Normal vs. Excessive Panting in Dogs

Panting is how dogs regulate their body temperature, as they don’t sweat the way humans do. However, it’s important to differentiate between normal panting and excessive panting, which could indicate discomfort or illness.

When Panting is Normal

• After physical activity or playtime
• During hot or humid weather
• When a dog is excited, anxious, or stressed

When Panting May Be a Concern

• Occurs at rest or without an obvious reason
• Sounds louder or harsher than usual
• When your dog’s gum color is pale or purple
• Accompanied by drooling, coughing, or lethargy
• Persists for an extended period

If your dog is panting excessively and you’re not sure why, it’s always best to consult your veterinarian.

Heat and Overheating: A Common Cause of Excessive Panting

One of the most common reasons dogs pant is to cool down. Dogs use panting to regulate their body temperature, but excessive panting can be a sign of heat exhaustion or even heatstroke.

Signs of Heat Exhaustion or Heatstroke

• Heavy panting and excessive drooling
• Bright red gums or tongue
• Weakness or collapse
• Vomiting or diarrhea
• Glazed eyes or disorientation

Heatstroke is a serious medical emergency that requires immediate veterinary attention. To prevent overheating, always provide plenty of water, avoid walking your dog in extreme heat, and ensure they have a cool, shaded area to rest.

Can Emotional Distress Cause Heavy Panting?

Dogs pant not just from heat but also due to emotional stress. If your dog pants excessively in certain situations, stress or anxiety might be the cause.

Common Triggers of Anxious Panting

• Loud noises such as fireworks or thunderstorms
• Car rides or new environments
• Separation from their owner
• Encounters with unfamiliar people or animals

If stress-induced panting happens often, it may be worth discussing anxiety management strategies with your veterinarian. The team at Lane Veterinary can help you assess your dog’s behavior and recommend ways to reduce their stress.

Pain or Discomfort: Could Panting Indicate an Underlying Health Issue?

Dogs may pant excessively if they are in pain, even if they don’t show obvious signs of discomfort. Since dogs instinctively hide their pain, panting can sometimes be an early indicator of an issue.

Health Conditions That May Cause Panting

• Arthritis or joint pain – Older dogs with joint problems may pant more due to chronic pain.
• Respiratory conditions – Conditions like pneumonia or laryngeal paralysis can make breathing difficult.
• Heart disease – Dogs with congestive heart failure may pant more frequently due to reduced oxygen levels.

If your dog’s panting is paired with other symptoms such as limping, coughing, or fatigue, it’s a good idea to schedule an appointment with your veterinarian.

Metabolic Disease: A Hidden Cause of Excessive Panting

Certain metabolic diseases can lead to increased panting in dogs. These conditions affect the body’s ability to regulate hormones and energy levels, which may result in excessive panting.

Common Metabolic Diseases That Cause Panting

• Cushing’s disease (Hyperadrenocorticism) – An overproduction of cortisol can lead to excessive panting, increased thirst, and weight gain.
• Diabetes mellitus – High blood sugar levels may cause panting due to increased thirst and dehydration.
• Hypothyroidism – An underactive thyroid can slow metabolism and lead to panting, lethargy, and weight gain.

If your dog’s panting is accompanied by other symptoms such as changes in appetite, weight fluctuations, or increased water consumption, your veterinarian can perform tests to determine if a metabolic disorder is the cause.

Is Your Dog’s Medication a Factor?

Some medications can cause increased panting as a side effect. If your dog recently started a new prescription and you’ve noticed heavier panting, this could be the reason.

Medications That May Cause Increased Panting

• Steroids (Prednisone, Prednisolone) – Commonly prescribed for inflammation, but may cause panting as a side effect.
• Pain medications – Some pain relievers can affect your dog’s respiration.

If you suspect your dog’s medication is causing excessive panting, consult your veterinarian before making any changes.

Respiratory Problems: Is Your Dog Struggling to Breathe?

Certain breeds are more prone to respiratory issues that can lead to excessive panting. Brachycephalic breeds, such as Bulldogs, Pugs, and Shih Tzus, often have breathing difficulties due to their shortened snouts.

Signs of Respiratory Distress

• Noisy breathing or wheezing
• Open-mouth breathing at rest
• Blue-tinged gums (a sign of low oxygen levels)
• Labored or strained breathing

If your dog struggles to breathe or frequently pants with no obvious cause, immediate veterinary care is necessary.

When to Call Your Veterinarian About Your Dog’s Panting

If you’re still wondering, “why is my dog panting so much?” and none of the usual reasons seem to fit, it’s time to seek professional advice. While occasional panting is normal, excessive panting can sometimes indicate an underlying health issue that needs medical attention.

Red Flags Signaling It’s Time to Schedule a Vet Visit

• Your dog pants heavily at rest with no clear reason
• Panting is accompanied by coughing, drooling, or fatigue
• There are signs of pain, anxiety, or distress
• Your dog has a history of respiratory or heart conditions
