Have you seen and heard the dogs that communicate by using prerecorded word buttons?
They have keyboards of pushbuttons laid out on the floor. Step on them in a series to build sentences. Dog can do the same.
Presto... Dogs can now communicate with canned speech.
No I have not.
However, I have Beagles and Chihuahuas.
They’re not that smart.
Maybe something a Border Collie or a Doberman could do.
