To check your dog’s vital signs, focus on four key areas: temperature, heart rate, respiratory rate, and mucous membranes. Use a digital thermometer to check rectal temperature (normal is 100°F–102.5°F). Feel the femoral artery inside the thigh to count heart rate (normal is 60–140 beats per minute, depending on size). Watch chest movements for respiratory rate (normal is 10–30 breaths per minute). Finally, press on the gums to check Capillary Refill Time (CRT), which should return to pink in under 2 seconds.

How to Check Your Dog’s Vital Signs at Home
Knowing how to perform a basic health check on your dog is one of the most valuable skills a pet owner can have. Dogs are experts at hiding pain. By the time they show obvious symptoms like limping or whining, an illness might already be advanced.
Learning to check your dog’s vital signs allows you to establish a baseline of what is “normal” for your specific pet. This makes it much easier to spot when something is wrong.
This guide will walk you through exactly how to check the five most important health indicators: temperature, pulse, respiration, mucous membranes, and hydration.
We have removed the medical jargon and focused on simple, actionable steps you can take in your living room.

Preparing to Check Vital Signs
Before you start poking and prodding, you need to set the scene. If your dog is stressed, their heart rate and temperature will naturally rise, giving you false readings.
Gather Your Toolkit
You don’t need a full medical bag, but a few specific items are necessary:
- Digital Thermometer: A standard human digital thermometer works best. Label it clearly “DOG ONLY” to avoid household mix-ups.
- Lubricant: Petroleum jelly or a water-based lubricant is essential for taking a temperature safely.
- Timer: Your smartphone’s stopwatch or a watch with a second hand.
- Flashlight: To help see gum color or check inside ears.
- Treats: High-value rewards to keep your dog calm and happy.
Set the Mood
Choose a quiet room away from other pets or loud noises. If your dog is anxious, spend five minutes just petting them before you begin. Ideally, you want your dog standing up or lying on their side.
If you have a large dog, you can do this on the floor. For small dogs, placing them on a sturdy table with a non-slip mat can make it easier to reach them.
1. Body Temperature: The Gold Standard
A dog’s temperature is the most reliable indicator of infection, inflammation, or heat stroke. Unlike humans, you cannot tell if a dog has a fever by touching their forehead or nose. The only accurate method is a rectal temperature check.
Step-by-Step Guide
- Prep the thermometer: Apply a generous amount of lubricant to the tip of the digital thermometer.
- Secure the dog: If your dog is standing, have a helper gently hold their head and hug their front shoulders. If you are alone, you can position the dog against a wall to prevent them from backing away.
- Lift the tail: Lift the base of the tail gently.
- Insert: Gently insert the thermometer about one inch into the rectum. Do not force it.
- Wait for the beep: Hold the thermometer steady until it beeps.
- Remove and clean: Remove gently, read the number, and clean the device thoroughly with alcohol.
What is Normal?
- Normal: 100°F to 102.5°F.
- Fever: Above 103°F.
- Emergency: Above 104°F or below 99°F.
Important Note: Ear thermometers designed for dogs exist, but they are often less accurate than rectal thermometers. If you use an ear thermometer, follow the manufacturer’s instructions strictly, as the angle of the probe matters significantly.
2. Heart Rate and Pulse
Your dog’s heart rate tells you how hard their heart is working. A rate that is too fast or too slow can indicate heart disease, shock, pain, or anxiety. While you can feel the heartbeat on the chest, feeling the pulse ensures that blood is actually circulating effectively to the limbs.
Finding the Femoral Artery
The best place to find a pulse is the femoral artery.
- Have your dog stand or lie on their side.
- Place your fingers (not your thumb) on the inside of the hind leg, high up where the leg joins the body (the groin area).
- Press gently until you feel a rhythmic tapping sensation. It may take a few tries to find it, so be patient.
How to Count
Once you find the pulse:
- Start your timer.
- Count the beats for 15 seconds.
- Multiply that number by 4 to get the Beats Per Minute (BPM).
Example: You count 20 beats in 15 seconds. 20 x 4 = 80 BPM.
Normal Ranges by Size
- Puppies: 120 – 160 BPM (they have faster metabolisms).
- Small/Toy Breeds: 100 – 140 BPM.
- Medium/Large Breeds: 60 – 100 BPM.
Pro Tip: If you cannot find the femoral pulse, place your hand over the left side of the dog’s chest, just behind the elbow. This allows you to feel the heart beating directly, though it does not confirm pulse strength.

3. Respiratory Rate
Respiratory rate is simply the number of breaths your dog takes in one minute. This is a crucial vital sign for dogs with heart issues, as an increased rate can be the first sign of heart failure.
How to Measure Correctly
This must be done when the dog is resting quietly or sleeping. It should not be done immediately after exercise or when the dog is panting. Panting is a cooling mechanism, not a normal respiratory rate.
- Watch your dog’s chest.
- Count one “breath” when the chest rises and falls. (In + Out = 1 Breath).
- Count for a full 60 seconds for the most accuracy, or 30 seconds and multiply by 2.
What is Normal?
- Resting Rate: 10 to 30 breaths per minute.
- Abnormal: Anything consistently over 35-40 breaths per minute while resting is a red flag.
If your dog is breathing with their mouth open, extending their neck, or if their stomach is heaving with every breath, this is respiratory distress. This is an emergency.
4. Mucous Membranes and Capillary Refill Time (CRT)
The color of your dog’s gums and how quickly blood returns to them gives you immediate information about blood circulation and oxygen levels.
Checking Gum Color
Lift your dog’s upper lip gently. Look at the gum tissue above the teeth (avoid pigmented spots if your dog has black spotted gums).
- Pink (Bubblegum): Normal and healthy.
- Pale or White: Anemia, blood loss, or shock.
- Blue or Purple (Cyanotic): Lack of oxygen. This is a critical emergency.
- Bright Red: Heat stroke, sepsis, or carbon monoxide poisoning.
- Yellow (Jaundiced): Liver issues.
The Capillary Refill Time (CRT) Test
This test checks how fast blood fills the tiny capillaries in the gums.
- Lift the lip.
- Press your finger firmly onto a pink area of the gum for 2 seconds (it will turn white).
- Release your finger.
- Count how many seconds it takes for the pink color to return.
The Result: The color should return to pink in less than 2 seconds. If it takes 3 seconds or longer, your dog may have poor circulation, dehydration, or be in shock.
5. Hydration Level (Skin Turgor)
Water is critical for life. Dogs can become dehydrated quickly from vomiting, diarrhea, or overheating. You can check hydration using the “Skin Turgor” test.
The Tent Test
- Gently pinch a loose fold of skin over the dog’s shoulder blades or the back of the neck.
- Lift it up to form a “tent.”
- Release it.
Interpreting the Result
- Well Hydrated: The skin snaps back into place instantly.
- Dehydrated: The skin slowly slides back into place or stays tented for a few seconds.
- Sticky Gums: Another sign of dehydration is dry, tacky gums rather than moist, slippery ones.

Creating a Baseline Health Log
Checking these vitals once is helpful, but checking them regularly is powerful. Every dog is different. A heart rate of 60 might be normal for a Mastiff but dangerously low for a Chihuahua.
We recommend creating a “Normal Health Log” for your pet.
- Pick a quiet evening.
- Run through all five tests.
- Write down the results.
- Repeat this once a month.
Having this data ready for your veterinarian can speed up a diagnosis significantly. If you call the vet and say, “My dog is sick,” they will ask questions. If you say, “My dog is lethargic, his temperature is 103.5, and his gums are pale,” they will likely tell you to come in immediately.
When to Call the Veterinarian
Knowing the numbers is only half the battle. You need to know when those numbers indicate a crisis. Call your vet immediately if you observe:
- Temperature: Over 104°F or under 99°F.
- Gums: White, blue, or bright red gums.
- Pulse: An erratic, irregular rhythm (skipping beats) or a rate far exceeding the normal range for their size.
- Breathing: Labored breathing, loud gasping sounds, or a resting rate over 40 breaths per minute.
- Responsiveness: If your dog is unresponsive or collapses during your check.
Conclusion
You do not need to be a veterinary professional to monitor your dog’s health. By mastering these simple checks, Temperature, Pulse, Respiration, CRT, and Hydration, you become the first line of defense for your pet.
Start practicing today when your dog is healthy. Use plenty of treats to make it a positive experience. The more comfortable you are performing these checks, the calmer you will be if an emergency ever arises. Your quick action and accurate information could one day save your dog’s life.
