Our pets don’t stay young forever. Eventually, the long walks might get a little shorter, the naps a little longer, and the routines we’ve known for years may start to change.
Ageing is a natural part of life, but getting older doesn’t mean our pets should simply be expected to slow down, feel uncomfortable or lose interest in the things they enjoy.
As dogs and cats enter their senior years, their nutritional and wellness needs can change. Paying attention to those changes and supporting their health along the way can make a meaningful difference to their comfort and quality of life.
So what actually changes as our pets get older, and what can we do to support them?
1. Gut Health: Digestion Changes With Age
Digestion is about more than what goes into the food bowl. The gut is home to a complex community of microorganisms, known as the gut microbiome, that plays a role in digestion, nutrient metabolism and immune function.
As pets age, changes in digestion, appetite, activity and overall health can influence how their digestive system functions.
You might notice:
- Changes in stool consistency or frequency.
- More gas or occasional digestive upset.
- Changes in appetite.
- Increased sensitivity to certain foods.
Supporting digestive health starts with a diet that meets your pet’s individual nutritional needs. Adequate hydration, appropriate fibre and a variety of nutrients all play a role. Probiotics and prebiotics may also be useful in certain situations, depending on the individual pet.
The goal isn’t to add every digestive supplement available. It’s to understand what your pet needs and support their gut accordingly.
2. Cognitive Health: Supporting the Ageing Brain
Have you noticed your older dog becoming a little more confused, restless at night or less interested in familiar activities? Perhaps your cat seems more vocal or doesn’t follow their usual routines.
Changes like these can sometimes be associated with age-related cognitive decline.
Canine and feline cognitive dysfunction can affect memory, awareness, sleep patterns and interactions with family members. Some signs can be subtle at first, which makes them easy to dismiss as normal ageing.
Things to watch for include:
- Changes in sleep patterns, including restlessness at night.
- Confusion or appearing lost in familiar surroundings.
- Changes in social behaviour or interaction.
- Increased anxiety or vocalization.
- Changes in previously learned behaviours.
Keeping the brain engaged is an important part of supporting an ageing pet. Gentle training, scent games, food puzzles, interactive play and familiar routines can all provide mental stimulation.
Nutrition is another area worth considering. Certain nutrients, including omega-3 fatty acids and antioxidants, are being studied for their role in brain health. Some supplements are also formulated to support cognitive function.
If you notice changes in your pet’s behaviour, it’s worth discussing them with your veterinarian. Cognitive changes can overlap with other medical concerns, including pain, sensory loss and underlying illness.
3. Mobility and Inflammation: Keeping Them Moving Comfortably
One of the changes people often associate with ageing is reduced mobility.
Maybe your dog takes longer to get up after a nap, hesitates before jumping into the car or isn’t quite as enthusiastic about longer walks. Cats may stop jumping onto their favourite furniture or spend more time resting in easy-to-reach places.
These changes can be associated with joint disease, muscle loss or discomfort. They’re not something we should automatically accept as an unavoidable part of getting older.
Supporting mobility involves looking at the bigger picture:
- Maintaining a healthy body condition to avoid unnecessary strain on joints.
- Encouraging regular, appropriate movement.
- Providing comfortable bedding and easy access to favourite resting spots.
- Supporting muscle health through appropriate nutrition.
- Discussing ongoing stiffness or discomfort with your veterinarian.
Nutrition can also play a role. Omega-3 fatty acids and certain joint-support ingredients are commonly used in mobility supplements, although the right approach depends on your pet’s health and individual needs.
The goal isn’t necessarily to get an older pet moving like they did at two years old. It’s to help them stay comfortable, maintain strength and continue enjoying the activities they can.
4. Oxidative Stress: Understanding the Role of Antioxidants
This one is a little less obvious, but it’s an important part of understanding the ageing process.
Our pets’ bodies naturally produce unstable molecules called free radicals as part of normal metabolic processes. When free radicals accumulate beyond what the body’s antioxidant systems can manage, oxidative stress can occur.
Oxidative stress is associated with cellular damage and is involved in several processes related to ageing.
Antioxidants help the body manage free radicals. They’re found in a variety of foods and include nutrients such as vitamins C and E, as well as plant compounds called polyphenols.
A varied, nutritionally complete diet provides a foundation for antioxidant intake. Depending on the individual pet, additional nutritional support may also be worth discussing.
It’s important to remember that more isn’t always better. Supplements should be chosen carefully, with attention to ingredient quality, appropriate amounts and your pet’s overall health.
Looking at the Whole Pet
These four areas don’t operate independently. Digestive health, cognitive function, mobility and cellular health are all part of a much bigger picture.
That’s why supporting a senior pet shouldn’t come down to one supplement, one food or one routine.
It means paying attention to changes, reviewing their nutritional needs, keeping them mentally and physically engaged, and making adjustments as their needs evolve.
Regular veterinary checkups are especially important during the senior years. Changes in appetite, thirst, weight, behaviour or mobility can sometimes be early signs of an underlying health concern. Don’t assume something is simply happening because your pet is getting older.
Age is Just One Part of Their Story
Our senior pets have spent years being part of our lives. They deserve the same thought and attention as their needs change.
Sometimes support looks like adjusting their food. Sometimes it’s finding a way to make getting around the house easier, adding a little more enrichment to their day or simply recognizing when they need a slower pace.
There’s no single approach that works for every ageing pet. The best support is the kind that considers the whole animal, their individual needs and the life they’re living right now.
Because getting older is inevitable. But helping them feel their best along the way is something we can keep working towards.
