Caring for a Senior Dog: Comfort, Health and Routine

In short
Older dogs often need more regular check-ups, a diet and exercise routine that suits their changing body, and a few small adjustments around the home. Because many age-related changes come on slowly, keeping track of appetite, water, weight and activity helps you notice when something shifts.
When does a dog become senior?
There is no single age at which a dog becomes senior. Size makes a big difference: large and giant breeds tend to age faster and may be considered senior from around six or seven years old, while small breeds often stay in their prime for longer. Your vet is the best person to say when your dog should move to senior care, and opinions vary.
Age is also only part of the picture. Some dogs are lively well into their teens, while others slow down earlier. Look at your dog as an individual rather than focusing on a number.

Regular check-ups
Older dogs can develop health problems that are not obvious at home, so regular vet visits become more important. Many vets suggest check-ups every six months for senior dogs, though the right interval depends on your dog's health. Your vet may recommend blood or urine tests to get a picture of how your dog's organs are working.
Before each visit, it helps to note:
- Any changes in appetite, thirst or toilet habits
- Changes in weight
- Stiffness, slowing down on walks, or reluctance to jump or use stairs
- New lumps, bad breath or changes in behaviour
Between check-ups, contact your vet sooner if you notice anything that worries you. Our guide to signs your pet needs a vet covers what needs urgent attention.
Weight and diet
Many older dogs become less active and need fewer calories, so weight can creep up. Others lose weight because of dental problems, illness or a reduced appetite. Both directions are worth noticing.
- Weigh regularly – every couple of weeks is a good routine for a senior dog, using the same scales.
- Check body condition – you should be able to feel the ribs easily without pressing hard, and see a waist from above. Our pet calculators can help you think about weight and daily food amounts.
- Talk to your vet before changing food – senior diets vary, and dogs with specific conditions may need particular nutrition. If you do switch, do it gradually over a week or so.
- Watch treats – they add up quickly. Use small pieces, or set aside some of the daily food allowance as rewards.
- Make eating easy – softening dry food with warm water can help dogs with sore mouths. A raised bowl may be more comfortable for some dogs with stiff necks.
Joint comfort and gentle exercise
Stiffness and joint pain are common in older dogs, although dogs often hide discomfort. Signs include stiffness after rest, slowing on walks, reluctance to jump into the car, difficulty with stairs, or licking at joints.
Exercise is still important for keeping muscles strong and weight steady, but it may need to change:
- Choose several shorter walks rather than one long one.
- Keep to softer ground where possible, and avoid sudden bursts of running or jumping.
- Let your dog set the pace, and allow time for sniffing, which is mentally tiring in a good way.
- Gentle swimming or hydrotherapy may suit some dogs. Ask your vet first.
- If your dog is stiff or sore the next day, the previous day's exercise may have been too much.
If you think your dog is in pain, speak to your vet. Pain relief and other treatments can make a big difference, and never give human painkillers, some of which are dangerous for dogs.
Dental care
Dental disease is common in older dogs and can be painful. Watch for bad breath, red gums, dropping food, chewing on one side, or pawing at the mouth. Brushing with a dog toothpaste is the most effective home care if your dog will accept it. Your vet can check your dog's teeth at each visit and advise whether a dental procedure is needed.
Cognitive changes
Some older dogs develop changes in thinking and behaviour, sometimes called canine cognitive dysfunction. You might notice:
- Seeming confused or getting stuck in corners
- Restlessness or pacing at night, or changes in sleep pattern
- Toilet accidents in a previously house-trained dog
- Less interest in people, or more clinginess
- Barking or whining for no clear reason
These signs can also be caused by other conditions, such as pain, hearing or sight loss, so it is important to see your vet. Keeping a steady routine, gentle training games, puzzle feeders and new smells on walks can help keep your dog's mind active.
Adjusting your home
Small changes can make daily life easier:
- Put rugs or non-slip mats on slippery floors.
- Use a ramp or step for the car or sofa.
- Provide a supportive, padded bed in a warm, draught-free spot.
- Keep food, water and bed in familiar places, especially if sight is fading.
- Use baby gates to block stairs if your dog is unsteady.
- Allow more frequent toilet breaks.
Older dogs can also cope less well with heat and cold. A coat in winter and extra care in summer may help. See our hot weather safety guide.
Why tracking helps
Many changes in senior dogs happen gradually: drinking a little more, eating a little less, losing a bit of weight, walking a little slower. Because you see your dog every day, these can be hard to notice until they are well established.
Keeping simple records gives you something to compare against. With Petopedia, you can log appetite, water, weight and activity, and your Petopedia dashboard shows how recent days compare with your dog's usual range, along with 30-day trends. This does not diagnose anything, but it can help you spot a change sooner and give your vet clear information. Our guide to knowing your pet's normal explains how to build a baseline.
Above all, enjoy this stage of your dog's life. With a little extra care and attention, many older dogs stay happy and comfortable for years.
