Signs your senior dog is healthy: What good ageing really looks like

Older dogs hold a special place in our hearts! These pets have been family members for years, so it’s natural to care deeply about their well-being as they age. Owning a senior dog can be a rewarding and joyful experience, but we also recognise that uncertainties can creep in, particularly around health and care.

So, we’ve decided to put together this practical guide to help! While vet check-ups are irreplaceable, knowing the signs of a healthy senior dog between appointments will help ensure your pet is on the right track. Read on to find out how to do a senior dog health check, as well as explore how to keep a senior dog healthy.

What does healthy ageing look like in a senior dog?

Healthy ageing is a natural process, so we need to get comfortable with how that might look. Any changes in your pet should be gradual and may include –

• More grey hairs, especially around the muzzle
• A slight reduction in stamina
• Sleeping a little more than normal
• Slight non-painful clouding of the eyes (nuclear sclerosis)
• A gradual reduction in hearing is possible

However, your senior dog should still have plenty of good days, showing normal levels of interest in people, food, and activities. A healthy senior dog will still engage with the world around them and shouldn’t be experiencing any distress.
 
The age at which a dog is considered senior depends on their size and breed. Giant breeds have a shorter lifespan than smaller ones, so they will reach their senior years at around 5 or 6 years of age. Whereas a small breed dog may not start to show signs of aging until they reach 10 or 11 years. So this should also be factored in when considering healthy ageing in dogs. Take a look at our blog on "what age is a senior dog?" 
 
Remember, age in itself is not an illness, and many older pets can lead healthy and fulfilling lives.

Signs your senior dog is healthy — a head-to-tail checklist

What does a healthy older dog look like? Let’s start at the head and work our way back to the tail!

Eyes

Eyes should be comfortable with no inflammation or excessive discharge. A senior pet may have a slight blue haze to their eyes, due to a non-painful condition called nuclear sclerosis (or lenticular sclerosis). This shouldn’t affect your pet’s vision too much.

Teeth

Dental disease is common in older pets, but shouldn’t be accepted as normal. Your pet’s teeth should be clean with minimal tartar and pink gums (not red or pale). Their breath should not be offensive.

Ears 

Ears should be clean and not inflamed or sore. Some loss of hearing can occur as pets age, but this should be gradual and not accompanied by any other signs like head shaking or increased itchiness.

Brain (mentation) 

A healthy senior dog will be bright and engaged with the world. They will be keen to interact with people, play with toys, and participate in activities. Sleep patterns should be largely unchanged, though you may find your pet rests a little more than they used to.

Chest 

Your pet's breathing should be steady, with no increased effort, especially when they are resting. A persistent cough, change in breathing pattern, or increased breathing noise could indicate a problem.

Abdomen 

Your senior pet’s stomach should not be painful, bloated, or enlarged. A pot-bellied appearance can be an indicator of an underlying health issue.

Joints 

A healthy senior dog may start to experience some joint stiffness as they age, but joints shouldn’t be thickened or painful. Limping, struggling to jump up, slowing down on walks, changes in mood, or marked stiffness after sleeping are often indicators of arthritis.

Skin and coat

Should still be in good condition, with minimal scurf or hair loss. Excessive scratching, dandruff, hair loss, or inflammation are not normal signs. Skin lumps are common in senior pets, but should be investigated.

Weight 

Your pet should have a stable weight with a normal body condition. This means being able to feel their ribs relatively easily, with a nipped-in waist. If your pet is losing or gaining weight, this must be explored.

Tail 

A senior dog will have a waggy tail! A healthy elderly pet will have a good quality of life, being able to engage in pleasurable activities, such as playing, eating, and spending time with their owners.

Appetite 

A senior pet will have a good appetite and be interested in food.

Thirst 

Drinking should be consistent. A sudden increase in water intake is something that needs investigating.

Activity levels 

Movement is still comfortable, and a healthy senior pet can get up from rest without too much difficulty. Walks may be a bit shorter than they used to be, but your pet should still be keen to exercise.

Toileting behaviour 

Stools must have a normal, formed consistency that is neither too hard nor too soft. While the odd abnormal stool is not usually a problem, persistent changes should be explored. Take a look at our dog poo chart. Accidents in the house are not considered normal and should be investigated by your vet.

How to do a simple health check on your senior dog at home

We’ve listed all the things that indicate your senior dog is healthy, but how do you put that into practice?
 
It’s a good idea to do a regular home health assessment. While this will never replace a proper veterinary checkup, it will help you to spot developing problems and seek help earlier.
 
You will probably check things like teeth and skin lumps on a regular basis anyway, as part of your normal grooming regime. But it’s worth occasionally doing a more detailed check over. This can be a great bonding exercise - many pets enjoy a bit of extra TLC!
 
At least once a month, we recommend –

• Checking your pet’s mouth carefully, looking at their teeth and gum colour
• Checking their eyes and ears for any discharge or signs of discomfort
• Observing your pet’s breathing when they are at rest, to make sure it is not rapid or laboured
• Running your hands over their body to feel for any new lumps or bumps
• Assessing your senior dog’s body condition score (if you’re not sure how to do this, then speak to your veterinary team), as well as weighing them

This health assessment will probably take you less than 5 minutes. If you spot anything you aren’t sure about, then make sure to contact your vet for an appointment.

How active should a senior dog be?

Exercise needs will vary by breed and size, as well as your pet’s overall health, so follow your dog.
 
Most vets advise regular, moderate amounts of exercise for older dogs. Shorter and more frequent walks are better than one long one.
 
Owners should also choose low-impact exercise over intense activities, for example, gentle swimming and walks at your dog’s own pace, rather than repetitive ball chasing or enforced jogs. This will be kinder on ageing joints.

How to keep your senior dog healthy — proactive steps that make a difference

Regular vet check-ups

Twice-yearly check-ups are recommended for senior dogs. This allows any developing problems to be detected and treated sooner.

Senior-appropriate nutrition

Choose a diet that supports a senior dog’s needs. Generally, this includes adjusted protein for muscle maintenance, controlled phosphorus for kidney health, and Omega-3s for joint and coat health. However, your pet may have a specific health concern that needs more tailored nutrition. Speak to your vet for recommendations if you aren’t sure which senior diet to pick.

Joint and mobility support

Joint issues are common in senior dogs, so take a pro-active approach and aim for low-impact exercise, an appropriate body weight, and targeted senior dog joint supplements. You should also speak to your vet for advice, in case your pet may also benefit from anti-inflammatories or other pain relief.

Mental enrichment 

Cognitive health is extremely important to dogs, just as it is in people. Short sniff walks, gentle puzzle feeders, new training exercises, and a regular daily routine will all support a senior dog's mental well-being.

Dental care

Dental disease affects many dogs over the age of seven and has knock-on effects on heart and kidney health. Regular brushing, dental sticks, and annual dental checks are advised.

Coat and skin care 

Regular gentle grooming helps owners spot changes early and supports skin health. Omega-3 supplementation can support coat condition in older dogs.

Signs to watch for alongside the healthy ones

We’ve touched on a few things to keep a watch out for over the course of the article, but here’s a list of symptoms that should trigger a more urgent vet appointment –

• Weight loss
• Changes in thirst or appetite
• Excessive panting, coughing, or laboured breathing
• Limping, difficulty jumping up
• Repeat episodes of vomiting and diarrhoea
• Changes in personality or odd behaviours like walking in circles, pacing, or increased vocalisation

Conclusion

Healthy ageing in dogs should be celebrated! With the right care and attention, these senior dogs will continue to reward us with their loyalty and companionship for many years to come. Hopefully, our senior dog health check will help you to spot and deal with any emerging problems earlier on.
