Eileen - 249708 Port Perry, ON 9/3/2013 4:03:12 AM My daughter has a soon to be 16 year old Lab and she continues to enjoy a wonderful dog. He is health and she respects his age. Yes he is slower, but he still has great quality of life. Along time ago her Vet said watch is weight and make sure he gets exercise regularly and it will make a big difference and it has. Thank your for this informative article.
