Hanne Quillevere, a Good Word subscriber living in Canada, was reminded by today’s Good Word, la-di-da,of a funny phrase now slipping out use. She wrote:
“If you are up to dealing with a phrase, rather than a single word, how would you trace the meaning of the phrase, “putting on the dog”? I have now looked through four reference works on idioms, slang and quotations, and while “dog” appears many times, “putting on the dog” does not. I have always thought it meant something along the lines of today’s la-di-da.”
The Oxford English Dictionary reports the phrase “put on dog”, e.g. in A. Gilbert’s No Dust in Attic (1962) xiv. 190: “Matron put on a lot of dog about the hospital’s responsibility”. Here the phrase uses “dog” as a mass (uncountable) noun. The phrase generally means “to splurge, to make a flashy display” or, as one of the OED citations puts it: “cut the swell”. I have always heard it as “putting on THE dog”, too, but I heard it only when living in the South.
This phrase means to do something up in a showy fashion, a synonym of that lovely British phrase, “(dress up like) the dog’s dinner”. (These phrases must have arisen during a stretch when all British dogs were show dogs.) It isn’t the same as “la-di-da” but both these phrases refer to situations that might well elicit a “la-di-da” or two.
