Senior Dog Health Issues & How to Help

Key points:

• Ageing dogs may experience changes in energy, mobility, sleep, weight, appetite, vision and hearing.
• Regular checks can help you spot senior dog health issues such as joint pain, dental disease or cognitive decline earlier.
• Gentle exercise and small changes around the home can make everyday life more comfortable for an older dog.
• Senior dog nutrition should reflect your dog's weight, activity levels and any health conditions they're managing.
• Behavioural changes such as confusion, disrupted sleep or increased anxiety can sometimes signal cognitive decline.
• Regular veterinary care becomes increasingly important as your dog ages, particularly if you notice sudden or unusual changes.

As your dog gets older, you'll notice changes as they age. You might spot more grey hairs, extra naps during the day or slower starts in the morning. These are some of the more obvious signs.

Ageing can also bring a higher chance of health problems in older dogs. Knowing what to look for makes it easier to keep your dog comfortable and healthy well into their senior years.

Keep reading to learn about common senior dog health issues, changes in diet and exercise, and simple ways to support your dog at home.

Signs of ageing in dogs

Most dogs reach senior status at around seven years of age, although larger breeds often get there earlier. Common signs of aging in dogs can include:

• Greying fur around the muzzle and face, especially around the eyes
• Stiffness or reluctance to jump
• Reduced energy or slower recovery after activity
• Changes in sleep patterns or needing more rest
• Cloudier-looking eyes
• Changes in weight
• Changes in appetite or thirst

Some of these are a normal part of ageing, while others can point to an underlying health issue. That's why regular check-ups become more important as your dog gets older.

Common senior dog health issues

Many older dog health issues fall into several common categories, including:

• Arthritis and joint pain: One of the most common senior dog health issues, caused by wear and changes in the joints.
• Cognitive decline: Sometimes called canine cognitive dysfunction, this can affect memory, awareness and behaviour.
• Dental disease: Years of wear can lead to gum disease, tooth loss or infection.
• Vision and hearing loss: These changes can be gradual and subtle, particularly in the early stages.
• Weight changes: Weight loss and weight gain can become more common with age.
• Kidney and organ function decline: Age-related changes can affect how efficiently the body processes nutrients and removes waste.
• Heart disease: Signs can include reduced stamina, coughing, fatigue or heavy breathing at rest.

Not every senior dog will experience all of these, but knowing what to look out for can help you notice changes early and seek support when needed.

Senior dog arthritis and joint pain

Arthritis develops as the cartilage cushioning the joints gradually changes and breaks down, which can cause inflammation, pain and stiffness. You may notice hesitation before jumping, slower walks, stiffness after rest or reluctance to be touched in certain areas.

Practical support can include orthopaedic bedding, ramps or steps for the car and couch, and non-slip mats on slippery floors. Your vet can also advise whether joint supplements or medications may be suitable for your dog.

Cognitive decline in senior dogs

Cognitive decline in senior dogs, sometimes called canine cognitive dysfunction or doggy dementia, can affect memory, learning and awareness. Signs can include:

• Confusion or disorientation in familiar places
• Restlessness at night or disrupted sleep patterns
• Forgetting house training or learned commands
• Increased anxiety or clinginess
• Staring blankly or getting stuck in corners

Changes can be easier to spot over several months than from day to day. Puzzle feeders, scent games and snuffle mats can help keep your dog's brain engaged, while certain diets or supplements may also form part of a vet-recommended support plan.

If you notice behavioural changes, Petstock's vet services can help you investigate possible causes and discuss ways to support your dog's quality of life.

Other changes to watch for

Other changes to look out for include dental problems, vision changes, hearing loss and unexplained weight loss or gain.

Bad breath, reluctance to chew or visible tartar can indicate dental disease. Regular brushing and dental care products can help support oral health between vet visits.

If your dog starts bumping into furniture, seems unusually clumsy or develops a cloudy or bluish appearance in the eyes, it may indicate changes in their vision that need investigating. Declining eyesight can occur in older dogs, and your vet can check for conditions such as cataracts or glaucoma.

Hearing changes are also common. If your dog isn't responding to their name or familiar commands like they used to, it may indicate hearing loss. Speak to your vet about any concerns. Touch or visual cues can also help your dog understand what you're asking, particularly if their hearing is declining.

Weight changes are another important part of senior dog health to monitor. Unexplained weight loss can be linked to dental pain, kidney problems or other conditions, while weight gain may reflect reduced activity or changes in metabolism.

Your vet can assess your dog's body condition and recommend a plan based on their individual needs.

Senior dog nutrition and diet

Senior dog diet needs vary from dog to dog. A senior dog nutrition plan should consider your dog's current health, weight, activity levels and any existing conditions you're managing.

Your vet may recommend dietary changes to support weight management, digestion or other health concerns. Products designed to help support digestion may form part of their routine, depending on your dog's needs.

For dogs experiencing stiffness or joint pain, your vet may also discuss appropriate treatments, which can include prescription medications, injections or joint supplements.

Senior dog exercise needs

Your senior dog may not be as active as they once were, but regular movement is still important. Senior dog exercise needs will vary depending on their mobility and overall health, but gentle walks and short play sessions can help maintain movement and muscle strength.

Avoid activities that put unnecessary strain on sore or arthritic joints, such as repeated jumping or rough play. Let your dog set the pace and adjust their routine if they seem stiff or tired.

How to help a senior dog at home

The good news for senior dog owners is that small, consistent changes can make home life more comfortable.

Choose a diet suited to your dog's age and individual health needs, and keep their mobility up with gentle daily exercise. Adding steps or ramps and non-slip mats can make it easier for dogs with stiff joints to move around safely.

If their vision or hearing is declining, keep furniture, food bowls and other essentials in consistent locations so they can navigate familiar spaces more easily. These simple adjustments can make a big difference to everyday senior dog care.

Senior dog vet care

Regular senior dog wellness checks are an important part of caring for an ageing dog. Your vet may recommend more frequent appointments as your dog gets older, depending on their breed, age and health.

A geriatric dog care appointment may include a physical examination and, where appropriate, additional screening such as blood or urine tests to build a clearer picture of your dog's overall health.

Keeping up with senior dog veterinary care and mentioning any changes in appetite, weight, mobility, behaviour or energy can help your vet identify potential issues and recommend the right support.
