It's a
collar that you put on a
dog so you can
control his/her
animal nature.
It can have
spikes on it, or cute little
pearls, or even a
name tag so when the little
bastard, or
bitch as it may be, gets
out of the yard, the
dog catcher can nail you for a
hundred quid fine, or just bring it back to
you, so you can
lock it up again.
It also can be
used on
people for
sadomasochistic fun and games.
Treat me like a dog is a line from a
Depeche Mode song,
Master and Servant, which is all about the pleasurable aspects of being a
dog. Put a
dog collar on, and experience your
animal nature.
