By Dr Duncan Houston
Your dog might still wag their tail, accept a treat and greet you at the door while something is wrong. The first clue may be smaller: a shorter walk, a restless night or a water bowl that needs filling more often.
These changes are easy to miss when life is busy. They can be even harder to recognise when someone else is looking after your dog.
Tracking everyday health and useful vital signs gives those small changes a history. That can help you recognise a problem, explain it to your vet and make sure your dog receives consistent care while you are away.
Quick Answer
Tracking your dog’s health helps you recognise changes in breathing, appetite, drinking, movement, sleep and behaviour that might otherwise go unnoticed. Knowing your dog’s usual patterns is particularly useful when a sitter or family member takes over their care. Records and suitable monitoring devices can support earlier veterinary assessment, but cannot diagnose every illness or guarantee that your dog is well. Breathing difficulty, collapse or other emergency signs need immediate veterinary attention, even when a tracker shows normal readings.
Why do owners miss the early signs?
Dogs cannot explain that their joints hurt, that they feel nauseous or that breathing has become harder.
People often describe animals as “hiding” illness. In practical terms, dogs may show discomfort through subtle changes in posture, movement and behaviour instead of obvious crying or limping.
AAHA’s pain guidelines highlight that owners may recognise dramatic signs of acute pain while overlooking gradual changes associated with chronic pain.
A dog might start getting up more slowly, avoid the stairs or stop bringing you their favourite toy. Because it happens gradually, the new behaviour can become the household’s new normal.
Slowing down should not automatically be dismissed as ageing. Chronic pain can be mistaken for normal age-related change, and videos of movement at home can help the veterinary team assess it.
Missing a subtle sign does not make someone a bad owner. A simple record helps reduce how much everyone has to rely on memory.
What should you track?
Veterinary vital signs include measurements such as heart rate, breathing rate and body temperature. Daily health tracking also includes observations about how your dog eats, moves, rests and interacts.
You do not need to turn your lounge room into an intensive care unit. Start with information you can collect comfortably and consistently.
| What to track | Useful details to record |
|---|---|
| Appetite | How much of the usual meal was eaten, enthusiasm for food and difficulty chewing |
| Drinking and urination | Changes in water use, toilet frequency, accidents or straining |
| Breathing | Sleeping breathing rate when appropriate, effort, new coughing or unusual noise |
| Movement and activity | Walk tolerance, stiffness, limping, reluctance to jump and recovery afterwards |
| Sleep and behaviour | Restlessness, pacing, withdrawal, irritability or difficulty settling |
| Weight and body condition | Measurements on the same scales and changes in muscle or body shape |
| Vomiting and stools | Frequency, appearance and whether your dog otherwise seems well |
| Medication | Dose actually given, time, missed doses and possible adverse effects |
Record changes in context. A hot day, a different walking routine, a new medicine or boarding stay may help explain what you are seeing.
For a dog with an existing medical condition, ask your vet which measurements matter most and how often to record them.
Your dog’s normal pattern matters
A healthy young working dog and a senior dog with arthritis will have very different activity patterns. Comparing their step counts tells you little about either dog’s health.
Compare your dog with their own usual pattern under similar conditions.
For example, a dog that normally enjoys a comfortable 30-minute walk but repeatedly wants to turn home after 10 minutes has changed. That deserves attention even if they are still walking every day.
Home observations also add context to a clinic visit. Research has shown that the veterinary hospital environment can affect dogs’ pulse, temperature and other measurements. Calm home observations can therefore complement the examination.
A persistent change from normal can matter before your dog looks obviously unwell. However, do not wait to establish a baseline if something already seems wrong.
How to check your dog’s sleeping breathing rate
Breathing rate is one useful measurement owners can learn without handling their dog. It is particularly valuable for some dogs with heart disease.
-
Wait until your dog is sleeping comfortably in a cool environment.
-
Avoid counting during panting, active dreaming or immediately after exercise.
-
Count one rise and fall of the chest as one breath.
-
Count for 30 seconds and multiply by two.
-
Record the result with the time and any other changes.
University veterinary guidance supports this method and recommends watching for a persistent upward trend.
Many relaxed dogs breathe around 15 to 30 times per minute. Repeated sleeping readings above roughly 30 to 35, or a clear sustained increase from your dog’s usual rate, warrant a prompt call to your vet. Follow any specific threshold your vet has set for your dog.
Breathing effort matters as much as the number. A dog using their belly to breathe, stretching their neck to get air or struggling to settle needs urgent assessment. Do not keep counting while a dog struggles to breathe.
Heart rate and temperature need careful interpretation too. Ask your vet whether home measurements would be useful and how to obtain them safely. Do not force handling or assume a wearable reading is interchangeable with a clinical measurement.
What could a change mean?
Tracking reveals a change; your vet works out the cause.
A drop in activity may reflect a quieter routine, hot weather, pain or illness. Restless sleep might accompany anxiety, discomfort or needing to urinate more often. The combination of signs helps determine which explanations need investigating.
For example, increased thirst and urination together with weight loss can occur with diabetes. Diagnosis requires veterinary assessment and testing, not simply a water-bowl log.
Likewise, frequent small wees, straining or new accidents can indicate urinary disease. Recording whether your dog passes large amounts or repeatedly tries to pass small amounts gives your vet useful information.
Dates, videos and measurements help answer practical questions: When did it start? Is it worsening? Did anything change beforehand?
How worried should you be?
| What you notice | What to do |
|---|---|
| A slightly quieter day with normal eating, comfortable breathing and normal toileting | Check for an obvious routine change and observe closely. Contact your vet if it persists, repeats or worsens |
| Repeated stiffness, reduced walk tolerance, disturbed sleep or unexplained weight change | Arrange a veterinary appointment rather than accepting it as the new normal |
| A marked appetite change, increased thirst, new urinary signs or a sustained rise in sleeping breathing rate | Contact your vet promptly, generally the same day, for individual advice |
| Breathing difficulty, collapse, severe weakness or other emergency signs | Seek emergency veterinary care immediately |
Puppies, frail seniors, dogs recovering from surgery and dogs with chronic disease may need earlier assessment. Follow their existing care plan.
Can you trust someone else to notice when you are away?
A good sitter may be caring, reliable and experienced while still being unfamiliar with your dog’s normal habits.
They might see a dog sleeping quietly and assume everything is fine. You might know that this particular dog normally rushes to the kitchen at breakfast and rarely leaves food behind.
Trust works best when the person caring for your dog has clear information and a plan.
Before leaving, explain normal appetite, activity, toileting and behaviour, along with medical conditions and medication instructions. AAHA recommends sharing these details so carers can maintain routines and recognise concerns.
Choose someone who can meet your dog’s needs. For a dog needing injections, complex medication or close observation, confirm that the carer can perform the required tasks safely before you go.
Give your carer a practical handover
Include:
-
What is normal: Meal amounts, usual walks, sleep habits and toilet routine.
-
What needs recording: Food eaten, medication given and any condition-specific measurements.
-
What needs a phone call: Clear changes and your vet’s individual thresholds.
-
Where to get help: Your regular clinic, an emergency hospital and a nearby backup contact.
-
How to act if you are unreachable: Treatment authorisation, transport and payment arrangements.
Veterinary senior-care guidelines specifically recommend arranging decision-making authority and emergency payment plans when an owner will be unavailable.
Ask for useful updates. “Ate half of breakfast, declined the usual walk and has been pacing” gives you far more information than “Seems fine.”
For medication, everyone should use the same record and mark doses after administration. A reminder shows that a dose is due; it does not confirm that your dog received it.
How can trackers and cameras help?
Depending on the device, a wearable may record activity, estimate rest patterns or measure selected physiological signals. These records can show changes between the moments when someone is directly watching your dog.
AAHA and AVMA guidance recognises the potential of remote monitoring to identify concerning trends and recommends agreeing with your vet how the information will be used.
However, devices differ. Check what the exact model measures, how it has been validated and when readings may be unavailable or unreliable. Research on one veterinary monitoring harness found that it could follow some trends, but individual readings needed confirmation before clinical decisions. That finding cannot establish the accuracy of every other device.
A pet camera may help you notice pacing, repeated attempts to settle or unusual behaviour. Agree on its use with your carer and make sure someone nearby can respond if needed.
Monitoring only helps when someone checks the information and acts on a concern.
Before travelling, test charging, connectivity, notifications and access. Decide who receives alerts and who physically checks the dog. Cameras and wearables supplement attentive care; neither provides food, gives medication or transports an unwell dog to the vet.
When is this an emergency?
Seek immediate veterinary care for:
-
Difficult or laboured breathing.
-
Collapse, unresponsiveness or profound weakness.
-
A swollen abdomen with repeated unsuccessful attempts to vomit.
-
Repeated straining with little or no urine.
-
Prolonged or repeated seizures.
-
Suspected poisoning or medication overdose.
-
Significant bleeding or severe pain.
These are reasons to seek urgent help rather than continue routine monitoring. Cornell’s emergency guidance includes breathing difficulty, collapse, non-productive retching and a painful or distended abdomen among emergency presentations.
If you are away, the carer should contact the emergency clinic and begin the agreed response. They should not wait for you to finish a flight or wake up in another time zone.
A normal app score must never override a visibly unwell dog.
Build a simple tracking routine
Start while your dog is well:
-
Choose one place for records. A notebook, shared document or suitable health app can work.
-
Make a brief daily check. Notice appetite, drinking, toileting, movement and comfort.
-
Add targeted measurements. Follow your vet’s advice for breathing rate, weight or disease-specific monitoring.
-
Record changes precisely. Include when they happened and a short video when safe.
-
Share a concise summary with your vet. Explain the change, its duration and associated signs.
-
Agree on the next action. Know when to call again and which signs need immediate care.
Avoid changing medication, restricting water or pushing exercise to “test” an unwell dog without veterinary advice.
Common mistakes to avoid
-
Waiting for crying or collapse. Early changes can be much quieter.
-
Dismissing everything as ageing or missing you. Behavioural explanations should not automatically exclude illness.
-
Trusting one normal reading. One measurement cannot rule out disease.
-
Collecting information without reviewing it. Records need an action plan.
-
Assuming the sitter knows your dog’s habits. Explain the details that matter.
-
Replacing check-ups with a tracker. Physical examinations and appropriate testing remain essential.
Keep monitoring alongside healthy weight management, suitable exercise, enrichment, positive new experiences, stress reduction and preventive veterinary care. Tracking can help you judge whether those routines continue to suit your dog.
Frequently asked questions
Should I track my dog’s health even if they seem healthy?
Yes. Basic observations made while your dog is well help establish their usual habits. You can then recognise changes more clearly.
Do I need an expensive health tracker?
No. Consistent observations, a simple log and occasional useful videos can provide valuable information. A suitable device may add detail or convenience.
Can a tracker detect every illness?
No. Capabilities and accuracy vary, and many conditions require examination or testing. Seek veterinary advice when your dog seems unwell, even without an alert.
How often should my sitter send updates?
Agree on scheduled updates that suit your dog’s needs, commonly daily for a healthy adult. Concerning changes should be reported immediately rather than saved for the next update. Dogs with medical conditions need a specific plan from their treating vet.
Your dog’s everyday habits contain useful clues about their health. Knowing those habits, recording meaningful changes and sharing them with the people providing care gives everyone a better chance of recognising when help is needed.
