What are the chances that a coyote would take a dog home with it, play with it and then realise it's Jessica Simpson's pet and return it?

Pretty slim, say dog experts. It's more likely Simpson's Malti-Poo has gone to doggy haven. But don't tell Simpson that because she still has hopes that Daisy, her dog from ex-hubby Nick Lachey, will turn up barking and alive.

Earlier this week, the country singer Twittered to say “My heart is broken because a coyote took my precious Daisy right in front of our eyes. HORROR! We are searching. Hoping. Please help!”.

Just yesterday, Simpson Twittered again saying “Still holding out hope despite what some say is a dumb thing to do. Daisy is my baby … why would I stop searching? I'm a mum.”

Unfortunately for Simpson, celebrity dog trainer Jennifer McCarthy says that “if you see a coyote take a dog, one that is this small, chances of it surviving are very slim. Daisy's probably not alive anymore.”

Despite what many are saying is a lost cause, trained pet detectives from FindToto.com are offering Simpson their services for free. They are telling Simpson's neighbours to look in and around their property. "Check your backyard and under your deck. There is a chance the coyote would have abandoned Daisy and she's lying injured somewhere."

A spokesperson for FindToto.com told USMagazine.com, "We're kind of an amber alert for missing pets. We took the addresses of those living near the area where Daisy went missing and we used that as a bulls-eye. We called over 1,000 people and sent out a 30-second message with Daisy's details together with a number for Jessica's assistant so that anyone can give us information."
