Mighty disappeared from the 43-year-old’s home in Montecito, California recently and the dad-to-be is asking fans in the area to be on the look-out, posting a string of snaps of the lost dog on the photo-sharing site on Wednesday.
“MIGHTY IS MISSING in Montecito California he is chipped and his collar has a number to call – if you take him to your local vet or shelter or police station he can be traced back to me for a reward (sic),” the actor wrote.
Calling on the kindness of locals, he added: “please only send REAL INFO my heart is already broken so please don’t add insult to injury (sic).”
The drama could not have come at a worse time for Bloom, who expects his second child with fiancee Katy Perry to arrive imminently.
Kate Hudson was to give her prayers amongst the friends of Orlando.
“Dear Mighty (praying emoji hand) love you guys,” she wrote with a heart of gold.
Kate Beckinsale liked the message, and also commented on Helena Christensen.
