    Lifespan of companion dogs seen in three independent primary care veterinary clinics in the United States

    Interesting research. Some of the findings (numbers in brackets are mean survival)
    - desexed dogs live longer than intact dogs, this is most noticeable in females. That's been shown in a number of research now
    - small but not signficant, difference between mixed breed (15.2) and purebred dogs from large gene pools (15.5). Although lower life expectancy in pure breds with higher levels of in-breeding. F1 Hybrids had highest longevity (16.1), but pool was smaller. Herding breeding mean was 15.2yrs.
    - Mean survival is 15.4years. Small dogs is 16.2 years and medium dogs 15.7 years
    - The Mountain ancestral breeds lived very short lives (not sure what these are, other than maybe a Bernese and St Bernard - maybe the big heavy dogs?)

    So the good news is, if a dog lives a full life then around 15yrs seems normal. I wish my Mr D had survived that long.

    Interesting. Only our first Sheltie made it to 6 weeks shy of 15. Youngest passing was 12, Asta had a stroke and did not survive it. I'm sure hoping for at least 15 with these 3 guys. :fl

    My only other Sheltie, Baron (avatar photo), just barely made it to 9. He died of something called hepatocytotropic lymphoma, a one in a million cancer that kills within a week or two of symptoms appearing. He got sick just before his ninth birthday, and because he had the best care possible and was diagnosed within 48 hours of symptoms appearing (by the luck of the draw a really really good veterinary pathologist ended up being assigned to look at his liver aspirate test and she happened to be one of the very few people who had ever seen actual samples of what this cancer looked like because of it's rarity and thus knew what it was without having to do a lot of time consuming research, so the diagnosis got back to the clinic in less then a day which was in time to intervene) he got emergency aspariginase treatment that temporarily saved his life. He still only lived eight weeks, but according to the cancer specialist that was more than double the amount of time that any other dog on record with this cancer had ever lived.

    My first Sheltie, Noel, lived to be 15.5. Other than going deaf and mostly blind, she was in decent health. I also think she had some dementia, now that I know more about it.

    Here is Noel at age 14, at the beach. IMG_1325.JPG

    My last dog was a Cocker that lived to be 15.5 and my moms last dog was a sweet Corgy cross that was almost 17! She wasn't doing too bad except in her last days her bladder was really really bad...we actually thought her kidneys were going because she couldn't stop peeing. Of course she'd lost so much muscle we had to carry her outside and back in and on ice she'd fall over. Sad to think back on it but that was the hardest day having her put down because she still looked like a happy dog, just with everything failing on her.
