I think labs and goldens average around 11 as a general rule. However, it depends on lots of factors. Our first golden, Copper, wasn't a bird dog, and he made it to 11 before his hips went out. In comparison, Calvin hunted extremely hard (20-30 full days per season) for 9 seasons without any significant injuries before developing chronic arthritis in his front legs followed by hip problems the last couple years.Hrmm a curious thought just hit my mind. What kinda life-span do you get from your guys "bird-dogs"?
Thought I had because my Rat Terrier made it 15yr. but I seem to recall that like for labs and stuff, it's more like 12-13yr right?
And man.. after my first baby passed.. I learned that Great Danes are only like 7-9yrs!? OMG that's just barely enough time for them to become an integral part of your life just before getting ripped back outta your heart again!
One thing I learned when buying my griff a couple years ago is that some vets are recommending not neutering male dogs until 2 years of age. Some studies have shown that waiting until dogs are fully sexually mature and can prevent musculoskeletal issues later in life like the arthritis our goldens both experienced. They were both neutered at 6 months or whatever the recommendation was back then. Oscar gets cut next month and he will be 2 years and a couple months. There are some griffs on the facebook groups that are 15-17 years old and still getting around very well. I'm hoping I get lucky with Oscar, because seeing them languish and deteriorate is too hard to happen every 10 years or so.
My brother has an english mastiff that weighs around 160 pounds. Large breeds like these and danes average around 8 years from what he's said.
