At What Age Is A Dog A Senior


While dogs have shorter lives than humans, that doesn’t mean they age faster. In fact, the first year of a dog’s life is equivalent to about 15 human years. After that, the formula gets a little more complicated because small dogs generally live longer than large breeds. Ultimately, it boils down to understanding your own dog’s needs and knowing when he is officially past his prime. Keep reading to learn more about how old your dog really is in human years and whatever happened to that whole seven-year rule?

Small Dogs

Small dogs are generally considered seniors at 7-10 years old, while larger dogs are considered seniors after 10 years. This is because smaller breeds tend to live longer than larger breeds. Smaller dogs also face more health issues than larger ones. This includes hip dysplasia and other orthopedic problems, as well as eye issues such as cataracts or glaucoma.

Medium Dogs

Next, we’re going to talk about medium-sized dogs. These are a bit bigger than small dogs, but still smaller than large ones. They include dachshunds, corgis, beagles and terriers.

The average lifespan for a breed of medium dog is 10-15 years old; however the oldest recorded dog was 29 years old! That’s nearly two decades of cuddles and kisses from your favorite furry friend.

Large Dogs

The general age for large dogs to be considered seniors is 10. However, this number can vary depending on a dog’s breed and size. In addition to the age of 10, dogs are generally considered seniors when they become middle-aged between the ages of 5 and 8.

If your dog has just turned 10 or is in his/her middle years (5-8), consider all that this means for your senior canine companion:

  • Health problems increase as he/she ages.
  • Care needs increase as he/she ages.
  • Exercise needs increase as he/she ages.
  • Attention needs increase as he/she ages.
  • Grooming requirements also increase with age because stiffer skin may mean more shedding and less hair grows back after being shaved down during grooming sessions which makes it harder to keep clean looking fur coats maintained well enough through regular brushing sessions throughout their lives without having bald patches showing up due to excessive scratching happening during grooming sessions due to dry skin issues causing irritation around sensitive areas where frayed edges tend appear near seams like wrists & ankles while wearing clothing items made out materials such as cotton knit pants!

Depending on their size, dogs are seniors between 7 and 10.

Depending on their size, dogs are seniors between 7 and 10.
