Why Do Small Dogs Live Longer

    Two Small Dogs

    Every dog owner knows that having a pet at your side is the greatest pleasure. Your dog can be your jogging companion, a snuggle buddy, a travel buddy, and a favourite. However, you’ll only spend a few minutes with your best friend in the overall plan, as humans tend to outlive dogs.

    When choosing the right puppy, it’s worth considering the average lifespan of your breed. Different breeds of dogs live longer than other breeds; sometimes, smaller canines last longer than large ones. But what exactly is it about the size that affects the life span of dogs?

    It is widely believed that dogs with smaller breeds live longer lives than larger dogs. The research has back this assertion by comparing the sizes of the different breeds and their average lifespan and concluded that the giant breed, the less its lifespan.

    The reason for this is not well identified, but it is an area that many scientists are examining. It has been proven that the ageing process happens simultaneously for breeds with an average weight of less than 50kg, but larger dogs are slower to decline. Dogs weighing more than 50kg begin to age faster, and the decline is even faster. Large breed dogs are at an increased risk of developing stomach and musculoskeletal disease and are at a higher risk of various cancers. It is believed that selective breeding of breeds that grow bigger has affected the growth hormone production and that decreased amounts of these hormones could make it more likely to suffer from these illnesses. Many breeds with large or massive sizes also have a higher chance of heart disease, which could be related to a challenge in the metabolism of carnitine and taurine. The degree of inbreeding could determine how long a breed’s life expectancy is. Mixed breeds have been proven to slightly increase in average life span compared to similar-sized purebred dogs.

    As a veterinarian who has been practising for more than twenty years, I’ve often been confronted by a simple and seemingly unanswerable issue Why do smaller dogs have longer lives than larger dogs? It’s been for a long time acknowledged and accepted within the world of pet care that teacup poodles in tiny cups last ten or more years than the Great Dane. Both breeds of dogs have the exact genetic blueprint, eat the same food, and reside in homes similar to their own. But one breed can live more than triple the length of time. Why? Recent research sheds illumination on the problem.

    In the April edition of the science journal “The American Naturalist,” biologists from the German University of Gottingen explored the relationship between the size of breeds of dogs and their life lifespan. Researchers looked at data from over 56,000 dogs, representing the 74 breeds in North American veterinary teaching hospitals. The researchers found that larger dogs were ageing more quickly than smaller breeds. The study found that each increase of 4.4 kilograms (2 kg) decreases lifespan by around one month.

    Human Vs. Dog Years

    Knowing what we mean when referring to our dogs’ age is essential. People and dogs get older at different rates. As dogs get 1 year of age, vets believe they’ve matured more than people reached the age of 15. The second year of a dog’s life is around nine years for humans. After that, the dog’s ageing process varies depending on its size and age.

    Dental Health

    According to the Journal of American Animal Hospital Association in the journal of American Animal Hospital Association, Dr Urfer wrote while comparing the health of two breeds, all other aspects being equal, his routine dental cleanings by a vet reduced the chance of dying by around 20 per cent. Doctor. Urfer pointed out that there is a direct link between healthy dental health and general health. However, it may also be the case that pet owners who are careful of their dog’s dental health would be more likely to provide preventive care and veterinary treatment, which can help prolong their pet’s life.

    What Is the Average Lifespan of a Dog?

    The life expectancy of a dog is contingent on the breed of dog they’re in: medium, small or giant dog breed; therefore, the lifespan of a dog varies.

    Small Breed Dogs

    Smaller breeds, such as Chihuahua and Maltese, are more compact. Chihuahua and Maltese, which are well-loved because of their portability, are believed to weigh smaller than (9.07 kg) and have an average lifespan of between 10 and 15 years. The oldest Chihuahua known to exist, Megabyte, who died at 20 and 265 days old.

    Medium and Large Dog Breeds

    Medium-sized dog breeds, such as most spaniel breeds, are around 20- 50 weight (9.07-22.68 kg), and larger breeds, like the well-known Labrador boxer and retriever, are generally considered to be more than fifty pounds (22.68 kgs). The lifespan of large and medium breeds is around 10-13 years.

    Giant Dog Breeds

    The giant dog breeds are believed to weigh over 90 pounds (40.82 kilograms). The typical lifespan for a giant breed, like the majestic Great Dane, is, unfortunately, just 6-8 years old. However, certain breeds have lived to 11-12 years old or more.

    How Do I Make My Dog Live Longer?

    Due to advancements in the field of veterinary science as well as prevention, the longevity of our pets is growing. Our dogs can live longer, healthier lives through:

    • A healthy diet is essential.
    • Encouragement of breed- and physically and mentally active ageing.
    • We take our dogs to annual checkups with our veterinarians and vaccinations.
    • Protecting them from injuries.
    • Offering the love of your life and affection.
