Ugh ... it depends on who you ask and where they got there dog?? 6 months to 3 years, in a case scenario, is not uncommon here.
Usually that would be Cancer or Heart Issues. And then after your well past that milestone, there is Degenerative myelopathy and that usually strikes in year 8 with early sighs before then ...clicking sounds fro a dragging right rear foot on hard surfaces.
The best protection against these issues is a health tested puppy form a quality breeder. More dollars up front but less "heartbreak" in the long run. Aside from those "issues" 10 years can be expected. But we do have dogs at 12 years or more on here! And I think the longest lived Boxer was at least 18 years or more!!
But that ..i s most differently not the norm!! A long lived life ...is saddly, not one of there things. My Struddell barely made it to the 10 year mark and it was DM that took her down.
Well con!graduations, and Happy B-Day, to your girl You deserve extra credit for taking on senior dog's! It takes a pretty special person to be willing do that!Layla is presently 11 (June 30th, HappyB gurl!) and has a few scary bumps on her but vet says they wont do anything to her since she is old and dont seem to be in any type of discomfort; in fact, apparently her heart will probably give up well before any type of cancer can sweep her away (normal old age dog cause of death, the preferable one_) I indeed notice that she cant do the long circuit we used to do every day anymore, maybe 3/4 and not every day.
16? I love it. My first boxer lived until 11, then my second, who was the runt, lived to 12 with cancer and my third will be 7 in April. He ate a pacifer when he was a baby and had surgery. I watch what I feed him. He is on a raw meat diet with veggies and fish. I sometimes put mint leaves in his food for his breath. So far, all is good. He also takes a long walk every day. Vinny and Roxy16 is pretty freaking amazing! So far regardless of Breed my dogs don't make it past 10.
