Checking your pet's weight and vital signs at home gives you a baseline for noticing change, not a way to diagnose disease. Temperature, pulse and respiration are the three main vital signs in animals, often shortened to TPR. Weight and body condition add another useful trend because gradual loss or gain can appear before a pet's illness is obvious.
I learned the value of a baseline with my elderly cat, Pilchard. Because I cared for her at home and spared her a stressful car trip, I did not have a reliable recent weight to compare when kidney disease became a concern. A simple monthly record would not have named the disease, but it could have shown the change sooner.

What Counts as Your Pet's Vital Signs
What are the three main vital signs in animals? They are temperature, pulse and respiration, commonly shortened to TPR. Temperature reflects heat regulation, pulse shows how fast the heart is beating, and respiration describes the breathing rate. Together, these three readings provide a quick snapshot of basic body function. Weight and body condition are not part of TPR, but tracking them alongside TPR makes gradual change easier to recognize.
- 1TPR stands for temperature, pulse and respiration.
- 2Measure a calm or sleeping pet whenever possible, use the same method each time and record the date, time and circumstances.
- 3Add weight and body condition score to the log, because trends often matter more than one reading.
Home checks do not replace an examination. Pain, excitement, panting, purring, a warm room and recent activity can all shift the numbers. If your pet looks distressed, collapses, has blue or very pale gums, struggles to breathe or cannot stand, seek emergency veterinary care instead of trying to complete the checklist.
Normal Vital Signs for Dogs and Cats: Ranges Chart
This combined animal vital signs chart uses published veterinary reference ranges. Normal dog vital signs and normal cat vital signs overlap, but dog normal vital signs vary more by body size, especially for pulse. The Merck Veterinary Manual temperature table lists 99.5-102.5 degrees Fahrenheit for dogs and 100.5-102.5 degrees for cats. Merck's small-animal triage parameters give normal resting heart-rate ranges of 60-120 beats per minute for large dogs, 70-120 for small dogs and 150-220 for cats.

This normal-range chart for dogs and cats covers temperature, heart rate and respiratory rate. Every number was checked against a primary veterinary source: the Merck Veterinary Manual for temperature and triage heart-rate ranges, and Cornell University College of Veterinary Medicine for the shared resting respiratory range and the point at which owners should contact a veterinarian.
| Vital sign | Dogs | Cats |
|---|---|---|
| Rectal temperature | 99.5-102.5 degrees F | 100.5-102.5 degrees F |
| Resting heart rate | 60-120 beats per minute for large dogs; 70-120 for small dogs | 150-220 beats per minute |
| Resting respiratory rate | Usually 15-30 breaths per minute | Usually 15-30 breaths per minute |
For breathing, Cornell University College of Veterinary Medicine gives a normal resting respiratory rate of 15-30 breaths per minute for both dogs and cats and advises contacting a veterinarian when a resting rate is above 35. Merck's normal dog respiratory rate is a slightly wider 18-34 range, which is a reminder that reference intervals vary by source and patient. Your veterinarian's range for your individual pet takes priority.
The vital signs of a dog or cat should be measured only when the pet is calm and resting. This dog vital signs chart and the normal vital signs for cats and dogs in its companion column do not apply during exercise, panting or a stressful event. Puppies, kittens, small dogs, stressed cats and animals in pain may have faster heart rates, so record what your healthy pet does under the same quiet conditions and use the chart as context rather than treating its edges as a diagnosis.
Step-by-Step: Checking Your Pet's Vital Signs at Home
How can I check my dog's vital signs? Choose a calm time, gather a phone timer and your log, then measure in the same order each time. The process works for cats too, but do not force any step on a frightened or struggling animal.
- Let your pet rest quietly for at least several minutes. Note recent exercise, stress, medication, food and room temperature.
- Watch the chest for a full minute and count each rise and fall as one breath.
- Find the heartbeat on the left chest or the femoral pulse high inside a rear leg. Count for 15 seconds and multiply by 4.
- Take a temperature only if your pet tolerates safe handling and you know the rectal technique.
- Weigh your pet under the same conditions and assess body condition by looking and feeling.
- Record every result, even when it is normal, so later readings have a true baseline.
Digital tools can help organize observations, but they measure different things. Maven Pet can be used as part of a broader health-tracking routine; it does not replace hands-on TPR measurements or veterinary interpretation.
Do not measure everything every day in a healthy pet unless your veterinarian asks you to. A monthly check is a practical baseline cadence for many adults. Pets with heart disease, kidney disease, diabetes, a weight plan or another diagnosed condition need the monitoring schedule their veterinarian sets.

How to Check Your Pet's Heart Rate
To check a heartbeat without equipment, place a flat hand on the left side of the chest just behind the elbow. On many dogs and cats you will feel a steady bump under your palm or fingertips. The heart-rate demonstration image below shows the correct hand on the chest at the left side, with the pet relaxed rather than standing on an exam table.
You can also feel the femoral pulse. Slide two fingertips high on the inner thigh where the rear leg meets the body, using fingertips rather than a thumb because your thumb has its own pulse. Count beats for 15 seconds and multiply by 4. Repeat once if the number seems surprising, and write down whether the rhythm felt regular, weak, unusually strong or uneven.
If you are learning how to check a dog's heart rate at home, start with a hand on the chest or the femoral pulse before adding equipment. To learn how to check a dog's heart rate with a stethoscope, place the chest piece on the left chest behind the elbow and listen in a quiet room. A home stethoscope can make beats easier to hear, but it cannot tell you why a rhythm is abnormal.
How to Check Your Pet's Breathing Rate
Wait until your pet is asleep or resting calmly. Cats should not be purring, and dogs should not be panting. Watch one point on the chest or abdomen, count one complete rise and fall as one breath and count for 60 seconds. A 30-second count multiplied by 2 also works, but a full minute reduces rounding error. This breathing check summary hands the species-specific counting depth to the two respiratory-rate sibling guides below, where dog and cat instructions are treated separately.
Breathing effort matters as much as the number. The chest should move smoothly without the belly heaving, the nostrils flaring or the neck stretching forward.
Use the species-specific handoff that matches your pet:
- Dogs: Count only when the dog is resting and not panting, then use Petful's guide to the normal respiratory rate for dogs for dog-specific counting technique and interpretation.
- Cats: Count when the cat is asleep or quietly resting and not purring, then use the normal respiratory rate for cats guide for feline technique and warning signs.

How to Take Your Pet's Temperature
A digital rectal thermometer gives the most dependable home reading, but it requires calm restraint and is easiest with two people. Prepare everything before handling the pet so the check stays brief. The step-by-step temperature check below uses a digital rectal thermometer, water-based lubricant and gentle restraint. Stop whenever safe handling is no longer possible, and never force the device or risk a bite just to obtain a number.
- Label a digital thermometer for pet use, switch it on and apply a water-based lubricant to the tip.
- Ask a helper to support the standing pet calmly and prevent sudden backing, twisting or sitting.
- Lift the tail gently and insert only the lubricated tip far enough for the thermometer to read, without forcing or angling it.
- Hold the thermometer steady until it signals that the reading is complete.
- Remove it gently, record the temperature and clean the device according to the manufacturer's directions.
Stop if your pet becomes frightened, sits down, twists sharply or tries to bite. Do not risk injury to get a number. Ear and forehead thermometers can be less consistent in pets unless they are designed and used correctly, so tell your veterinarian which method produced the reading.
Weighing Your Pet and Body Condition Score
For a dog or cat you can safely lift, weigh yourself, weigh yourself holding the pet and subtract the first number. Use the same scale and similar conditions each time. A small pet scale can improve consistency for cats, toy dogs and young animals, especially when a small change matters.

For a small-pet scale reading:
- Put the scale on a hard, level floor and zero it before the pet steps on.
- If you use a thin nonslip towel, place it first and use the tare function so its weight is excluded.
- Guide the pet fully onto the platform without pressing down or holding the body.
- Wait for a stable number, then repeat once if the pet shifted during the reading.
- Record the result under the same conditions each time, such as before breakfast on the first weekend of the month.
This weight-tracking plan pairs small-pet scale technique with body condition scoring and a reusable monthly vital signs log cadence. Using the same scale, time of day and resting conditions makes each entry easier to compare, while the body condition score adds context that weight alone cannot provide. Keep the monthly record simple enough that you will actually maintain it between veterinary visits.
The number on the scale does not tell the whole story. A body condition score estimates fat by combining a top view, side view and touch. The AAHA nutrition guidelines recommend a standardized 9-point scale and include body weight, body condition score and muscle condition score in a nutritional assessment. At an ideal score near 4-5 out of 9, the ribs are easy to feel with a light covering, a waist is visible from above and an abdominal tuck is present from the side.
For a healthy adult, create one reusable vitals log row each month. Use the same calendar cue and resting conditions so the entries are comparable. Follow a veterinarian's daily or weekly cadence for a diagnosed condition, and do not force a temperature check merely to fill every field.
What to Record Each Month
- Date and time
- Weight and body condition score
- Resting heart rate in beats per minute
- Resting respiratory rate in breaths per minute
- Temperature, when safely measured
- Appetite, energy, medication changes and anything unusual
Urine-focused products such as the CheckUp Pet Wellness Urinalysis Testing Kit and PrettyLitter Health Monitoring Cat Litter concern changes outside TPR. Keep those results separate in the log, follow their directions and ask your veterinarian to interpret anything abnormal.
Pet insurance does not change when a pet needs care, but planning for unexpected costs can make decisions less stressful. If you use Lemonade pet insurance or another provider, learn the waiting periods, exclusions and claim requirements before an emergency. Never delay a veterinary visit while checking coverage.
When to Call the Vet
Call your veterinarian when a resting result is repeatedly outside your pet's established range, when a trend moves steadily in one direction or when the number and the pet's behavior do not match. Recheck once only if your pet is calm and safe to handle. Visible distress overrides the desire to confirm a number.
The callout below gives concrete when-to-call-the-vet thresholds for each vital sign: temperature, heart rate and resting respiratory rate, plus weight or body-condition changes that need attention. Treat these as screening boundaries rather than diagnoses, and follow a veterinarian's narrower instructions when your pet has a known condition or an individual baseline outside the general range.
- Call your veterinarian promptly for a resting breathing rate above 35 breaths per minute; a resting heart rate below 60 in a large dog, below 70 in a small dog, above 180 in any dog, below 150 or above 220 in a cat; a rectal temperature below 99 or above 104 degrees Fahrenheit; or an unexplained weight or body condition change. Labored breathing, blue or very pale gums, collapse, severe weakness, seizures or an unresponsive pet require emergency care now.
The urgent heart-rate limits above come from the Merck Veterinary Manual triage table: it separately lists normal resting ranges and flags bradycardia below 60-70 in dogs or 150 in cats, and tachycardia above 180 in dogs or 220 in cats. A calm, repeated result outside the normal chart still deserves veterinary consultation even when it has not crossed an urgent triage boundary. The breathing threshold follows Cornell veterinary guidance, and the temperature emergency points match veterinarian-authored guidance on taking a pet's temperature. These are screening boundaries, not diagnoses; your veterinarian may set a narrower action point for a pet with a known condition.
This guide combines dog and cat how-to steps with a normal-ranges chart, weight and body-condition tracking, escalation thresholds and a reusable at-home vitals log. The single dog-and-cat chart, per-vital call-the-vet thresholds and monthly log form one decision framework that owners can reuse between veterinary visits, compare with earlier readings and share with the veterinary team when a trend changes.
Pet Vital Sign FAQs
TPR stands for temperature, pulse and respiration. This mnemonic device helps you check your pet's vital signs in a consistent order: first temperature when safe, then pulse or heart rate, then resting respiration. TPR names the three main vital signs in animals, while weight and body condition belong in the same written trend log. Always record whether the pet was resting, stressed, active, panting or purring, because context changes how a number should be interpreted.
