A new or worsening change in an older dog or cat—such as eating less, drinking differently, losing weight, slowing down, acting unlike themselves, or developing a wound that will not heal—deserves a veterinary discussion. These signs do not identify one disease, but they should not be dismissed as inevitable aging.
The veterinarian will interpret the pattern in context, beginning with your history and the physical examination and then selecting laboratory tests or imaging that fit the individual pet. Bringing a clear record of what changed and when can make that assessment more useful.

Which changes should you report?
The American Animal Hospital Association (AAHA) identifies several common signs associated with chronic disease in senior pets. A single sign may have many explanations, and a pet can have more than one problem at the same time. Treat the list as a prompt to contact your veterinary team, not as a way to diagnose at home.
| Change you notice | What to document for the veterinarian |
|---|---|
| Malaise or a generally unwell appearance | When it began, whether your pet has good and bad periods, and any accompanying changes |
| Progressive lethargy | Activities your pet has stopped, how long they sleep, and whether energy is declining week to week |
| Behavior changes | New anxiety, irritability, confusion, withdrawal, vocalization, or altered interaction with people and animals |
| Reduced appetite or anorexia | Food offered and eaten, skipped meals, chewing difficulty, vomiting, or trouble swallowing |
| Altered thirst | Whether drinking has increased or decreased and how often water bowls are refilled |
| Weight loss over time | Recent weights, the rate of change, and whether appetite has changed with the weight |
| Mobility changes | Difficulty rising, climbing stairs, jumping, walking, or getting comfortable; note good and bad days |
| Wounds that do not heal | Location, size, discharge, licking or chewing, and how the area has changed |
Also tell the clinic about changes in elimination, grooming, play, vision, hearing, sleep, or social habits. Patterns over time are often more informative than one isolated observation.

Is this “just old age”?
AAHA’s senior-care guidance uses the phrase “old age is not a disease.” Aging changes can occur, but a new or worsening problem still needs an explanation. Assuming that a decline is normal can delay evaluation of a condition that might be manageable, and it can also overlook several issues developing together.
There is no single age at which every dog or cat becomes unhealthy. The guideline definitions differ by species and are intended to identify a life stage for preventive care:
| Animal | AAHA senior-life-stage definition | How to interpret it |
|---|---|---|
| Dog | The final 25% of the estimated lifespan | The calendar age varies with the dog’s expected lifespan; it is not a universal illness threshold. |
| Cat | Older than 10 years in the cited AAHA/AAFP guidance | A 10-year-old cat is classified as senior for care planning, but classification alone does not establish disease. |
In an executive summary published in February 2023, AAHA stated that senior dogs and cats represented 44% of the pet population in the context of its senior-care guidance. That figure does not tell you whether an individual animal is healthy; it underscores why age-appropriate assessment matters.

What happens during an evaluation?
1. A detailed history
The clinician will ask what changed, when it started, and how it has progressed. Questions may cover appetite, thirst, weight, energy, movement, behavior, play, urination and defecation, grooming, vision, hearing, medications, diet, and previous conditions. Your observations help the veterinarian distinguish a short-lived variation from a persistent trend.
2. A physical examination
The examination places the signs in context. The veterinarian may assess body weight and condition, hydration, mouth and teeth, heart and lungs, abdomen, skin and wounds, joints and gait, neurologic responses, eyes, ears, lymph nodes, and blood pressure when indicated. A suspected chronic disease can sometimes be strongly suspected from history and examination, but AAHA recommends appropriate clinicopathologic evaluation rather than relying on age or appearance alone.
3. A minimum laboratory database when chronic disease is suspected
AAHA’s 2023 Senior Care Guidelines describe a detailed blood profile that includes a thyroid panel and a urinalysis as the minimum database for a senior pet with suspected chronic disease. “Minimum” does not mean every pet receives an identical panel at every visit; the veterinarian chooses tests that answer the questions raised by the examination and history.

4. Additional tests when the findings call for them
Imaging and targeted diagnostics may be added according to the body system involved and the initial results. Examples can include further blood tests, radiographs, ultrasound, or other procedures, but the AAHA body-system table is expressly not an exhaustive or mandatory checklist. The clinician should explain what each proposed test is intended to clarify, what preparation or restraint it requires, and how the result could change the plan.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Clear out junk files and repair common Windows errors3Fix the driver behind crashes, sound loss and screen glitches5. Ongoing senior screening
AAHA’s client guidance says routine senior visits may include a complete blood count, chemistry testing, urinalysis, thyroid testing, and blood pressure, with the selection tailored to the animal. It recommends veterinary examinations every six months for senior pets, including those that appear healthy. A routine interval is preventive guidance, not a reason to wait when a pet is newly or progressively unwell; call the treating clinic so it can advise on timing.
Why more than one condition can matter
Senior pets commonly present with overlapping signs, and concurrent medical issues can make both diagnosis and treatment decisions more complex. Reduced appetite, low energy, weight change, or altered behavior may arise from different body systems, and one problem can mask another. The veterinarian therefore interprets clinical presentation, laboratory values, imaging, histopathology when obtained, and relevant epidemiology together rather than matching one symptom to one disease.

- How to Use – Put the thermometer close to pet's ear and remove the hair to make sure the measurement is correct. Non-contact infrared is easy to measure pet's ear temperature.
- Accuracy – The thermometer has been tested again and again to be clinically accurate with every measurement you take. (Allow ±0.36℉)
- Result in 2 Second – Result in 2 second without contacting to pets. Less invasive feeling for pet even needs to measure three times to make sure accuracy measurement compare with anal temperature monitor.
- Animal Friendly – Special design for dogs, cats, horse, rabbit and other animals.
- Ergonomic Design - The thermometer is easy to hold, small-diameter probe enables animal temperature collection of any size animal.
If the case involves complicated comorbidities or requires specialized testing, referral to an appropriate veterinary specialist may be recommended. A referral is a way to add expertise for a difficult case, not evidence that a diagnosis is hopeless.

Include the date or an approximate week and whether the change is stable, intermittent, or worsening.
- Track food and water. Record appetite, meal amounts when practical, unusual begging or refusal, vomiting, and how often water is replenished.
- Record weight and body changes. Bring recent clinic weights or use the same home scale consistently if your pet tolerates it. Note muscle loss, a changing waistline, or a coat that looks different.
- Describe movement. Note trouble rising, stairs, jumping, slippery floors, walks, or getting into a litter box. A short video of your pet moving at home can show a pattern that does not appear in the clinic.
- List behavior and daily-function changes. Include sleep, interaction, play, grooming, accidents, vocalization, confusion, vision, and hearing.
- Bring complete medication and diet information. List prescription drugs, over-the-counter products, supplements, treats, feeding schedule, and any recent changes. Do not stop or start a product solely because of a symptom.
- Bring questions and practical constraints. Tell the veterinarian about concerns regarding cost, travel, restraint, anesthesia, or your pet’s stress. These factors can be part of a responsible plan.
AAHA’s home-monitoring materials encourage regular observation and communication with the veterinary team. A paper notebook or digital note can organize observations, but it cannot detect disease, determine urgency, or replace an examination.

Discussing tests, treatment, and quality of life
Diagnostic decisions involve both potential value and burden. Ask what a test is looking for, how reliable the result is likely to be in this situation, what preparation it requires, and what decisions would follow from a positive, negative, or inconclusive result. The veterinarian can then match the plan to the pet’s findings and your family’s circumstances.
Some caregivers decline a test or treatment because of cost, concern about procedures, age, transport difficulties, or fear that the process will distress the animal. AAHA recommends discussing symptomatic treatment and its potential quality-of-life benefit when diagnostics or treatment are declined. Depending on the condition, that conversation may include comfort-focused care or palliative care. It should be a shared decision with the veterinarian, not a reason to self-treat or assume testing is futile.
Useful questions include:
- What problems are most important to rule in or rule out first?
- Which test would change what we do, and which result would not change the plan?
- What are the immediate burdens, risks, and costs of each option?
- What signs would show that comfort or daily function is improving?
- When should we recheck, and whom should we call if the condition changes?
When should you call the clinic?
Contact the veterinary clinic when a senior pet develops a persistent, worsening, or clearly unusual change, even if the next routine examination is months away. If a change is sudden or severe, describe exactly what you are seeing and when it began so the clinic can advise how quickly your pet should be assessed. Do not wait for a symptom list to become extensive before reporting a meaningful decline.
After the visit, follow the agreed monitoring plan and report new information. A response to supportive care, a new symptom, or a change in eating, drinking, movement, or behavior can alter the veterinarian’s next diagnostic or treatment decision.
The practical takeaway
Senior status is a reason for attentive monitoring, not a diagnosis. Report changes in appetite, thirst, weight, energy, behavior, mobility, or wound healing; bring a timeline, medication and diet details, and useful home videos; and let the veterinarian select tests according to the individual findings. Regular six-month examinations support preventive care, while a new or progressive problem merits contact sooner.
