Are dogs ONLY man's best friend?

This arrived on my email today. I’d love to know who these belong to.

Suryia and Roscoe - Best Of Friends

Where you lead, I will follow...best friends Suryia the orangutan and Roscoe the Blue Tick hound.

Doggy paddle's the order of the day here for the couple who live at the Tigers sanctuary in Myrtle Beach, South Carolina.

Suryia and Roscoe spend hours together every day - they're particularly keen on swimming.

The two mates see the funny side of most things.

There's always time to chill.

For once, Roscoe's letting it all hang out.

The three-year-old orangutan goes everywhere with Roscoe.

A dog's not just a man's best friend, he's an orang-utan’s too.
