Why does a dog shiver when inhaling? - briefly

A dog may shiver while inhaling due to an irritation or obstruction in its respiratory system. This can be caused by various factors such as allergens, foreign objects, or underlying health issues like kennel cough or asthma.

Why does a dog shiver when inhaling? - in detail

When a dog inhales and shivers, it is often due to a reflex known as "thoracic breathing." This type of breathing is characterized by the expansion of the chest cavity rather than the abdomen, which is typical in most mammals during normal respiration. In dogs, this reflex can be triggered by various factors, including excitement, fear, or even anticipation of food or play.

The shivering movement is a result of the intercostal muscles (the muscles between the ribs) contracting rapidly to facilitate quick and deep breaths. This allows the dog to take in more oxygen, which can be crucial during times of high physical activity or emotional stress. The rapid contraction and expansion of the chest create a shiver-like motion, which is why it appears as if the dog is shivering.

Additionally, dogs may exhibit this behavior when they are experiencing discomfort or pain in their abdominal area. In such cases, shallow breathing from the chest can be more comfortable than deep breaths that would involve the expansion of the abdomen.

It is important to note that while thoracic breathing and shivering are common in dogs, persistent or excessive shivering during inhalation could indicate an underlying health issue, such as respiratory problems or anxiety disorders. If you notice your dog exhibiting this behavior frequently or with increasing intensity, it may be wise to consult a veterinarian for a thorough evaluation.
