not long enough...
Tossie was almost 13 when she left us but there are boxers on here that are older than that I believe. Sophie is one I am thinking of, if she isn't that old she is close. I believe it has to do with bloodlines and how they are taken care of such as good food and such. I also believe vaccinations have a large deal to do with it too, but that would be with any dog, not just boxers.
