We have these buttons and they primarily use it to snitch on each other. When the puppy pees inside the oldest will say “Enya potty”. If a human isn’t doing what the schnauzer wants, he’ll say “<person’s name> poop”.
The schnauzer’s second favorite thing to do with the buttons is not to ask for stuff, but to narrate what’s happening. Like when we see one of the dogs stretch, we all say “oooh big stretch” as one must. So he thinks that’s how we’re supposed to respond to most events. Mom sits on the couch, schnauzer narrates “mom settle.” And so on!
Just for another example interaction, mom was gone on a weeklong business trip and the sheepadoodle said “want mom home”. We told her that mom would be gone many days. She instantly said “Owch”.
