The language of dog baby talk

I seem to have this strange effect on humans. I understand english perfectly well. Yet, when they are near me they start speaking this language of dog baby talk. Why do I have this effect on humans? OK, so I'm cute. Much cuter than the average dog. Still, it is kind of embarassing. My formal name is CoCo Bean. I say, "Hello, Madaam. My name is Mr. CoCo Bean." They take one look at me and began speaking dog baby talk fluently. "Aaah, what a sweet little pookie boy! CoCo Moco big boy!! Little precious puddin head!" Enough already, your kind of pissing me off.
