Well not QUITE, he responds to my dragon shouts.I've successfully trained my dog to respond to the most common dragon shout, "Fus-Roh-Dah!"
i've been training him for weeks but (funnily enough) on 11/11 he finally got the hang of it. I should post a youtube video of it.

When i say "Fus!" He barks once
When i say "Fus-Roh!" he barks twice (though i have to follow up each word faster than it is said in skyrim, so he understands)
When i say "Fus-Roh-Dah!" he barks three times.

Its so cool to walk down the street and go "Fus-roh-dah!" and he follows with barking.

Any ideas on what i should do next? Whirlwind sprint! =D

Gah, second page pretty quickly.

and then fight him with a broom! EPIC DRAGON FIGHT!

You gotta theach him how to fly, also.

teach your dog to say it not bark it

So you actually did not teach it to dragon shout.
