Getting older is not a disease
Every dog ages. It's a natural process, not a medical condition, and with the right care, your dog's senior years can be some of the most rewarding of your time together. Older dogs are calmer, more settled, deeply bonded to their families, and often develop a gentle wisdom that puppy owners can only dream about. But ageing does bring changes that require adjustments to how you care for your dog.

The key to good senior care is early recognition and proactive management. And dogs can't tell you when something hurts, when their eyesight is fading, or when they're feeling confused. They rely on you to notice the changes and respond. This guide covers everything you need to know to keep your older dog comfortable, happy, and enjoying life for as long as possible.
When is a dog considered senior?
There's no single age at which a dog becomes "senior". But it varies by breed and size:
One of our day care dogs, a Boxer, dropped weight gradually over a few months. And the owner hadn't noticed at home, but our team flagged it during a routine check.
- Small breeds (under 10kg): generally considered senior around 10 to 12 years
- Medium breeds (10 to 25kg): around 8 to 10 years
- Large breeds (25 to 40kg): around 7 to 8 years
- Giant breeds (over 40kg): as early as 5 to 6 years
These are guidelines, not rules. Some dogs show signs of ageing earlier, others much later. The important thing is to observe your individual dog and respond to the changes you see, regardless of what any age chart says.
Common age-related changes
Understanding what's normal in ageing dogs helps you distinguish routine changes from problems that need veterinary attention:
Our guide to day care for older dogs covers some related ground.
Mobility changes
Slowing down on walks, stiffness after rest (especially first thing in the morning), reluctance to jump onto furniture or into the car, difficulty with stairs, and a generally less enthusiastic response to exercise are all common signs of age-related joint wear. Arthritis affects a significant proportion of senior dogs, even those who've been fit and active throughout their lives.
Sensory changes
Hearing loss is very common in older dogs and often develops so gradually that owners don't notice until it's quite advanced. Your dog may stop responding to their name, seem startled when you approach from behind, or sleep through noises that used to wake them. Vision changes are also common. A bluish haze in the eyes (nuclear sclerosis) is normal and usually doesn't significantly affect vision, but cataracts and other conditions can cause more serious visual impairment.
Cognitive changes
Canine cognitive dysfunction (the dog equivalent of dementia) affects many senior dogs. Signs include confusion or disorientation in familiar environments, changes to sleep patterns (restlessness at night, sleeping more during the day), forgetting previously learned behaviours, staring into space or at walls, getting stuck behind furniture, and changes in interaction with family members. If you notice these signs, talk to your vet, there are dietary supplements and medications that can help slow progression.
Coat and skin changes
Grey muzzles are the most obvious sign of ageing, but senior dogs often develop thinner coats, drier skin, and are more prone to lumps and bumps (most are harmless lipomas, but all new lumps should be checked by a vet). Regular grooming becomes even more important for senior dogs: gentle brushing stimulates blood flow to the skin, and the hands-on contact helps you spot changes early.
Weight changes
Some senior dogs gain weight as their metabolism slows and activity decreases. Others lose weight as they age, sometimes due to reduced appetite, dental problems, or underlying medical conditions. Monitor your dog's weight regularly and adjust food intake accordingly. Our weight management guide has detailed advice on assessment and adjustment. Especially with puppies.
Mobility support
Maintaining mobility is one of the most important aspects of senior dog care. We've had customers tell us that stiff, painful joints left unmanaged lead to muscle loss, which leads to further joint instability, which leads to more pain, a downward spiral that dramatically reduces quality of life. Proactive management can slow or even partially reverse this process. Especially with puppies.
There's more on this in our guide to dog weight management.
At home
- Ramps and steps: help your dog access the car, sofa, or bed without jumping; jumping impacts joints heavily
- Non-slip surfaces: place rugs or mats on hard floors; older dogs lose confidence on slippery surfaces and may fall, causing injury or fear-based avoidance of certain rooms
- Raised food and water bowls: reduce strain on the neck and shoulders during eating and drinking
- Supportive bedding: orthopaedic memory foam beds distribute weight more evenly and relieve pressure on joints; place them away from draughts and in an easily accessible spot
- Warm and dry: senior dogs feel the cold more; keep them warm, especially after walks
Supplements and medication
Joint supplements containing glucosamine, chondroitin, and omega-3 fatty acids can support joint health in senior dogs. While the evidence is mixed on whether they reverse existing damage, many vets and owners report visible improvements in mobility and comfort. For dogs with diagnosed arthritis, your vet may prescribe anti-inflammatory medication (NSAIDs), which can dramatically improve quality of life.
Never give human painkillers to dogs. Less is more. Paracetamol and ibuprofen are both toxic to dogs. Always consult your vet before starting any supplements or medications.
Hydrotherapy
Hydrotherapy (swimming or underwater treadmill therapy) is one of the most effective treatments for senior dogs with joint problems (it's more common than you think). Less is more. The buoyancy of water supports the body while allowing full range of motion, building muscle strength without the impact stress of land-based exercise. Many senior dogs that struggle on walks flourish in the hydrotherapy pool. Ask your vet for a referral. Most areas have qualified canine hydrotherapists.
Mental stimulation for ageing minds
Mental stimulation is at least as important as physical exercise for senior dogs, and arguably more so. An active mind stays sharper for longer, and enrichment activities provide satisfaction and engagement even when physical capacity is declining.
- Sniff walks: slow, meandering walks where your dog leads and investigates at their own pace; the nose doesn't age like the joints do, and scent work is one of the most mentally enriching activities any dog can do
- Food puzzles: scatter feeding, stuffed Kongs, snuffle mats, and puzzle feeders make mealtimes into brain games
- Gentle training: senior dogs can absolutely learn new things; short, positive training sessions keep the mind engaged and strengthen your bond
- Social interaction: time with other dogs (calm, compatible ones) and with people provides emotional enrichment that prevents isolation and depression
- New experiences: even small changes of routine, new walking routes (kept short), or visits to new places provide novelty that stimulates ageing brains
Our day care can be adapted for senior dogs. Shorter sessions, gentler play groups matched by energy level, and enrichment activities designed for older dogs keep them engaged and social without overtaxing them physically.
Diet adjustments
Senior dogs have different nutritional needs than younger adults:
- Protein: contrary to the old advice of reducing protein for seniors, current veterinary nutrition guidance recommends maintaining or even increasing high-quality protein to preserve muscle mass
- Calories: reduce overall calories if your dog is less active, to prevent weight gain; but monitor closely and increase if your dog is losing weight
- Joint supplements: many senior diets include added glucosamine and omega-3; alternatively, supplement separately
- Fibre: slightly increased fibre helps with the digestive slowdown common in older dogs
- Hydration: older dogs sometimes drink less; wet food, adding water to kibble, or using water fountains can help maintain hydration
Talk to your vet about whether a specific senior diet is appropriate for your dog. Not all "senior" foods are created equal, and your vet can recommend one that matches your dog's specific needs.
Vet check schedule
Senior dogs should see the vet more frequently than younger adults. Timing matters. A twice-yearly check-up is the minimum recommendation for dogs over 8 years old. Many conditions common in older dogs. Dental disease, kidney problems, heart disease, thyroid issues, develop gradually and are much more manageable when caught early.
Blood and urine tests at annual or twice-yearly intervals give your vet a baseline to track changes over time. At our day care, we keep a close eye on every dog's health, and a result that's technically within normal range but has shifted significantly from the previous year can be an early warning sign that wouldn't be caught without regular monitoring.
Gentle exercise options
Senior dogs still need daily exercise: just less intense and more thoughtful than in their younger years:
- Shorter, more frequent walks: two or three 15 to 20 minute walks spread through the day are better than one long outing
- Soft surfaces: grass, woodland paths, and sand are much kinder on ageing joints than pavement
- Let your dog set the pace: if they want to stop and sniff every lamppost, let them; if they want to turn for home, turn for home
- Swimming: low-impact and joint-friendly, ideal for dogs that enjoy water
- Gentle play: short games of gentle fetch (rolling the ball rather than throwing it), tug (let them win), or find-the-treat keep them active without strain
- Secure fields: our enclosed dog fields let senior dogs potter at their own pace in complete safety
Enrichment ideas for less mobile dogs
For senior dogs whose mobility is significantly limited, enrichment becomes the primary way to maintain quality of life:

- Scatter feeding in the garden. Even slow, gentle searching is rewarding
- Snuffle mats. Hide treats in the fabric for nose-driven foraging
- Frozen Kongs, stuff with soft food and freeze for extended, satisfying licking
- Short car rides. A change of scenery, even from the car, provides mental stimulation
- Visits from friends (human and canine): social interaction at home when walks are limited
- Gentle massage. Many senior dogs love a slow, careful massage; it provides comfort and strengthens your bond
Key takeaways
- Senior age varies by size: giant breeds age faster than small breeds; observe your individual dog
- Mobility management is crucial: ramps, non-slip surfaces, orthopaedic bedding, and joint supplements make a real difference
- Mental stimulation matters more than ever: sniff walks, puzzles, and gentle training keep ageing minds sharp
- See the vet twice a year: early detection of age-related conditions dramatically improves outcomes
- Adjust food, not just exercise: senior dogs need different nutrition; talk to your vet
- Quality of life is the priority, a comfortable, engaged, loved senior dog is a happy senior dog
