Importance Of Panting

Proper muzzle use saves lives. Improper muzzle use puts dogs at risk—of overheating, injury, or worse. Always prioritize fit, comfort, and your dog’s ability to pant and breathe freely. Muzzles should support training and safety and never at the expense of your dog's health.

Why Panting Matters


Panting is a vital cooling mechanism for dogs. Unlike humans, dogs don’t sweat through their
skin—instead, they cool down primarily through their mouth and tongue. When a dog pants, it
evaporates moisture from the tongue and mouth, helping regulate body temperature and oxygenate the blood. Preventing a dog from panting, especially in warm or stressful conditions, can quickly lead to overheating/heat stroke.


Dogs may pant for many reasons, including:

  • Physical activity or play
  • Warm weather or heat exposure
  • Stress/anxiety or even excitement

 

What Is Heat Stroke and Why Is It Dangerous?

 

“Heat stroke is a term commonly used for hyperthermia or elevated body temperature...
Excited or excessively exercised dogs are sometimes at risk even if the environmental
temperature and humidity do not seem high.”
– Dr. Krista Williams, BSc, DVM, CCRP; Dr. Ernest Ward, DVM

 

Heat stroke can occur when a dog’s body temperature rises above 103°F (39.4°C). It’s a
life-threatening emergency and is often caused by:

  • Being left in a car without ventilation
  • Lack of access to shade or water
  • Exercise in hot conditions
  • Stress or excitement 
  • Being brachycephalic (Boxers, Frenchies etc)


Muzzles that restrict panting increase the risk of heat stroke dramatically, especially in these conditions. Yet many companies still promote small, restrictive muzzles that can cause serious harm when used incorrectly.

 

Restrictive Muzzles and Vomiting Risks


A commonly overlooked danger of overly tight muzzles is the inability to vomit safely. If a dog vomits
while wearing a restrictive muzzle and can’t open its mouth fully, it may choke or aspirate vomit into its
lungs—potentially leading to life-threatening pneumonia.

Closed Mouth Height

This refers to the height of your dog’s muzzle when their mouth is fully closed. A properly fitted muzzle should never be this small—or smaller. If a muzzle matches the closed-mouth height, it's dangerously tight. This can restrict normal breathing, increase the risk of choking (especially if the dog vomits) or heat stroke. Or cause painful rubbing or pressure sores, and lead to serious stress or anxiety.

 

 

Regular Pant
This is the typical panting your dog does during everyday activities—like a casual walk, a short play session, or a visit to the vet or groomer. It's more open than a closed mouth and less than a full, heavy pant. A muzzle should allow room for this level of panting to ensure your dog can stay cool and comfortable during routine outings.

Full Pant
This is your dog’s widest pant, typically seen after intense exercise, playing tug, doing sports, experiencing high stress, or being out on a hot day. A muzzle must allow enough space for a full pant when needed—this is crucial for your dog’s safety and comfort. If a muzzle restricts your dog’s ability to fully pant, it can lead to overheating, stress, and serious health risks.
