When is a dog considered a senior?

At what age does a dog become a senior? How can a vigilant dog parent identify signs of aging, and what specific care requirements does an aging dog have? Today's post features answers to these questions from our Grants Pass vets.

How old is a senior dog?

You probably know the concept that equates one human year to seven dog years. However, determining a dog's age is not as straightforward. Different dog breeds age at varying rates.

In general, smaller dogs age more slowly than larger breed dogs. Here's a basic guide:

Small breeds are considered senior dogs when they turn 10 to 12 years old. 

Medium breeds are considered senior dogs when they hit 8 to 9 years old. 

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

Signs That Your Dog is Getting Old

As your dog ages, they will experience both mental and physical changes. Some of these changes, like the development of grey hair around their muzzle, result from the natural aging process and require no specific veterinary care.

However, other changes may necessitate your vet's attention to ensure your dog maintains optimal health and comfort. Keep an eye out for these signs indicating that your dog is aging:

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

Your Senior Dog's Care Requirements 

Take several proactive steps to ensure your pup's comfort and well-being as they age.

Vet Care

Prioritize regular vet visits as the first step in caring for a senior pup. By scheduling routine wellness exams for your senior dog, you enable your vet to screen for emerging geriatric conditions and initiate treatment promptly. Assessing your senior dog's nutrition levels and mobility, your veterinarian will offer recommendations for beneficial adjustments, such as changes in exercise or diet.


A proper diet brings physical benefits and may support your dog's cognitive function as they age. Like humans, dogs can experience dementia or Alzheimer 's-like conditions. Maintaining mental alertness in your dog can be aided by feeding them a diet rich in omega-3 fatty acids and ensuring they exercise correctly.

For senior dogs, various prescription diets and supplements are tailored to address specific health conditions they may encounter. Consult with your vet to determine if a particular diet or supplement is recommended for your pup.

As your dog grows older, their nutritional requirements are likely to change. Senior dogs with reduced activity levels, are more susceptible to weight gain, leading to other health issues, such as joint pain and cardiovascular conditions. Discuss potential adjustments to your dog's daily calorie intake, or consider transitioning to a food specifically designed for weight loss with your vet.

Exercise - Physical & Mental

Senior dogs need both physical exercise and mental stimulation to stay healthy. Don't underestimate the value of teaching your older dog new tricks or introducing them to a new puzzle. Consider options like puzzle chew toys that engage them physically and challenge their minds to earn a treat.

As your dog ages, maintaining a consistent physical activity routine becomes crucial. Regular exercise is key for weight management and joint health in dogs. However, be attentive to signs that your dog may struggle with their usual exercise routine. If long walks are becoming challenging, opt for shorter, more frequent walks to accommodate their needs. Adjusting their daily calorie intake or transitioning to a specially formulated weight-loss dog food may also be necessary for their overall well-being.
