Trying to get E to say "Dog"

So Elliot said dog twice and now mostly just calls the dogs, "dad, dud, or duhd."
Here you can see (with my coaxing) that he says it--but not nearly as clear as he has. It's funny when real words come out of your "baby's" mouth. It makes you realize how fast they're growing.
P.S. Does it shock anyone that his first real word (ie: connected with the correct object) is, DOG? Maybe he'll grow up and run a dog rescue and then his mama can save all the dogs in the world...
or maybe his next words will be, "mommy is thinking about my first word too hard"
