Senior pet pain signs are rarely dramatic, and that is the difficulty. Animals rarely cry when they are sore, and the changes that matter most look like a pet slowing down.
This is general education rather than a diagnosis. It explains which behaviours are reliable indicators, how to score them at home, and when the finding should become a treatment conversation. Changes in comfort and movement are covered together in our guide to joint health for dogs and cats.
Senior pet pain signs: what owners cannot see
The first signs are usually about willingness rather than appearance. A dog that hesitates before jumping into the car, or a cat that stops using the highest shelf or the top of the cat tree, is showing a functional change rather than a preference.
Posture and movement come next: standing with a hunched back, stiff steps after rest, a change in how a pet sits and lies down, or a reluctance to turn the head in one direction.
Behaviour changes matter just as much. Reduced grooming, irritability when handled, reluctance to be picked up, appetite change, and night-time restlessness all accompany pain in older animals, and they are easy to attribute to age. Clinical guidance recommends structured behavioural observation for assessing pain in animals, precisely because the signs are subtle (measuring pain using structured behavioural observation), and pain management guidance for dogs and cats sets out how assessment and treatment are combined (AAHA pain management guidelines, AAHA/AAFP pain management guidelines).
What do owners get wrong first?
Waiting for an obvious sign is the first mistake.
A pet that is still eating and still greeting you at the door can be uncomfortable, and the threshold that prompts an appointment sometimes arrives late.
The second mistake is interpreting slowing down as inevitable, when a large part of it is treatable and often reflects joint pain or dental disease. The third is attributing irritability to temperament rather than to discomfort, especially in older cats. The fourth is comparing your pet with other pets rather than with their own earlier baseline. Before judging anything, write down what your pet was doing a year ago and what they do now.
Which signs are most reliable?
Signs that describe function are the ones to track.
Time to rise after rest, willingness to jump or climb, distance walked before stopping, and willingness to play are the most informative measures in older animals.
| Observation | What to record | Why it matters |
|---|---|---|
| Rising after rest | Seconds to stand, stiffness duration | Sensitive to joint pain |
| Jumping and stairs | Whether the pet still does it | Early functional change |
| Walking | Distance before slowing | Shows trend over weeks |
| Grooming | Coat condition, area groomed | Reduced grooming in cats |
| Temperament | Handling, resting, interaction | Irritability as a pain sign |
Film your pet walking on the same surface each week, because gait changes are far easier to compare on video than from memory. Where joint pain is suspected, the site’s guide to choosing a joint supplement explains how to evaluate anything added alongside the plan, and body condition matters too, which the site’s guidance on weight reduction covers.
What to change, in what order
Change the environment while the assessment is arranged.
Non-slip runners, a padded bed that is easy to step into, lower litter box sides for cats, and a ramp or steps for the car all reduce discomfort immediately.
Second, keep activity consistent rather than stopping it, since muscle supports joints and complete rest makes stiffness worse. Third, record what you see with dates, so the clinic can distinguish a gradual trend from a recent change, and note anything that coincided with it, such as a new walk route, a change of food, or a house move. Fourth, book the appointment rather than waiting for a bad week, and bring the record with you. For cats, the site’s article on subtle signs of stiffness in cats describes why their pain is especially easy to miss.
What should you measure, and when?
Score the same behaviours weekly. A repeatable record can help describe changes between visits; tracking changes in mobility focuses on that routine.
Use a simple scale for each observation, apply it at the same time of day, and add a short video each week, then compare the trend over a month.
A pet whose scores are drifting in one direction needs an appointment, even if no single day looks bad, because the trend is what indicates that discomfort is increasing rather than fluctuating. If treatment has been started, the same scores become the evidence for whether it is working, which is more useful than a general impression of improvement. Note any change in medication alongside the scores, since that context explains the response.
When does pain need treatment rather than monitoring?
Book when pain affects daily function.
Do not wait for a threshold, since discomfort that limits activity tends to reduce muscle and worsen the original problem over time.
Ask how pain is being assessed, what treatment options fit your pet’s other conditions, and what to monitor at home between appointments. Ask about the review interval and about what would prompt a change in dose, and tell the clinic if your pet becomes difficult to medicate, because adherence is part of the plan. Reviews of treatment for chronic pain in dogs and cats describe how doses are adjusted over time as the condition progresses, which is why the review schedule matters as much as the initial prescription (pain management guidelines for dogs and cats). Owner-level material on age-related conditions is available from the Cornell Riney Canine Health Center.
What to record and review
Keep one page per month.
Record scores for each behaviour, the medication in use, appetite, and any change in the household, then review the page at appointments rather than between them.
The record shows whether the plan is holding and prevents a slow decline from being accepted as inevitable, which is one of the most common ways that treatable discomfort goes untreated in older pets.
Comparing your pet with their own earlier baseline is the most reliable judgement available at home, because age-related decline is gradual and easy to normalise.

FAQ
How can I tell if my senior pet is in pain?
Look at function rather than at obvious signs such as crying. Hesitation before jumping, reluctance to climb stairs, stiffness after rest, a hunched posture, reduced grooming, changes in appetite, and irritability when handled are all common. Structured behavioural observation is the approach clinical guidance recommends, because animals rarely vocalise when they are sore, and owners often notice a change in willingness long before anything obvious appears.
Do animals hide pain?
Dogs and cats often conceal discomfort, and this is more pronounced in cats. Signs frequently appear as behavioural change rather than as an obvious expression of pain, which is why owners so often describe a pet as quieter or slower rather than as painful. That is also why monitoring function over weeks is more useful than waiting for a dramatic sign.
What should I record to help my vet assess pain?
Record specific behaviours with a score: how long it takes to rise after rest, whether your pet jumps or climbs stairs, how they walk, how long they play, and any change in appetite, grooming, or temperament. Add short videos, because gait and posture are easier to assess from footage than from a description. Bring the record to the appointment.
When should pain be treated rather than watched?
Pain should be assessed and treated whenever it affects function, mood, sleep, or appetite, rather than waiting for a specific threshold. There are effective options for older animals, and treatment is often adjusted as the condition progresses. If a pet is reluctant to move, cannot settle at night, or has stopped doing things they used to enjoy, that is a reason to book rather than to monitor.
