My boyfriend just said something non-amusing to me and I told my dog to “sick 'em.”
Then I asked my boyfriend what the origin of the phrase was. I thought maybe it meant attack until you make so-and-so sick. Our best guess, then we decided to “dope” it.
When I was a lad, we had different dogs who knew the term well.
Say we were moving pigs from one place to another. If one proved uncooperative, a “Sic 'em!” would result in a torrent of all kinds of hell on the recalcitrant pig by the dog*. We would get them where we wanted.
A female collie, Candy, was the absolute best at adjusting porcine attitude. She could clear a five-foot fence with ease and sometimes herded the pigs just for her own enjoyment. Gotta love that.
*Actually, they were mostly “bitches”, but why inject technicalities?
We also had a female beagle who would “sing” upon request. “ArooOOOOO”.
What could be cooler?
Although “sic-em” is technically more correct, I really do enjoy thinking of it as “sick-em”, since I tend to warn victims that my dog has rabies just before giving the attack order…
