Teach your Dog to Say I Love You

Have you ever seen those videos of dogs who are able to bark out phrases like "Rye Ruv Roo" in that characteristic Scooby Doo voice? Have you ever wondered how those people taught their dog a trick like that?
I was wondering the same thing, and decided—partly by accident—to see if I could get my dog Mukha to learn a few words!
When the Sirens Wail, so do the Dogs
Mukha, like many dogs, has the instinctual tendency to howl at ambulance or police sirens as they drive by, and I've never been one to get annoyed by this. In fact, I quite like to watch her yell out to what must, in her mind, be some lonely dog in the distance. On more than a few occasions, I've even howled along with her, which really prolongs the whole experience—much to my neighbor's delight!
After several of these performances, I noticed that she would often mimic the pitch of my voice. If I let out a low, quiet howl, then she would follow suit with a half-hearted baritone moan! She even started to copy my mouth movements, which is when I really thought it might be possible to squeeze a word or two out of those melodies!
