She's adorable... so small and so cute!!!
Whose hand was that? It it's yours it's a bit worrying that your own dog would growl at you. I know Chihuahuas are small and cute, but they're still dogs.... imagine that was a Rottweiler or a Dogo Argentino doing to you?
I've had all kinds of breeds and never heard a sould from them if I took their food away.... including my Chi.
It's a big NO NO!
