Tender photos show the special bond between dogs and their owners

Dogs have been man's best friend since the dawn of recorded history. It's hypothesized that early hunters used dogs for their keen sense of smell. Australian Aborigines huddled with them to gain warmth on cold nights. Dogs have been buried with humans as far back as 1,000 BC.

Every dog is different and every owner is different, and the bond between the two is unique to them.

Photographers Ollie Grove and Will Robson-Scott set out to document these distinctive bonds in their recent project, "In Dogs We Trust." They traveled the world photographing owners with their pooches, and they found a trove of characters.

Grove and Robson-Scott shared some images with us. You can see more and buy the book at their website.
