JESSICA SIMPSON is desperately searching for her beloved dog after the pooch was snatched by a wild coyote.

The singer has launched an appeal for fans to help her try and track down her pet dog, Daisy, through her Twitter.com blog.

She claims the mutt was grabbed by a coyote while she looked on helplessly - and hasn't been seen since.

On her Twitter.com blog she writes, "My heart is broken because a coyote took my precious Daisy right in front of our eyes.

"HORROR! We are searching. Hoping. Please help!"

The family is calling for any information and has provided an email address for anybody who believes they may have spotted the pet.
