I was told they are, by Chad, who partnered with Ringo, his Belgian Malanois, in Kuwait (on my profile page).
In the picture are both. Chad & Ringo are far left. They have since retired Ringo, who came down with something. It's been too long...can't recall. Ringo was about 10-12 at the time the photo was taken.
Could Chad's family have had first option in adopting Ringo on his retirement?
