Nope, just have to deal with this enough with other people to realize, what he maybe talking about.
Ahh yes, because of course Patio doesn't deal with other people to realize. After all, to my understanding he only owns/works in a repair shop. you never see people there, they send their dogs in with the computers and you have to interpret the barks. He even has a name tag that says "Dog whisperer".
EDIT: useless trivia: did you know that the dog language has over 200 different conjugations for "bone"?
