Possible to teach a dog to read?

Is it possible to teach a dog to read? I am going to try and teach Sassy. It may sound a little stupid and crazy but I really want to! Do you have any words I can use? I know easy ones. Like a familar word. Sit maybe?

I found this site which features dogs who can read

I suppose that it's just the same as dogs learning vocal commands, as long as you reward the dog when they've done it right then i suppose that they will eventually learn. I'm not to sure though, unfortunately i've never had the pleasure of owning a dog:(

Thanks for the site! Try to talk your parents into saving a life. Good luck!
