Brittany Spaniel Breathing Heavy: Should I Worry?

Heavy breathing or panting can be described as rapid labored breathing by a Brittany Spaniel which is not a normal breathing pattern.

The average breathing rate of a Brittany Spaniel is between 15 to 35 breaths per minute while at rest and a breathing rate higher than this translates to heavy breathing.

It is normal for a Brittany Spaniel to breathe heavily or pant after exercising, playing, walking, or during hot weather. 

However, generally, dog breathing should not be difficult and you need to differentiate when it’s normal and when you need a visit to the veterinarian.

Heavy breathing can be due to an underlying health problem that causes a Brittany Spaniel to have rapid breathing.

Respiratory disorders, Cushing’s disease, and heart failure are diseases that cause heavy breathing along with other symptoms.

Respiratory disorders include respiratory infection, tracheal collapse, and laryngeal paralysis.


When a Brittany Spaniel is stressed or anxious they tend to be restless, irritable, and have an increased heart rate, rapid breathing, or shortness of breath.

Common reasons for anxiety in Brittany Spaniel include fear, abandonment, trauma, travel, loud noise, new environments, people, or other pets.


Trauma or injury can lead to a Brittany Spaniel breathing heavily because of the pain experienced. The injury could be external or internal causing discomfort and pain.

An injured Brittany Spaniel will also show other signs indicating they are experiencing pain such as loss of appetite, restlessness, enlarged pupils, reluctance to be touched or to lie down, licking of the injured area, and anxiety.

Panting or heavy breathing can also be due to overheating. This occurs when a Brittany Spaniel’s temperature rises due to extreme heat from its environment.

This leads to heat stroke which is fatal. Signs of a Brittany Spaniel with heatstroke include heavy breathing, drooling, glassy eyes, weakness, increased heart rate, increased body temperatures, vomiting, diarrhea, and seizures.


If a Brittany Spaniel is under medication, some medication can lead to heavy breathing.

Smoke inhalation

Smoke inhalation occurs when a Brittany Spaniel inhales smoke from products on combustion. The smoke inhaled causes inflammation of the lungs and airways which swell and prevent oxygen uptake. 

This leads to respiratory distress and a Brittany Spaniel breathing heavy in an attempt to breathe to get more oxygen 

Vigorous activity

It is normal for a Brittany Spaniel to breathe heavily after exertion from vigorous activity such as exercise or from playing.

During these activities, the muscles of a dog require more oxygen, therefore, the heart pumps faster to supply more blood to the organs and the lungs supply the oxygen, which results in heavier breathing and rapid heartbeat.


Heavy breathing for a Brittany Spaniel is not normal and should always be taken as an emergency especially when it’s not due to normal activities such as exercise or hot weather.

Because breathing heavily can be caused by various conditions that can be life-threatening it is important to seek medical help. 

If left untreated, the condition can lead to fatal outcomes and even death.

  • Excessive drooling
  • Heavy breathing especially while sleeping or resting
