As dogs grow older, they undergo both physical and behavioural changes, and these transformations can manifest in myriad ways. A deep understanding of these shifts will empower pet owners to provide their companions with a rich, fulfilling life, even in their golden years. It’s a good idea for any dog owner to learn about these behavioural changes and some practical strategies for managing them effectively.

Understanding the Ageing Process in Dogs

Before diving into the specifics of behavioural changes, it’s important to understand how dogs age. Like humans, dogs experience physiological alterations as they get older, affecting their senses, mobility, and cognitive functions. Ageing rates depend largely on breed and size; smaller dogs like Shih Tzus tend to live longer and age slower compared to larger breeds.

Recognising Behavioural Changes

Decreased Activity Levels

One of the most apparent changes in senior dogs is a decrease in energy levels and overall activity. This can result from a variety of factors including arthritis, muscle weakness, diminished cardiovascular fitness, and general lethargy associated with ageing.

You may notice your dog taking longer to stand up, hesitating before stairs, or simply sleeping more.

Changes in Sleep Patterns

Many older dogs experience shifts in their sleep patterns. You might find that your dog sleeps more during the day and becomes restless at night. This could be due to discomfort from medical conditions like arthritis or a decrease in cognitive function leading to a reversal of their sleep-wake cycle.

Altered Social Behaviour

Some dogs may become less social as they age. Interactions with other dogs and people may decrease, and your previously outgoing pet may prefer quiet corners over engaging in play. In contrast, some dogs may become clingy, showing signs of anxiety when left alone.

Cognitive Dysfunction

Just like humans, dogs can suffer from cognitive dysfunction as they age, which can lead to behaviours resembling dementia or Alzheimer’s in humans. Symptoms can include disorientation, altered sleep patterns, house soiling, reduced interaction, and changes in activity levels.

Changes in Appetite

Senior dogs may display changes in appetite and dietary habits. Some dogs might eat less due to dental issues, decreased sense of smell, or underlying health issues. On the other hand, some may seem hungrier due to certain medical conditions or medications.

Strategies for Managing Behavioural Changes in Senior Dogs

Knowing the behavioural changes is only half the story; understanding how to manage these changes ensures that your pet lives out its senior years comfortably and happily.

Regular Veterinary Check-ups

Frequent veterinary visits are crucial to monitor your dog’s health as it ages. Your vet can catch early signs of diseases that can affect behaviour, such as arthritis, diabetes, or cognitive dysfunction. They can also advise on appropriate dietary changes, exercise routines, and mental stimulation activities.

Modify Their Environment

As your dog’s mobility decreases, consider modifying your home to make it more comfortable. This might include using pet-friendly ramps for stairs or furniture, providing orthopaedic beds, or placing food and water bowls at a comfortable height. It’s also essential to ensure that the home environment remains familiar and consistent, as changes can confuse an ageing dog.

Maintain a Balanced Diet and Regular Exercise

A balanced diet is crucial for maintaining health and managing age-related conditions. Senior dogs often require food that’s high in fibre and lower in calories and fat. Regular, gentle exercise, tailored to your dog’s ability, will help maintain healthy weight and joint mobility.

Mental Stimulation

Keeping your dog mentally stimulated is crucial in combating cognitive decline. Puzzle toys, new training tricks, and social interactions can help keep your dog’s mind sharp.

Medication and Therapies

In some cases, medication may be necessary to manage certain age-related conditions. Therapies such as acupuncture, massage, and hydrotherapy can also support physical health and comfort.

Affection and Comfort

Above all, older dogs require just as much love, attention, and comfort as they did when they were younger. Regular grooming, gentle massages, and simply spending time with them can greatly enhance their quality of life.


While it may be challenging to watch your beloved pet grow older and witness the accompanying behavioural changes, remember that this is a natural part of the life cycle. With proper understanding, patience, and care, you can help your pet navigate these changes and ensure that their senior years are filled with comfort and contentment.
