But have you ever wondered why Chihuahuas shake? In this article, we’ll explore some of the reasons why your Chihuahua may be shaking.

Chihuahuas are little dogs with a rapid metabolic rate and low body fat percentage.

This makes them more susceptible to feeling cold, as they lack the insulation of larger dogs.

In addition, Chihuahuas have a very big surface area relative to their body weight, which allows them to shed heat faster than larger dogs.

Chihuahuas may shake to generate heat and maintain their body temperature against this.

Shaking improves blood flow and muscle heat production, which can aid in maintaining body temperature.

Yet, not all Chihuahuas shake as the temperature drops.

Some individuals may shake more than others, while others may not.

If your Chihuahua is shaking more than usual, you should always rule out other explanations.

Anxiety and Stress in Chihuahuas

Anxiety and stress are other causes of Chihuahua trembling.

Chihuahuas are notoriously high-strung and quickly startled, and numerous stimuli can induce anxiety in these small canines.

Chihuahuas commonly experience separation anxiety and may shudder when left alone.

Chihuahuas can also experience nervousness and trembling when exposed to loud noises such as thunderstorms or fireworks.

Unfamiliar circumstances or places can also induce anxiety and tremor.

Furthermore, shaking is only one of Chihuahuas’ numerous signs of nervousness.

Some possible indications include excessive panting, drooling, pacing, and hiding.

If you feel that your Chihuahua is worried, you must address the underlying cause of their worry and, if required, engage with a trainer or behaviorist.

Pain or Discomfort

Chihuahuas may also shake when they are in pain or discomfort.

For instance, Chihuahuas may shake due to tooth abnormalities that cause them pain.

Injuries such as sprains and strains may also result in trembling.

If you feel that your Chihuahua is in pain or discomfort and shaking, you should immediately take them to the veterinarian.

A physical examination and any necessary diagnostic procedures can determine the source of your Chihuahua’s trembling.


Chihuahuas, believe it or not, may also shake when aroused! This is especially true when they are anticipating a reward or walk.

As a Chihuahua becomes aroused, their body may emit adrenaline, causing them to shake.

It is essential to differentiate between trembling due to enthusiasm and shaking due to nervousness.

When a Chihuahua gets excited and trembling, it may wag its tail, bounce up and down, or make joyful sounds.

Yet, when a Chihuahua shakes from nervousness, they may crouch, hide, or display other distressing behaviors.


Chihuahuas shake for various causes, including physiology, worry, stress, pain, discomfort, and excitement.

If you’re wondering why your Chihuahua is shaking, it’s always a good idea to study their behavior and seek other indicators of concern.

If your Chihuahua exhibits other problematic behaviors or symptoms, it is essential to have them examined by a veterinarian.

In addition, it is vital to know that certain Chihuahuas may shake because this is a typical habit for their breed.

If your Chihuahua is trembling but is generally healthy content and not exhibiting any other alarming behaviors, their trembling is likely a quirk of their personality.

If you are concerned about your Chihuahua’s trembling, there are steps you can take to help.

For instance, if your Chihuahua is shivering because of chilly weather, you can present them with a warm, cuddly blanket or sweater to keep them warm.

Suppose your Chihuahua is trembling due to anxiety or stress.

In that case, you can work with a trainer or behaviorist to address the underlying source of their discomfort and help them feel calmer and more relaxed.

In addition, if your Chihuahua is trembling due to pain or discomfort, your veterinarian can prescribe drugs or other treatments to reduce their symptoms.

To discover the source of a Chihuahua’s trembling, monitoring the dog’s behavior and searching for other indicators of discomfort is necessary.

By understanding why your Chihuahua is shaking, you can make them feel more comfortable, relaxed, and content.

Remember that a bit of shaking is part of what makes Chihuahuas such fascinating and affectionate friends!
