Larger animals tend to live longer than smaller ones… most of the time. Think about it. A human lives longer than a cat, which lives longer than a rat, which lives longer than a fly. But why isn’t this true when it comes to animals within their species?
A person who weighs 150 pounds will most likely live longer than a person who weighs 300 pounds. This is because of increased health risks for the person who weighs 300 pounds.
When it comes to the life expectancy of dogs though, how can you compare a Great Dane to a Chihuahua? Their anatomic builds are completely different and their lifespans reflect this. But, beyond size, is there an average age of a dog based on breed or other factors? Yes. Let us explore this subject further.

Dog Care
As the owner, you can affect the care you provide for your dog. A dog with a proper, nutritious diet and exercise can live longer than one without. In addition, taking your furry friend to annual wellness exams at the veterinarian and getting its booster shots can result in a healthy dog with a longer lifespan.
Dog Size
Research shows that larger dogs live for a shorter period of time when compared to smaller ones. For example, an Irish Wolfhound (average 115 lbs) has an average lifespan of 7 years, while a Jack Russell Terrier (average 15 lbs) can live up to 13-16 years.
Inbreeding vs Cross Breeding
Inbreeding can reduce the lifespan of canines. Cross breed dogs have a longer lifespan in comparison. Inbred dogs have a risk of carrying genes for illnesses that are common to that specific breed. Further, “mutts” who have at least two breeds and commonly more, tend to have the least health problems and live longer than their purebred counterparts.
Spayed/Neutered
Spaying and neutering a puppy at a young age can positively affect a dog’s lifespan. Studies suggest that these surgeries can help reduce the risk of some types of cancer in dogs. Especially cancers affecting the ovaries, breast and testicles. Recent studies show that these benefits may or may not completely accurate but there is no question that your life will be easier without a litter of puppies in your life and this will also be less stress on your pup, which could mean a longer life.

10 Dogs With Short Life Expectancies
You’ll notice that most dogs in this chart are larger breeds. As mentioned above, larger dogs tend to have shorter lifespans than smaller ones. Some believe this is because large breeds age quicker. For example, a Great Dane can gain 100 pounds from its day of birth to its first birthday, whereas a Shih Tzu can weight up to 15 pounds in its entire lifespan. Below is a table of ten dogs with short lifespans.
Dog Breed | Average Lifespan |
|---|---|
French Mastiff | 5-8 Years |
Great Dane | 6-8 Years |
Bernese Mountain Dog | 6-8 Years |
Irish Wolfhound | 6-10 Years |
Neapolitan Mastiff | 7-9 Years |
Leonberger | 8-9 Years |
Newfoundland | 8-10 Years |
Saint Bernard | 8-10 Years |
Scottish Deerhound | 8-10 Years |
Bloodhound | 9-11 Years |

My boy Jack is 3/4 Labrador and 1/4 Flat Coated Retriever. He turned 3 last month. He’s my best friend, I never want to see him take his last breath but everything happens for a reason. Just gotta make sure he continues to have the best possible way, with me by his side the whole time.❤️
We have a 15 year old Chow/shepherd mix. His back legs (hips) give him some trouble so he is on an non-steroid anti inflammatory meds no but he seems happy and is active (between his long naps).
My chihuahua just turned five this year. Her birthday is February first. She loves everyone. My pittbull is 8 her birthday is Halloween she will be nine this year.
We have a 16 year old Rat Terrior, Mr. Bean. He is my husband’s therapy dog, and still enjoys car rides and daily short walks. Still has most of his teeth, but his appetite has slowed to one meal daily. We also have a 13 year old Chiuaua, MooMoo. He still has good energy, and is always hungry.
Rufus and Tinky were born in December of 2004. They are, what one might call twin Pomeranian runts born numbers 4 and 5 of the litter of 5. My husband died in December of 2014 and ever since then, these two babies of ours have been waiting for my husband to walk through the door. As the years go by they have lost almost all their teeth. I hand feed them every day. They spend the day sitting by the kitchen door waiting for the one that will never be back. People aren’t the only ones who hurt.
I lost my pitbull/american bulldog/mastiff mix, Bruno, at 7:45 Am on September 27th, 2019 from lung cancer. My family rescued him as a 5 week old puppy who was taken from his mom and siblings way too early (he sucked on his blanket and my blankets up until the day he passed) and he quickly became my dog, my companion and my best friend. He was the best boy, always knew what time i was coming home everyday, always gentle with the farm animals (including the little baby chicks!), wonderful with my neighbors cats and the best hunter (he rescued our farm animals by scaring off foxes and coyotes when him and i did perimeter checks!). Every night he would sleep in my bed and right up until the last month and a half, he would hike 3 miles with me everyday. I started giving him massage therapy and we did our range of motion exercises before hiking, but as he started getting older, he could no longer get on my bed and started using his orthopedic dog bed i bought him. Soon he started struggling to breathe, couldnt make our walks and i took him in to do chest xrays to figure out what was wrong. The vet called me and told me he stopped breathing on the table during the xrays and they were able to resuscitate him but with bad news. He had 2 weeks to live and was diagnosed with lung cancer (i was informed that chemo and radiation would not fix it). He made it three weeks and EVERY SINGLE NIGHT until the day i brought him in to be put to sleep, he slept in my bed and we spent as much time together as possible. I loved him so much, he was my life, and the center of my universe. He was so well behaved he was allowed to go into some of my college classes, into stores that didnt generally allow dogs and an apartment complex with strict rules (he never really barked!). I miss you so much old man, i have done so much research when he was alive on how to “make dogs live longer lives” 🙁 i wish i could have spent 80 years with my boy. Bruno, you were the best dog and I wish more than anything that i could bring you back to life
This broke my heart.

She runs all over the house at high speed, chasing the cats or just by herself every night for 5 to 10 minutes. She is turning pretty gray and is almost blind and deaf. She only has her front teeth left. We love her so much. Her aunt passed at 24years 5months old. Her name was Buttercup.
My dogs name is Teak he belonged to a builder hence the name you know like the wood. Any way I think he (the dog) is about 18. He has been fixed. Big N in his place. Sorry he never had sex. well what I’m getting at is how long can he go?I think he is a mix golden he cant see too well and dose not hear to well ether. Im buying cooked chickens and pull the meat off the bones. He seems too likes it. He didnt like Blue buffalo even when I mixed cooked chicken liver. I think he got tired of it! Now he sleep a lot and has a hard time getting up. His rear legs dose not seem to have the strength. Love the guy, been the only being that came to me, good or bad. If he goes before me I would like to have him cremated. Im in western NC. dont know were to go for that. Hes the best friend I every had.

We have a Labrador/ Shiba dog mix that we adopted as a 9 week old puppy from G.A.I.N (the shelter in Guam) 13 years ago this November. Our boy has started slowing down over the past year or so, but still loves his daily walks and eats just fine. But his pace has slowed and getting up has become hard. Not ready for the day he crosses the “Rainbow Bridge”.
I have had my Great Dane for 7 1/2 years now and I think her time is slowing starting to dwindle as she doesn’t want to get up and go outside as much or eat or basically do anything. Shes the first dog I’ve ever owned, this is going to be tough on my granddaughter and myself.
I am a boxer owner, or rather I am owned by boxers. My first lived 10 yrs 5 months. My second 12 yrs 5 months. (He lived 20 months past what I was told to expect after they found an inoperable mass on his spleen.) I have one now that is 12 yrs 7 mos. I was hoping she would make 13, but she was recently diagnosed with a brain tumor, so I don’t think that will happen. I also have a 6 yr old, and if the pattern holds true, he will make 13. With each one I learn more about nutrition and supplements.

My Chihauzer (chihuahua schnauzer) I pronounce it Chi-wow-zer :), is going to be 13 this summer and is my forever puppy. She’s still full of life and energy. She has adapted well to my human child over the last 2 years of his life (she actually knew I was going into labor before I did). She did seem a bit depressed when my son first came into the world, but now she loves him and is playful and protective. I actually have to separate them at times because my son will try to sneak her snacks and she love it and him for it!
My dog is a shaggy haired jack Russell terrier, I adobted her when she was 3 years old, when my daughter turned 6 yrs old. My daughter is now 22 yrs old, that makes our Sugar 19 yrs. Old!!! Her eyesight is going, but she still eats well,go to the potty, walks, and because her sense of smell is Great, she can go outside on our 4 acres, and do fine. I do however limit her time to 15 mins:). She does sleep more than she used to.
My girl who is German Shepard mixed with Husky is 14 1/2 years old. She currently has mobility problems with her hind legs..I know her time is getting closer. I dread the day when she must be put down due to pain or mobility problem. That will certainly be a very sad day for me!!
Hi to all of you dog lovers. My 110lb Great Dane cross English Mastiff is 13years,6mth. Shadow has been the love of my life since a puppy. My gentle giant. I think she is on the downhill slope now though. Is being treated for her arthritis and now a urinary tract infection. She still enjoys her daily walk and has a good appetite. I started her on Sashas Blend daily at 4y.o. Maybe this has helped with her health and longevity. I will miss her greatly when she goes to doggy heaven.
my dogs are mixed boxer/lab and are 9 and 11
My dog is 7 years old. He is about 98lbs. He is a mix Great Dane, pitBull at least that what we believe. I can’t imagine my life with out him. He is such a gentle giant so Caring and loving.
My dog is a chihuahua rat terrier mix and is 15 years old! She’s still going strong
