Common Chronic Conditions in Senior Dogs
As dogs grow older, it is normal for their health needs to change. Many senior dogs live happy, comfortable lives for years with the right care, regular monitoring and, where needed, ongoing treatment. Understanding the most common chronic conditions in older dogs can help owners spot early signs, seek veterinary advice promptly and support their pet’s quality of life at home.
In this article, we look at some of the health conditions more often seen in senior dogs, what symptoms to watch for, and the kinds of treatment and support that may help.
This article is intended for general guidance only and should not replace professional veterinary advice. If your pet is unwell or showing concerning symptoms, please contact your veterinary surgeon.
When is a dog considered senior?
There is no single age that suits every dog. Smaller breeds often reach their senior years later than large or giant breeds, which tend to age more quickly. Many dogs are considered senior from around seven years old, but some may show age-related changes earlier or later.
Regular check-ups become especially important as dogs age. Senior health checks can help detect problems earlier, sometimes before obvious symptoms appear.
Why chronic conditions are more common in older dogs
As dogs age, the body naturally becomes less efficient at repairing wear and tear. Joints may stiffen, organs may not work as effectively, and long-term conditions can develop gradually over time. Some illnesses are very manageable if found early, which is why owners should keep an eye out for subtle changes in behaviour, appetite, drinking, mobility and toileting habits.
Osteoarthritis and joint problems
One of the most common chronic conditions in senior dogs is osteoarthritis. This is a progressive condition where the joints become inflamed and painful, often due to wear and tear over time.
Signs to watch for
- Stiffness, especially after rest
- Slower walks or reluctance to exercise
- Difficulty getting up, climbing stairs or jumping
- Limping or uneven movement
- Changes in mood, irritability or reduced interest in play
Treatment and support
Your veterinary surgeon may recommend pain relief, anti-inflammatory medication, weight management, controlled exercise, physiotherapy or joint-supporting supplements. Some dogs benefit from combination care rather than one single treatment.
At home, practical changes can make a real difference, such as non-slip mats, supportive bedding and ramps for getting into the car. If your dog needs ongoing support, you can explore dog joint care products and, where prescribed by your vet, appropriate dog pain relief products.
Dental disease
Dental disease is very common in older dogs and can cause ongoing pain, bad breath and difficulty eating. It often starts with plaque and tartar building up on the teeth, leading to gum inflammation and infection.
Signs to watch for
- Bad breath
- Red or bleeding gums
- Difficulty chewing
- Dropping food
- Reduced appetite
- Swelling around the mouth
Treatment and support
Your vet may recommend a dental examination, scale and polish under anaesthetic, tooth extractions if needed, and a home dental care plan. Daily brushing is ideal, but dental chews, rinses or specially designed products may also help where suitable.
You can find helpful options in our dog dental range, but it is always best to ask your veterinary surgeon which products are most appropriate for your dog’s mouth and overall health.
Chronic kidney disease
Kidney disease becomes more common in older pets, including dogs. The kidneys help filter waste products from the blood, and when they are not working properly, dogs can become unwell over time.
Signs to watch for
- Drinking more than usual
- Urinating more often
- Weight loss
- Reduced appetite
- Vomiting
- Lethargy
Treatment and support
Although chronic kidney disease cannot usually be cured, it can often be managed. Treatment may include a prescription renal diet, medications to control nausea or blood pressure, and regular blood and urine checks. Early diagnosis is especially helpful.
If your dog has been prescribed medication by your vet, you can view our dog prescription products. If you are unsure how the process works, our guide on how to order a prescription medicine and our prescription FAQs may be useful.
Heart disease
Older dogs, particularly some small breeds, can develop chronic heart disease. One common example is degeneration of the heart valves, which can affect how efficiently the heart pumps blood.
Signs to watch for
- Coughing, especially at night or after exercise
- Reduced stamina
- Breathlessness
- Fainting episodes
- Restlessness
Treatment and support
Many dogs with heart disease can do well for a long time with regular monitoring and medication. Your vet may recommend scans, chest X-rays or blood pressure checks. Never start or stop heart medication without veterinary advice.
For dogs on long-term treatment plans, our dog heart products section may help owners source prescribed medications and supportive items more conveniently.
Canine cognitive dysfunction
Some senior dogs develop age-related changes in brain function, sometimes compared to dementia in people. This is known as canine cognitive dysfunction.
Signs to watch for
- Confusion or seeming disorientated
- Sleeping more in the day and waking at night
- Staring into space
- Forgetting routines
- House soiling
- Reduced interaction with family members
Treatment and support
If you notice these changes, speak to your vet, as similar signs can also be linked to pain, poor eyesight, hearing loss or other illness. Support may include environmental changes, routine, enrichment, diet adjustments and, in some cases, medication or supplements.
Soft lighting at night, easy access to beds and toilets, and keeping furniture in familiar places can help some dogs feel more settled.
Diabetes and other hormone-related conditions
Senior dogs can be more likely to develop endocrine conditions, which affect hormone production. Common examples include diabetes mellitus and Cushing’s disease.
Signs to watch for
- Increased thirst
- Increased urination
- Changes in appetite
- Weight loss or weight gain
- Pot-bellied appearance
- Skin or coat changes
Treatment and support
These conditions need veterinary diagnosis and careful long-term management. Treatment may involve insulin injections, tablets, diet changes and regular blood monitoring. With good control, many dogs continue to enjoy a good quality of life.
You can browse our dog endocrine products if your vet has recommended ongoing treatment or support.
Chronic skin and coat problems
Older dogs may also experience ongoing skin issues, including dry skin, recurrent infections, allergies or lumps that need monitoring. While not every lump is serious, any new lump, change in size, or sore area should be checked by your veterinary surgeon.
Signs to watch for
- Itching or licking
- Hair loss
- Red or flaky skin
- Recurrent ear problems
- Lumps or bumps
Treatment and support
Treatment depends on the cause and may include medicated shampoos, prescription treatments, parasite control, dietary support or allergy management. Regular parasite prevention remains important even in older dogs. You can explore our dog skin and coat products and dog flea and worming products as part of a prevention plan agreed with your vet.
Urinary problems and incontinence
Senior dogs may develop urinary issues, including urinary tract infections, bladder stones or age-related incontinence. Incontinence means leaking urine without meaning to, and it can be distressing for both pet and owner.
Signs to watch for
- Dribbling urine while resting
- More frequent toileting
- Straining to urinate
- Blood in the urine
- Accidents indoors
Treatment and support
Because urinary signs can have several causes, a veterinary examination is important. Treatment may include medication, investigation of underlying disease, dietary changes or management of infection.
If your dog is on long-term support, our dog urinary products collection may be helpful alongside your vet’s advice.
How owners can support senior dogs at home
Simple daily care can make a big difference to an older dog’s comfort and wellbeing.
- Keep up with regular veterinary check-ups
- Monitor appetite, thirst, weight and toileting habits
- Maintain a healthy body weight to reduce strain on joints and organs
- Use soft bedding and easy-access sleeping areas
- Provide gentle, regular exercise suited to your dog’s ability
- Continue preventative care such as flea, tick and worm treatment
- Ask your vet before starting supplements or over-the-counter products
Some owners also find it useful to keep a simple diary of symptoms, medication times and any changes they notice. This can be very helpful during veterinary appointments.
When to contact your veterinary surgeon
You should arrange a veterinary appointment if your senior dog shows any ongoing or unexplained changes, especially:
- Drinking or urinating more than usual
- Weight loss or reduced appetite
- Persistent coughing
- Difficulty walking or signs of pain
- Vomiting or diarrhoea that does not settle
- Confusion, collapse or behaviour changes
- Any new lump or rapidly changing lump
Early assessment can often lead to better long-term management and improved comfort for your dog.
