Guide dogs are highly trained at acting as the eyes for their blind owners, but sometimes they can be quite skilled in matters of the heart as well.
In 2012, Claire Johnson and Mark Gaffey were strangers who had both signed up to be paired with seeing-eye companions at a guide dog training program in the UK. During the rigorous two-week course, their new Labrador retrievers, Venice and Rodd, became inseparable -- and soon enough the two humans did as well.
"As the weeks were going on, everyone was saying how much our two dogs seemed to be getting more friendly with one another than any of the other dogs," says Mark.
"In fact, the trainers said that it was the romance of the course, the two dog," adds Claire. "They'd always pull towards one another, ignore all the other dogs."
