“They’re just old” is often wrong.

Ageing changes pets, obviously. They may sleep more, move more slowly, or need a bit more support than they used to. But a lot of the things owners get told are “normal ageing” are actually signs of pain, disease, discomfort, or decline that can often be improved. Not always cured. Not always reversed. But improved enough to give a pet more comfort, better function, and sometimes more good-quality time.

That is the real goal with senior pets: not just lifespan, but healthspan. In other words, how well they feel while they are here.

1. Slowing down, stiffness, or reluctance to jump

This is one of the biggest ones. Owners often notice their dog no longer wants to jump into the car, hesitates on stairs, slips more often, or seems stiff after rest. Cat owners may notice their cat stops jumping onto favourite furniture, uses steps instead of leaping, grooms less, or starts having litter tray issues. These are commonly blamed on “old age”, but osteoarthritis and chronic pain are extremely common in senior pets and are often underdiagnosed.

Pain changes behaviour. It changes movement, sleep, tolerance, grooming, confidence, and willingness to interact. A pet in pain may not cry out. They often just do less.

2. Bad breath, dropping food, chewing differently, or avoiding hard food

Dental disease is another thing that gets normalised far too easily. Bad breath is not just “dog breath” or “old pet breath”. It is often a sign of periodontal disease, oral infection, inflammation, or pain. Some pets keep eating despite significant dental pain, which is why owners can miss it. Others start chewing on one side, dropping food, taking longer to eat, avoiding hard treats, or becoming head-shy.

Chronic dental pain affects more than the mouth. It affects appetite, mood, behaviour, and overall wellbeing. If a senior pet seems grumpier, fussier with food, or less interactive, their mouth is worth checking.

3. Confusion, restlessness, changed sleep patterns, or getting “stuck”

Not every older pet with behaviour change has cognitive dysfunction, but it is something worth thinking about. Owners may notice pacing at night, staring into corners, seeming unsettled, forgetting routines, vocalising more, or appearing disoriented in familiar spaces. Some pets become clingier. Others withdraw. Some seem to get lost in the house or stand at the wrong side of a door.

These changes can be subtle at first, and they are easy to dismiss. But they matter. Cognitive decline, pain, sensory loss, anxiety, and medical disease can all overlap, so a proper assessment helps work out what is actually going on.

4. Weight loss, muscle loss, or a change in appetite

A senior pet losing weight is never something to wave away. Even if they still seem bright. Even if they are still eating. Weight loss can be linked to dental disease, kidney disease, gastrointestinal disease, endocrine disease, cancer, chronic pain, or cognitive change. Sometimes what owners notice first is not the number on the scales, but a sharper spine, a bonier face, weaker back legs, or reduced stamina.

Muscle loss matters too. It affects mobility, balance, strength, and recovery from illness. In older pets, small changes add up quickly.

5. Chronic itch, greasy skin, recurrent ear problems, or coat decline

Skin disease is not just a cosmetic nuisance. Chronic itch, recurrent infections, greasy coat, hair loss, odour, or repeated ear issues can seriously affect comfort and sleep. Older pets may also struggle more because their skin barrier, immune function, grooming ability, or mobility is not what it used to be. If a senior pet is constantly licking, scratching, rubbing, or developing repeat flare-ups, that is not something to write off as “just allergies” or “just getting old”.

Chronic skin disease can quietly wear pets down. It also wears owners down. The good news is that many cases can be managed much better once the pattern is properly assessed.

A practical senior wellness framework

A good senior check should be more than a quick listen to the chest and a vague “they’re doing well for their age”. For me, a useful senior wellness framework includes:

• Home mobility check: how the pet rises, walks, turns, uses stairs, jumps, settles, and moves in their normal environment
• Pain screening: looking for subtle signs of osteoarthritis, spinal pain, dental pain, and behaviour changes linked to discomfort
• Dental review: checking the mouth, breath, chewing behaviour, and signs of oral pain or infection
• Nutrition assessment: appetite, weight trends, muscle condition, treat intake, supplements, hydration, and whether the current diet still fits the pet
• Tailored monitoring: deciding what needs watching, what needs testing, and what should be reviewed sooner rather than later

This is one reason in-home assessments can be so useful for senior pets. You get context that is easy to miss in a clinic. You can see how the pet actually moves on their own floors, where they sleep, how they access food and water, whether the litter tray or steps are still working for them, and what daily life really looks like. For anxious, sore, elderly, or mobility-impaired pets, removing the stress of travel and the clinic environment can also make the assessment more accurate.

The point is not to chase perfection. It is to catch treatable problems earlier, reduce suffering, and protect quality of life. Sometimes the fix is medication. Sometimes it is dental treatment, better skin management, weight support, home modifications, or monitoring changes more closely. Sometimes it is simply recognising that a pet is uncomfortable and doing something about it.

If your older dog or cat is slowing down, losing weight, acting differently, or just not seeming quite right, it is worth taking seriously. “Old age” should be the start of the conversation, not the end of it.
