Some pups create bonds so strong that they become inseparable.

Pair bonded dogs are intensely attached to each other and can't imagine life without the other.

Often, pups develop a pair bond to a sibling or other pup that they've spent significant time with and grown up together with.

But pair bonds can develop without the pups having grown up together.

Such is the case for the two pit bulls Jukebox and Agatha who arrived separately to the Pima Animal Care Center in Tuscon, Arizona, but soon developed a very special bond to each other.
