Dog Repellent

November 18, 1964, Neenah-Menasha Daily Northwestern

This item is a bit out of kilter with the summer themes lately, but I was taken with the concept of the postman out on an average hot summer day and what more aggravation does he need than a pesky dog who won't leave him alone.  Not sure when the concept of pepper spray was put into practice (World War I brought chemical warfare to the forefront, but that was a lot more serious than this), but the article writer here makes it sound as if we've never heard of it before.
