Jess Lashes Out -- Why Would I Stop Searching?

Jessica Simpson still believes her beloved Malti-Poo Daisy isn't coyote food yet -- despite all of the "assholes" telling her to give up hope.

Simpson -- who watched Daisy get snatched up by a ferocious coyote Monday night -- just posted the following message on her Twitter page:

"Still holding out hope despite the assholes that say is it a dumb thing to do. Daisy is my baby...why would I stop searching? I'm a mom."
