Senior Pet Care: Keeping your old furry friends healthy.

Updated: Mar 29

As much as we hate to see it, our pets grow old, and eventually need extra care and attention to maintain their overall health. It is important to remember that age is not a disease and although your pets develop age-related diseases as they age, there are ways to maintain their health through these moments. This can mainly be done through regular vet examinations and lifestyle accommodations.

When are pets considered seniors?

This answer varies for different animals. Cats are considered to be senior after they reach 10 years of age, while dogs vary due to their variation in size. Larger dogs tend to have shorter life spans than smaller dogs. According to the AVMA, pets are considered senior once they reach the last 25% of their estimated lifespan, which translates to the following ages:

  • Small toy breeds (less than 20 pounds): 8-11 years

  • Medium-sized (20-50 pounds): 8-10 years

  • Large breeds (50-90 pounds): 8-9 years

  • Giant Breeds (more than 90 pounds): 6-7 years

Common signs of aging in pets

Many visual and behavioral signs can inform you of your pet's deteriorating health as they grow older. While some may be obvious, others may not be, which is why it is important to monitor your pet's health once they start getting older. Common signs of aging include:

  • Arthritis (stiff joints, favored leg, difficulty standing, resisting being touched)

  • Pain or discomfort

  • Worsening Vision or Hearing

  • Cognitive dysfunction (Increased reaction to loud noises, anxiety, confusion)

  • Increased Wandering

  • House Soiling

  • Changes in Sleep Patterns

  • Less Interest in playing

  • Repeated actions

  • Decreased Response to voice commands

If your pet is showing any of these signs, contact or make an appointment with your veterinarian to discuss these changes and if they are warning signs for disease. Certain diets and foods can help support brain function in senior animals, and your vet can help you decide which one is best for your pet.

Diseases in Senior Pets

As stated above, senior pets' immune systems are weaker than younger pets, making them more susceptible to diseases that can decrease their quality of life or lead to death. Your pet's body changes on the inside just as much as it changes on the outside as it ages. Common diseases in senior pets include:

  • Liver Disease

  • Diabetes

  • Kidney Disease

  • Heart Disease

  • Obesity

  • Joint or bone disease

If left untreated, many of these diseases can be fatal, so it is important that you contact your veterinarian if your pet is displaying any unusual behavioral signs that are concerning. Catching early signs of disease can increase the chances of your pet living to the full extent of its expected lifespan.

What you can do to maintain your senior pet's health

Senior pets are more vulnerable to aging-related issues, including certain diseases. They require more overall attention than younger pets, as changes in behavior are unavoidable, and can inform you on what kind of care your older pets need. In general, senior pets require the following to keep up their quality of life:

  • Increased Veterinary care and bloodwork: Visit the vet twice or more a year and get bloodwork done

  • Altered Diet and nutrition: Provide food that is easier to digest and provides more energy

  • Weight Control: Weight gain and loss are signs of concern and can increase the risk of health problems

  • Parasite Control: Senior pets have weaker immune systems and cannot fight parasites as easily

  • Vaccination: Senior pets have different vaccination requirements than younger pets

  • Maintaining Mobility: Keep pets healthy through appropriate exercises

  • Mental Health: Interact with them to keep their minds stimulated as their cognitive abilities slow down

  • Altered Environment: Adjust their living spaces to reduce the risk of injury (Ex. limiting stair access, orthopedic beds, raised feeding platforms, pet stairs or ramps)

  • Reproductive Diseases: Non-neutered/non-spayed pets are at higher risk of contracting breast, prostate, and testicular cancer.


Age is not a disease, and it is important to remember that as your pet gets older, it will face challenges to its health, and it is up to you to help them through whatever they go through. It is key to monitor their behavior as they age for anything strange, so you can accommodate them and catch any early signs of disease.
