A hunan skull (sic) in hubei might otherwise be unsurprising.

Naturally, hearing colours, seeing sounds and tasting shapes is the sort of conceptual synesthesia I'd be likely to indulge in if I was looking for and finding my voice here or there.

It looks to me like the dog is only being trained to hit the buzzers in hopes that eventually they will get a treat.

When my dog is walking down the street
I see red, I see red, I see red
Every hydrant stop is deep pea green
He sees red, he sees red, he sees red
I see red, he sees red
I see red

Funny. But if this is part of a training game, the the buttons seem to be badly designed, since dogs are red collour blind, so they would not be able to tell all the buttons apart.
