I have setters, they are like a Def Leppard song, some burn out before they fade away. Ive had several that were dead by 8 and half a dozen make it to 14 plus, those dogs were still hard chargers when I put em up as retired at 12/13, deafness and sight is what made them training day dogs. The sickest feeling you'll ever feel is losing one miles from the truck and not being able to find them. I got a telemetry system shortly after that event. Was long before a garmin was ever thought about. If there's a health type issue it's most likely time to get a youngster started .
