If you Google, you can find stories of border collies that learned the names of hundreds of individual objects, so that their owner would be able to tell them, “Bring the small red ball” and they would happily do so.
Don’t any of you people have kids?!?!
Our dog, too, will jump to his feet, er, paws if he hears the word “walk.” So we refer to a “going on a W” instead; he still, after nine years, hasn’t figured out the substitution.
When my son was little, we used to say to one another that we might go to “the Scottish establishment” for lunch or dinner when we were discussing plans and didn’t want him to hear that we were considering getting McDonald’s.
Heh. I make that joking reference to McDonald’s myself, now and then, but not to hide what I mean from anybody. ISTR that H.G. Wells in Time After Time enters a Mickey D’s in San Francisco, thinking it might offer Scottish cuisine.
Well, sure, but they’re in their forties and have caught on to all the tricks–even the youngest grandchild is ten and likewise pretty savvy. 
My first dog overreacted whenever he heard “walk”… or “stroll”… or “hike”, or “trek”, or “perambulate”, or “constitutional”, or any of the other words we could come up with. We eventually resorted to just leaving a blank spot in sentences wherever that word would go.
Some of my cousins always reacted to “ice cream”, and so my aunt and uncle started spelling it. But the kids learned that whenever their parents were spelling something, it meant ice cream, and so they would nag them and ask for RQZ HDOAL or whatever.
When visiting relatives, their young child had learned that beer and wine were bad. So they called them daddy juice and mommy juice instead.
The little Bobs are the worst!
I know a software guy whose dog is similar. His abbrev. naturally is SQL.
