There's also no central certification body or standardized certification requirements as to what makes a "service dog."
Several of ours have AKC Advanced Canine Good Citizen certification, but that just means they have passed tests showing they behave properly in public. FWIW, we've paid the $75, then $100, now $150 or whatever it is one-way every time we've traveled with a cabin pet.
