When Is a Dog Considered a Senior?

When Is a Dog Considered a Senior?

Today, our Gilbert vets discuss at what age is a dog considered to be a senior, how to spot signs of aging, and the special care requirements that an aging dog may need.

How Old is a Senior Dog?

You're probably familiar with the notion that one human year is equivalent to seven dog years. It's not quite that simple. Specific dog breeds age at a different pace compared to others.

In general, smaller dogs do not age as quickly as large breed dogs. Here is a general guide:

Small breeds are considered senior dogs around 10-12 years old.

Medium breeds are considered senior dogs around 8-9 years old.

Large and giant breeds are considered senior dogs around 6-7 years old.

Signs That Your Dog is Getting Old

You will notice both physical and mental changes in your dog as they get older. While some of these changes are due to the natural process of aging and don't need any specific vet care, other changes may require veterinary attention to ensure your dog maintains their health and comfort as much as possible.

Some signs that your dog is getting older include:

  • White hairs on the muzzle and face
  • Vision and/or hearing loss
  • Weight gain or loss
  • Gum disease or tooth loss
  • Loss of muscle tone
  • Arthritis and joint issues
  • Reduced liver, kidney, and heart function
  • Sleeping more or difficulty sleeping
  • Reduction of mental acuity

Care Requirements for Your Senior Dog

There are several things you can do to help your dog maintain their comfort and well-being as they get enter their golden years.

Vet Care

The first step to caring of your senior dog is to make sure they attend their routine exams.  Going to your vet regularly allows your vet to screen for any emerging geriatric conditions and begin treatment as soon as possible. Your veterinarian will assess your senior dog's nutrition levels and mobility and provide recommendations for any adjustments that would benefit your dog such as exercise or diet changes.


Besides the physical benefits of a good diet, proper nutrition may be able to help your dog maintain their cognitive function as they age. Dogs can suffer from dementia or Alzheimers-like conditions , just like humans. Feeding your dog a diet that is high in omega-3 fatty acids, along with providing them with proper exercise, may help them maintain mental alertness.

There is also a range of prescription diets and supplements available for senior dogs that are targeted to the various health conditions that senior dogs experience. Speak with your vet to see if they recommend a specific diet or supplement for your pup.

As your dog ages, their nutrition needs will likely change. As senior dogs slow down and exercise less, they become more prone to weight gain. Excess weight gain can cause other health issues, including joint pain and cardiovascular conditions. Speak to your vet about adjusting your dog's daily calorie intake or switching to a food that is specifically formulated for weight loss.

Physical & Mental Stimulation

Along with regular physical exercise, it is important that senior dogs also receive some sort of mental stimulation. It's never too late to teach your pup a new trick. Try bring home a new puzzle designed for pets. There are lots of options for problem-solving activities for dogs such as a puzzle chew toy that will encourage your dog to exercise their mind in order to get a treat.

As your dog ages, it is important that they keep up with a regular schedule of physical activity. Regular exercise helps dogs maintain a healthy weight and keeps their joints healthy.

You may have to adjust the forms of exercise you are providing for your pup. For example, if you notice your dog is having difficulty with the long walks, try taking your dog for more frequent walks that are shorter in duration.
