Pets get older sooner than many owners think
Senior in pet years isn't quite what owners often assume. The general UK rule of thumb:
- Large and giant dogs (Great Dane, Newfoundland, Mastiff) are typically considered senior at 6–7 years.
- Medium dogs (Labrador, Spaniel, mid-sized terriers) are generally senior at 7–8 years.
- Small dogs (Yorkie, Cavalier, Chihuahua) are typically senior at 9–10 years.
- Cats are generally considered senior at 10 years, geriatric at 15+.
The practical implication: many UK pets enter their senior phase around the time owners are still mentally treating them as middle-aged. Catching age-related changes early is often the difference between treatable conditions and missed ones.
Twice-yearly checks become standard
From senior age onwards, UK veterinary recommendation generally shifts from annual wellness checks to twice-yearly. Six months is roughly equivalent to three or four human years for an older pet — long enough for serious conditions to develop. Your practice will usually offer a senior wellness panel (bloods, urine, blood pressure) once or twice a year as part of the visit.
What to watch for at home
Many age-related conditions develop gradually. The owner who knows their pet best is often the one who catches the change first.
Senior change → what it could be
| What you're noticing | Specific signs | What it could be |
|---|---|---|
| Mobility | Slower to get up; reluctant on stairs; stiffness after rest that improves with movement; difficulty getting into the car. | Osteoarthritis (common in senior dogs and cats). Often highly treatable — worth pushing back on "they're just old". |
| Drinking and urination | Drinking noticeably more or less; urinating more often or in larger volumes; accidents indoors; changes in toileting posture. | Kidney disease, diabetes, Cushing's, urinary tract infection. Diagnosable, often manageable. |
| Weight | Sudden changes in either direction. Loss of muscle along the spine. Pot belly that wasn't there before. | Many conditions — thyroid, diabetes, cardiac, GI disease, even cancer. Worth investigating any unexplained change. |
| Eating and toileting | Reduced appetite; difficulty eating dry food; vomiting; changes in stool consistency or frequency. | Dental disease (very common, often hidden), GI issues, kidney disease. |
| Behaviour | Confusion at night; pacing; staring at walls; loss of housetraining; sleeping more or less; reduced response to known cues. | Cognitive dysfunction (canine and feline), pain, sensory loss. Both lifestyle and medical interventions exist. |
| Lumps and skin | Any new lump or bump; changes in existing lumps; sores that don't heal. | Range from benign to serious. Worth flagging at the next visit; don't delay if changing. |
| Vision and hearing | Bumping into things; startling when approached; reduced response to name. | Cataracts (in dogs particularly); age-related changes; sometimes early sign of dementia. |
"They're just getting old" can hide treatable disease
Many genuinely treatable senior conditions — osteoarthritis, dental pain, hyperthyroidism, kidney disease in cats — are sometimes dismissed as normal ageing. The reduced quality of life is often treatable; the decline isn't always inevitable. If your vet doesn't take concerns about an older pet seriously, a second opinion can be worth seeking.
What changes day to day
A senior pet often does fine with small adjustments rather than wholesale change. Practical things that tend to help:
Soft, supportive bedding
Memory foam or orthopaedic beds can reduce joint pain in arthritic pets, which includes many senior dogs and many senior cats. Multiple beds around the house mean less moving around to find a comfortable spot. For cats, low-sided beds or boxes — climbing in often becomes harder than you'd expect.
Modify the environment
Ramps onto sofas and into the car. Non-slip rugs on slippery floors (older dogs often lose confidence on laminate). Litter trays with low sides for cats. Raised feeding bowls for tall dogs with neck arthritis. None of this is dramatic but it removes daily friction.
Adjust exercise, don't eliminate it
Senior pets generally still need movement — inactivity tends to make arthritis worse, not better. Shorter, more frequent walks. Swimming for dogs with joint issues. Mental enrichment (sniff walks, food puzzles) for dogs whose physical exercise has reduced. For cats, low-impact play that doesn't require leaping.
Diet review
Senior pets often benefit from a diet review around age 7 (dogs) or 10 (cats). Calorie reduction is common; protein levels matter for cats with kidney concerns; joint-supportive ingredients (omega-3, glucosamine) have a reasonable evidence base for arthritis. Discuss with your vet — don't randomly switch to a 'senior' branded food without thinking.
Dental care matters more than ever
Untreated dental disease can cause daily pain in many senior pets, and bacteria from infected gums can affect kidneys, liver, and heart over time. A dental check is generally part of the twice-yearly senior visit — if your vet recommends a scale and polish under anaesthesia, the risk-benefit is usually firmly in favour even for older pets.
The video evidence
“If you're noticing something at home that seems intermittent — occasional limping, the way the cat lands stiffly, a strange head tilt that comes and goes — record a short video on your phone next time it happens. Show it to your vet. It's often far more useful than describing the symptom in a calm consulting room where the pet looks completely fine.”

Common questions
Add the next visit before you leave the current one
One of the most useful habits with a senior pet: book the next six-month check before you leave today's appointment. The practice will remind you, you won't forget, and small problems get caught small.
