We had to help my 12 year old Rottie, Max, to the Rainbow Bridge about 2 yrs ago. He was such an exceptional animal that we seriously would have had him cloned if it had been an option. It's terrible when they leave us, as they are truly family members (although some people really don't get this concept).
My Sammi is a true pleasure even when she's being a beast

Did you watch the video? The guy that put it together has some amazing imagination!
