Dog Vital Signs: How to Monitor, What’s Normal & Warning Signals
Simple pulse, breathing, and temperature checks reveal early wellness shifts at home.
Understanding Your Dog’s Vital Signs
Being able to monitor your dog’s vital signs is one of the most valuable health skills a pet parent or caregiver can acquire. Knowing what is normalâand what requires veterinary attentionâcan help keep your dog healthy, safe, and potentially save their life. This guide breaks down the essential canine vital signs, how to check them at home, what numbers are normal, and the warning signals you should never ignore.
What Are “Vital Signs” for Dogs?
The three primary vital signs for dogs are:
- Heart Rate (Pulse)
- Respiratory Rate
- Body Temperature
Each of these measurements provides critical information about your dogâs internal health and helps indicate if something may be wrong that needs attention.
Normal Dog Vital Sign Ranges
While individual dogs may vary based on breed, age, and health status, the following ranges are considered typical for adult dogs at rest:
| Vital Sign | Normal Range |
|---|---|
| Heart Rate | 70-140 beats per minute (bpm) |
| Respiratory Rate | 10-35 breaths per minute |
| Body Temperature | 100â102°F (37.8â39°C) |
Puppies often have slightly higher heart and respiratory rates. Senior dogs may be on the lower end of these scales.
How to Check Your Dogâs Vital Signs at Home
Before you start, make sure your dog is calm and ideally at rest. Excitement, play or stress can temporarily elevate vital signs, leading to misleading numbers.
Checking Heart Rate (Pulse)
- Have your dog lie down or stand quietlyâensure theyâre relaxed.
- Locate the femoral artery:
- Run your fingers high on the inside of your dogâs thigh near where the leg meets the abdomen.
- Press gently with your fingertips (not your thumb) until you feel a pulsing sensation.
- Count the number of pulses in 15 seconds.
- Multiply that number by 4 to get the pulse rate (beats per minute).
Example: If you count 22 pulses in 15 seconds, 22 x 4 = 88 bpm.
Checking Respiratory Rate
- With your dog at rest, observe the rise and fall of their chest.
- One full rise and fall equals one breath.
- Count the total breaths for 15 seconds, then multiply by 4 to find the respiratory rate per minute.
Example: 8 breaths in 15 seconds x 4 = 32 breaths per minute.
Checking Body Temperature
The most accurate way to measure a dogâs body temperature is with a digital rectal thermometer:
- Lubricate the thermometer tip with petroleum jelly.
- Gently insert the thermometer about 1 inch into your dogâs rectum.
- Wait until the thermometer beeps; gently remove it and check the reading.
For dogs who resist or if youâre uncomfortable with this method, ask your veterinarian to demonstrate the process. Ear thermometers are less accurate but may be used for a quick check.
When and Why You Should Check Vital Signs
- If your dog seems unwell, sluggish, or has a change in behavior
- After exposure to heat, heavy exercise, or any incident where overheating may occur
- If you observe signs of illness such as vomiting, diarrhea, or unexplained lethargy
- Routinely as part of regular health checksâespecially for senior dogs or dogs with chronic health conditions

10 Signs Your Dog May Be Sick (and Need a Vet)
Itâs not always easy to tell when a dog is unwell since they instinctively mask signs of discomfort. The following warning signals should prompt immediate attention and, where indicated, a call to your veterinary professional:
- Bad breath: Persistent foul or fruity odor, uncontrolled drooling, pale or jaundiced gums
- Distended abdomen: Sensitive, swollen belly or excessive gas
- Change in appetite or thirst: Sudden refusal to eat/drink or dramatic increases
- Movement difficulties: Stiffness, trouble getting up, or limping
- Lethargy: Unusual sleepiness or decreased activity level
- Labored breathing (dyspnea): Coughing, sneezing, heavy panting, or visible struggle to breathe
- Excessive scratching/itching: Persistent scratching, licking, sores, or lumps
- Vomiting and/or diarrhea: Frequent or severe digestive upset
- Abnormal eye appearance: Involuntary eye movement (nystagmus), redness, discharge, or cloudiness
- Injury signs: Bleeding, trauma, unexplained disorientation, or circling
Any of these signs warrant a closer examination of your dogâs vital signs and potentially a prompt veterinary visit.
Understanding Dog Body Temperature
A dogâs normal temperature is slightly higher than a humanâs. For most healthy dogs:
- Typical range: 100°F to 102°F (38°Câ39°C)
- Low end: 99.5°F (37.5°C)
- High end: 102.5°F (39.2°C)
Anything above 103°F is considered a fever. Temperatures above 105°F are dangerous and could be fatal (heatstroke).
When to Take Your Dogâs Temperature
- If your dog feels noticeably warm to touch, is lethargic, or shows decreased appetite
- After potential exposure to infectious diseases
- In hot weather or if your dog has been active outdoors
Common causes of fever include infections (bacterial, viral, fungal), autoimmune issues, or heatstroke. If your dogâs temperature is outside the normal range, consult your vet promptly.
Key Details About Dog Heart Rate
The typical heart rate for dogs is:
- Small dogs and puppies: 100â160 bpm
- Medium to large adult dogs: 70â140 bpm
- Senior dogs: Often closer to the lower end
The heart rate can temporarily increase due to excitement, exercise, or stress. Always check when your dog is calm and resting for the most accurate data.
If you detect a pulse that is significantly faster, slower, or irregular (especially if accompanied by weakness or collapse), call your veterinarian immediately.
How to Assess Respiratory Rate
Respiratory rates vary by dog and activity level. The normal resting range is:
- 10â35 breaths per minute
- Puppies and toy breeds often breathe faster
Heavy panting after exertion is normal, but rapid, shallow, or labored breathing at rest is cause for concernâespecially if breathing is noisy or the gums appear blue or pale.
Signs of Heatstroke and What to Do
Heatstroke is a veterinary emergency that occurs when a dogâs body temperature soars dangerously highâtypically above 105°F (40.5°C). Key causes include hot weather, overexertion, and confinement in unventilated spaces (such as cars).
- Warning signs of heatstroke:
- Body temperature above 105°F
- Excessive panting or difficulty breathing
- Bright red or pale gums and tongue
- Drooling, vomiting, or diarrhea
- Unsteadiness, collapse, or seizures
If you suspect heatstroke:
- Move your dog to a cool, shaded area
- Offer small amounts of cool (not cold) water
- Use wet towels on their feet, belly, and armpits
- Get veterinary help immediatelyâdo not wait, as organ failure can occur rapidly
Detecting Signs of Stress and Anxiety in Dogs
Stress can show up in subtle or obvious ways and may impact your dogâs vital signs as well as their long-term health. Recognizing stress signals helps you intervene before issues become severe.
Physical Signs of Stress
- Pacing or shaking
- Lip licking, drooling
- Shivering, trembling
- Showing more white of the eyes (“whale eye”)
- Hiding, tail or ears tucked
- Persistent itching or scratching
- Raised hackles
- Compulsive behaviors (such as repeated licking or chewing)
Behavioral Signs of Stress
- Barking or howling without clear cause
- Withdrawing or avoiding people/other pets
- Excessive yawning
- Accidents indoors (urination/defecation)
- Whining, whimpering, or excessive vocalization
- Unusual stiffness or staring
- Refusing treats or food temporarily
If your dog frequently shows these signs, work to identify and minimize possible stressors. Consult a behaviorist or your veterinarian if needed.
Proactive Care: Helping Your Dog Stay Healthy
- Monitor your dogâs vital signs during regular health checks, especially if they are young, old, or have pre-existing medical conditions.
- Observe changes in behavior, appetite, or energy level and note anything unusual.
- Act quickly if you detect values outside the normal ranges or any warning symptoms. Early intervention saves lives.
- Develop a relationship with your veterinarian and donât hesitate to ask them to show you these techniques or clarify concerns.
- Keep a log of your dogâs normal vital sign readings as a reference in emergencies.
