What Is Old for a Boxer?
“Old” is a relative term. Obviously, if you have a boxer that is over ten, you will be the envy of many. Ten for a healthy boxer is about sixty-one in human terms, an age in human terms that covers a wide variety of conditions and situations. Some people run marathons at this age, and some are completely bedridden.
Even with the Hollywood attitude that fifty is the new thirty, sixty-one still encompasses a lot of variations. Some boxers go over their full AKC jump height at age twelve and older, while some cannot jump after the age of six. A lot of this has to do with the line that your boxer came from, and a lot has to do with the fitness level that you have helped him maintain throughout his life.
If he has had sensible, regular physical exercise, as well as regular mental stimulation through life-long training and high-quality food, the chances are that he will be doing very well. Many upper-level obedience dogs (dogs showing for their UDX and OTCH titles) are still in active competition from the ages of six to ten (which has often been called the “Golden Age of Obedience”). Some boxers have had honorable mention in Front and Finish, the obedience competition magazine, at advanced ages as old as eleven, and some boxers have finished their Novice A agility titles at eight. Aging often really depends upon the physical and mental stimulation your boxer gets, in combination with good genes and good food.
Holistic practices look at aging in dogs a little differently than the old “seven years to each human year” rule that used to be the standard in determining a dog's age in human years. Some holistic practitioners feel that the first year of a puppy's life is like fourteen human ones; the second year is like seven in human terms; and each year after that is about five years in human terms.
