Jessica Simpson has called in pet detectives to help find her missing dog Daisy.

The animal was stolen from Simpson's Los Angeles home earlier this week by a wild coyote.

According to Us magazine, trained animal detectives had called 1,000 neighbours in the surrounding area and sent out a 30-second message with details about the dog.

In a message on Twitter on Tuesday, the singer said: "My heart is broken because a coyote took my precious Daisy right in front of our eyes - HORROR - we are searching, hoping, please help!"

Simpson posted an update yesterday, in which she hit back at people who had criticised her for using the social networking website to help find the dog.

"Still holding out hope despite the a**holes that say it is a dumb thing to do - Daisy is my baby... why would I stop searching - I'm a mom," she wrote.
