Changes in movement, sleep or handling tolerance deserve attention. They may have several causes; an examination can identify support or treatment, but not every condition is treatable or reversible.
I am not a vet. This is what I read while watching a friend’s dog get old and wondering how much of it we were supposed to just accept.
Twice a year, not once
The single clearest instruction in the veterinary guidance is about frequency. The AVMA states that “Senior pets need to see a veterinarian twice a year or more so signs of illness or other problems can be found and treated early.”
The reason is arithmetic. A dog ages considerably in twelve months, so an annual visit on an older dog is a long gap for something to develop unnoticed. Senior exams are also more thorough than a young dog’s check-up, and often include bloodwork and dental assessment.
There is no single age at which a dog becomes senior. Large breeds get there years earlier than small ones, so this is a question for your vet about your dog rather than a birthday.
Slowing down is a symptom, not a stage
This is the one owners most often accept without questioning. The AVMA is clear that reduced activity is commonly caused by arthritis, and lists the signs to watch for: favoring a leg, stiffness when walking, difficulty standing or sitting, increased sleeping, resistance to being touched, less play, and sometimes unexpected aggression toward people or animals.
Snapping during touch can involve pain, fear or another cause. Stop the interaction, give space and arrange veterinary assessment rather than diagnosing personality or pain from one response.
Arthritis is manageable. There are things your vet can do, and the sooner it is identified the more of your dog’s comfortable years you keep.
Ageing, or something to treat?
Everything in this table is worth raising at an appointment. None of it is simply old age.
| What you notice | Possible concern | Next step |
|---|---|---|
| Stiffness, reduced mobility or trouble rising | Pain or another health change | Contact your vet for assessment. |
| New irritability with touch | Pain, fear or another cause | Stop handling and seek veterinary advice. |
| Unexpected weight change | Nutrition or a medical problem | Contact your vet; record intake and weight. |
| New confusion, night pacing or accidents | Several medical or behavioral causes | Ask promptly; sudden severe signs need urgent assessment. |
| Marked thirst or urinary change | A medical problem | Contact your vet promptly; inability to urinate is an emergency. |

Weight matters more now than it ever did
The AVMA is blunt about the stakes: “Obesity in senior pets is linked to an increased risk of arthritis, difficulty breathing, insulin resistance or diabetes, heart disease, high blood pressure, skin problems, cancer, and other conditions.”
The awkward part is that an older dog moves less, so the weight goes on more easily at exactly the point it costs the most. Every extra kilo is carried by joints that are already sore, which makes movement less appealing, which puts on more weight.
Track weight as well as body and muscle condition with your vet. Agree portions and recheck timing for your dog; do not wait a month to report an unexplained change.
Behavior change is often the first sign
The AVMA notes that behavior changes can be the first indicator of aging, and that they may come from discomfort, from failing sight or hearing, or from cognitive dysfunction.
The cognitive picture includes sound sensitivity, excessive vocalisation, increased aggression or protectiveness, anxiety, disorientation, wandering, accidents indoors, disrupted sleep, less play, repetitive behavior, reduced response to commands, and memory problems.
A dog who stops responding when called is usually assumed to be stubborn. He may not be able to hear you. A dog who barks at nothing at three in the morning is not being difficult. Both are reasons to book rather than to train harder. Our guide to fear and aggression in dogs covers why pain gets misread as temperament.
Most of what helps an older dog costs very little.
Secure non-slip flooring can help movement. Ask your vet about ramps, bowl height and other adaptations for the individual dog rather than expecting improvement in a day.
Give him a supportive bed somewhere warm and out of the through-traffic, and keep the layout predictable if his sight is going. Keep walks going but make them shorter and more frequent rather than one long one.
Adjusting for an older dog
- Move to twice-yearly vet visits, as the AVMA recommends
- Put rugs or runners on the routes he walks most
- Track weight, body condition and muscle condition with your vet
- Split one long walk into two or three shorter ones
- Ask your vet whether a different bowl height is appropriate
- Keep furniture where it is, especially if sight is fading
- Write down anything you notice, with the date, and take it to appointments
Keep him moving, gently
Movement and rest should follow the dog’s pain and health plan. Do not exercise through pain or assume all stiffness improves with activity; ask your vet about comfortable movement and any restrictions.
Short frequent walks on soft ground beat one long walk on pavement. Swimming suits some dogs. Sniffing counts as real work, so let him take his time rather than towing him along, and use scatter feeding indoors on days the weather is against you.
Watch for the pattern where he is fine during a walk and stiff that evening. That usually means the walk was too long, and the honest fix is shorter and more often. Our guide to exercise routines for dogs covers matching activity to the dog in front of you.
Book twice-yearly check-ups as standard. Call sooner if your dog:
- Is avoiding stairs, jumps, or getting into the car
- Is stiff after rest, favors a leg, or resists being touched
- Is drinking noticeably more, or having accidents indoors
- Is disoriented, pacing at night, or vocalising at nothing
- Has lost or gained weight without you changing anything
- Has bad breath, is dropping food, or chewing on one side
Take a written list of changes with dates. Owners routinely forget half of it in the room, and the pattern over months is exactly what your vet needs. Ask about pain management specifically, because “he is just old” is not a diagnosis.
What good looks like at this stage
Not a dog who behaves like a three-year-old. A dog who is comfortable, interested in his day, eating well, and doing the things he still enjoys without paying for them that night.
Keep a short monthly note: what he can still do, what he has stopped doing, appetite, and sleep. It takes a minute and it turns a vague sense that he is slowing into something you and your vet can actually act on.
Our guides to a home care routine and planning ahead for your dog’s final days cover either side of this period.
Book the check-up tonight if it has been more than six months. That one action does more than everything else on this page.

Questions people ask
How often should my older dog see the vet?
Plan on two vet visits a year for an older dog, or more if your vet advises it. Dogs do not reach their senior years at one set age, since breed and size matter. Ask your vet when this schedule should begin for your dog. Between visits, write down changes in movement, appetite, sleep, bathroom habits, hearing, and sight.
Is my old dog slowing down because of age or pain?
A slower pace can come with age, but stiffness, limping, trouble rising, stair avoidance, less interest in play, or anger during touch can point to pain or another health problem. Note when the change happens and whether it follows rest or exercise. Call your vet for an exam, since a behavior or movement change needs a medical check before you write it off as age.
How can I make my home easier for an older dog?
Put rugs or runners on slick floors, offer a supportive bed in a warm spot, and use a ramp if getting into the car has become hard. Keep furniture in familiar places if sight has faded. Choose shorter walks and allow time to sniff. Watch for slips, stiffness after activity, or reluctance to bend, jump, or use stairs, and call your vet about those changes.
How can I tell if my older dog is gaining too much weight?
Use your hands to check body shape each week. You should be able to feel the ribs under a thin layer, see a waist from above, and find a tuck behind the ribs. Older dogs may gain weight as activity drops, so ask your vet about food amounts and suitable exercise. Call the clinic if weight rises or falls without a change you can explain.
Why is my old dog pacing at night?
Night pacing can involve pain, sensory changes, cognitive change or another problem. Contact your vet promptly about a new change; sudden severe confusion, collapse or other acute illness needs urgent advice. Keep paths clear and record observations without delaying care.
