RottweilerA research veterinarian kicks off a 23-day trek crossing the nation this week to visit the oldest living pet Rottweilers in the United States. His mission is to learn the biology behind aging.

While most scientists dedicated to discovering the biology behind why we age study worms, flies and mice in cages, David Waters will add aging canines to the list. “The Old Grey Muzzle Tour” begins in Harrisburg, Pa., on Thursday, March 11 and will end April 3 in Seattle.

Waters is executive director of the Gerald P. Murphy Cancer Foundation, based at the Purdue Research Park of West Lafayette, Ind. The Murphy Foundation is home to the Center for Exceptional Longevity Studies, where Waters leads a research team that studies aging and cancer in pet dogs.

Research includes the study of exceptionally long-lived Rottweilers – individuals who have lived to at least 13 years, which is equivalent to a human living to 100, according to Purdue University researchers. At each stop, Waters will perform a physical examination, collect DNA samples and record measurements such as height and chest and belly circumference.

He will also observe each dog in his or her home environment and query owners on what makes their dogs exceptional. Along with collecting scientific data, the goal of “The Old Grey Muzzle Tour” is to raise visibility for this kind of scientific work.

The itinerary of the tour also includes: March 12, Holliston, Mass.; March 13, Philadelphia; March 15, Keysville, Va.; March 16, Columbia, Tenn.; March 19, Cambridge, Wis.; March 20, Riverside, Iowa; March 21, Alma, Kan.; March 23, Red Oak, Texas; March 24, Castle Rock, Colo.; March 27, Colorado Springs, Colo.; March 28, Tijeras, N.M.; March 29, Waddell, Ariz.; March 30, San Diego; April 1, Pacific Palisades, Calif.

Update on my comment in 2010. Today is Dec. 27, 2011 - Harry, our OESheepdog, was diagnosed with bone cancer in his front paw and passed on Thansgiving, 2010. (he was 11/1/2). Dory is now 15 , soon to be 15 1/2 next month and her baby, Paddles is now 11. Dory is deaf but reads signals (glad we taught her when she was a pup) and has a skin infection we have been treating since August - we have been told by several Vets that it is her immune system wearing down and the skin infection is a bacteria. With several blood tests, she has an underactive thyroid which is being treated now. Both Potugese Water dogs still play and romp like they are puppies and enjoy their
Would love to hear from anyone with aging PWD's!

Today my dear mother had to put her sweet Old English Sheep dog to sleep. She is a wonderful, loving owner who had kept a family pug alive to age 19. Rollo the Sheep Dog was 13 years and 7 months old at his passing. He was very much loved and will be sorely missed. I do not know a better friend to animals than my loving mother and I

My Samson, a warlock Doberman, was born march 10, 2000. He is very energetic and healthy. Everyone that meets him thinks he's 2 or 3, and shocked to learn that he's 10 soon to be 11. Samson is my heart and soul and friends call him "the gentle giant". He has out lasted my wife and two girl friends. He is a warlock and stands 31" tall and 92 pounds. These are great dogs and would recomend them to anyone that has time to spend and train them. Great companion!!

Sampson, our bloodhound, is approaching 12 years old. I am trying to find out if this will be a record in age for a male bloodhound!
