couldn’t help myself….) is a promotional brochure for the products of the Miller Dog Food Company of Battle Creek, Michigan. The company started out as the Battle Creek Dog Food Company, and I am not yet sure when it changed its name, but the typography and design suggest the 1920s to me. Located in the same community where Kellogg’s cereals were produced and where Dr Kellogg had his famous sanitarium, the early ads I have found for Miller’s Dog Food promoted it as health food for dogs. I’m having trouble imagining this as a pet shop giveaway, given its barroom tone. But I leave you to peruse it. In fact, I suggest reciting it out loud!

This poem was first heard by your correspondent in or about 1946 when it was recited by Mr. Joe Hildebrand, then a Distric Commissioner in the Baltimore Area Council of the Boy Scouts of America. Mr. Hildebrand was to often recite this poem to the great amusement of parents of Boy Scouts on the occasions of Mr. Hildebrand visitations to gatherings of parents of boys in the Scout Troups within his District.
