How come dogs seem to be living longer now than they were when I was a kid? It seemed to be common knowledge that big breeds will live for 10 or so years and small dogs will live a few years more but now it seems that big dogs live just as long as small dogs (or maybe small dogs are living longer too)....Is it better food? Advancements in medicine? Better breeding? Or am I completely wrong? My Boxer lived to 10 years 8 months and apparently their average lifespan was supposed to be 8-9 years according to an older book (from the 80s)? They actually said you won't find many Boxers over 9 years.....now I know quite a few!
Well it's probably not better breeding heh. I would suspect better commercial dog foods and better medicine available to the dogs. But yeah dogs on average are living longer now than ever before. And the short lived breeds like great danes and such have longevity programs going so they can incresase the life span of those dogs to be more in line with human wishes.
In my opinion, its the opposite. I think dogs lived longer when I was a child compared to now. I belong to a board that consists of rottweiler owners. Last year there were at least 5 rottweilers that passed on who were under the age of 6. It included my female rottie who was 6, and a friend's rottie who was 2. The rottweiler owners discussed this "life span" topic a while back. Some one posted some good information about dogs in Europe and their life spans (not sure where she got the info). But she stated that dogs in Europe tend to have longer lifespans because they typicaly get raw foods and/or people foods (not junk) and Vets aren't as vaccination crazy as they are in the states. I only get vaccinations for my dogs that are required by law and that's a rabies shot. From another members personal experience, large breed dogs have a shorter life span.
on average, those and irish wolfhounds live only 6 to 7 years. Some females will live 9 or 10 years, theyr'e not sure why the males are so much shortlived. The problem with breeding dogs for longevity is that you dont know how long a dog is going to live until first, it's dead, and second, after it's past breeding age. So you have to look at the lineages and see who's lines tend to be the longest and go from there.
Smaller dogs can live much longer than a big dog like a Dane. The reasons are the size. The bigger the dog, the more work the heart would have to do, to send blood around the body. There are many other factors involved, but certain breeds age at a faster rate than others. Illness, poor diet, genetics, neglect, overbreeding(in females), a poor start as a pup and obesity, would all contribute to a shortened life span.
I bet it's just better medicene. It's just like in the human world right now. Sooner or later will be having more and more people living up to a hundred years old. It's true smaller the dog the longer they live. The only large breed dog that I know that have the same chances of living a long life as a small breed dog is the standard poodle.
i think too that it is better foods, better medicine, and also the humans (us) taking better care of our pets. we know they are like our kids and only want the best for them. i have seen pets die at an early age, but usually it is a genetic problem. sometimes you just never know, even if you get your pet from a respected breeder, there could always be something down the line to happen. for the most part, i think they are living longer, not only dogs but cats too.
