I always thought parrots would be more useful to the blind than a seeing eye dog. After all, a parrot can tell you what is around you. All a dog can do is tug at your hand.
..it scares their dogs..
Yeah, like a service parrot is gonna cry out "Caution! You are approaching an intersection!"
Parrots can articulate words, but they haven't the faintest understanding of their meaning.

P.S. My service chameleon just ate my cricket companion.
