Throw Back Thursday #18 : Dogs, Animal Control, Salt Lake City History, 1961

 Here are parts of an old brochure on being a good dog neighbor.  It was published for Salt Lake City Animal Control as a public service by the Ralston Purina Co.  It does have a copyright on the brochure for 1961  and I would guess it's accurate based on this online comparison: https://www.ncbi.nlm.nih.gov/nlmcatalog/101633401.  It fits the criteria and is 9 pages in length in its entirety.
