Earlier this month, 8-year-old Lexie Taylor had her chihuahua-cross puppy, Caramel, stolen from her home in Harlow, Essex, during a burglary.
Ten days ago, the family launched a campaign on social media called "Find Caramel", which has gained over 14,000 fans.
Lexie's mother, Tracy Taylor, told the Harlow Star that her daughter "cannot understand what happened, and she was crying in bed all of last night. They were inseparable."
As Essex police search for Caramel, messages of support have flooded in for the Taylor family from around the world, although they have so far received no leads on her whereabouts.
Lexie and her family are devastated, and are offering a £1,000 reward for Caramel's safe return.
"We don't want to win the lottery .... Just want Caramel home x", they wrote.
BuzzFeed News has reached out to the Taylor family about the overwhelming response they've received to their Find Caramel campaign.
On Monday evening Caramel was returned home safely.
