Chihuahuas, with their large, expressive eyes and spirited personalities, are undeniably captivating. Their petite size and confident demeanor have made them a favorite among dog lovers. However, one peculiar behavior often observed in these little dynamos is their tendency to tremble or shake, leaving many owners wondering: “Why Do Chihuahuas Tremble?”
It’s true that shaking is a relatively common characteristic in Chihuahuas. Sometimes it’s perfectly normal, and other times, it can signal an underlying issue that needs your attention. Understanding the reasons behind this shaking is key to ensuring your Chihuahua’s well-being. Let’s delve into the common causes of trembling in Chihuahuas, helping you discern when it’s just a quirk and when it might be a cause for concern.
Is Shaking Normal for a Chihuahua?
Yes, in many cases, shaking is indeed normal for Chihuahuas. These small dogs are more susceptible to feeling the cold and are naturally more reactive to stress, both of which can trigger tremors.
As a toy breed, Chihuahuas possess a fast metabolism and less body fat compared to larger breeds. This combination means they lose heat more quickly and are more prone to feeling chilly, even in mildly cool environments. Their nervous systems are also finely tuned, making them more sensitive to environmental changes and emotional stimuli, leading to a higher likelihood of nervous shaking.
While occasional shaking is often nothing to worry about, persistent or frequent trembling in your Chihuahua warrants closer observation. If your furry friend is shaking excessively or daily, it’s important to investigate further to rule out any potential health problems or significant stressors.
Why Do Chihuahuas Shake and Shiver? 5 Common Reasons
There are various reasons why your Chihuahua might be shaking. Understanding these can help you determine the cause and take appropriate action.
1. Cold Temperature: The Chill Factor
Chihuahuas, with their delicate builds and thin coats, are particularly sensitive to cold. Their low body weight and minimal fur insulation mean they can quickly lose body heat. Shivering is a natural physiological response to cold – muscle contractions generate heat in an attempt to raise body temperature and combat the chill.
If you observe your Chihuahua shaking and notice other signs of being cold, such as seeking out warm spots, decreased activity, curling up tightly, or even pale or bluish gums, it’s highly likely that the shaking is simply their body’s way of warming up. Providing a warm sweater, a cozy blanket, or adjusting the room temperature can often resolve this type of shivering.

2. Fear and Anxiety: The Nervous Chihuahua
Chihuahuas are known for their spirited and sometimes anxious personalities. Their heightened sensitivity can make them easily startled or overwhelmed in unfamiliar or stressful situations. Fear and anxiety are significant triggers for shaking in this breed.
When a Chihuahua feels threatened, anxious, or encounters something frightening, their body releases adrenaline and other stress hormones. These hormones can lead to a variety of physical responses, including trembling, increased heart rate, rapid breathing, and panting. If your Chihuahua is shaking and also exhibiting other signs of fear, such as cowering, tucking their tail, hiding, or excessive barking, anxiety or fear is likely the culprit. Identifying and removing the source of stress, or employing calming techniques, can help alleviate anxiety-induced shaking.

3. Excitement: Happy Trembles
Not all shaking in Chihuahuas is negative! Believe it or not, excitement and happiness can also manifest as trembling in these enthusiastic little dogs. When Chihuahuas get overly excited, whether it’s due to your arrival home, the prospect of a walk, or engaging in playful activities, they might start to shake.
This type of shaking is usually accompanied by other positive indicators of excitement, such as a wagging tail, playful jumping, “zoomies” (bursts of frantic running around), and an overall joyful demeanor. This is simply an expression of their exuberance and is generally harmless and endearing.
4. Hypoglycemia (Low Blood Sugar): A Serious Condition
Chihuahuas are predisposed to hypoglycemia, a condition characterized by dangerously low blood sugar levels. Due to their small size and rapid metabolism, they can quickly deplete their glucose reserves, making them susceptible to this condition, especially puppies and toy breeds.
When a Chihuahua’s blood sugar drops too low, their body struggles to produce enough energy for normal function. This can lead to a range of symptoms, including shaking, lethargy, weakness, confusion, disorientation, seizures, and even loss of consciousness. Hypoglycemia is a serious condition that requires prompt veterinary attention.
If you suspect your Chihuahua is hypoglycemic, especially if the shaking is accompanied by weakness, lethargy, or disorientation, it’s crucial to seek immediate veterinary care. A veterinarian can perform blood tests to confirm hypoglycemia and administer glucose to raise blood sugar levels quickly. Treatment may also involve dietary adjustments and management strategies to prevent future episodes. In emergency situations, and only under veterinary guidance, applying a small amount of corn syrup or honey to the gums can provide a temporary sugar boost while seeking professional help.

5. Underlying Health Problems: When Shaking is a Symptom
In some instances, persistent or unexplained shaking in Chihuahuas can be a symptom of an underlying medical condition. Various health issues can manifest as tremors, and it’s essential to rule out these possibilities, especially if the shaking is new, worsening, or accompanied by other symptoms. Potential health issues linked to shaking include:
- Pain: Pain from injuries, arthritis, or other conditions can cause shaking as a stress response.
- Arthritis: Joint pain and inflammation associated with arthritis can lead to tremors, particularly in older Chihuahuas.
- Neurological Issues: Certain neurological disorders can affect muscle control and coordination, resulting in shaking or tremors.
- Generalized Tremor Syndrome (GTS): Also known as “Little White Shaker Syndrome,” although it can affect dogs of any color, GTS is an inflammatory condition of the central nervous system that causes full-body tremors.
- Kidney Disease: Toxins building up in the bloodstream due to kidney dysfunction can sometimes cause neurological symptoms, including tremors.
If your Chihuahua’s shaking is accompanied by other concerning symptoms like limping, vomiting, diarrhea, loss of appetite, lethargy, changes in behavior, or seizures, it is imperative to consult with a veterinarian promptly to diagnose and address any potential underlying health issues.
Why Do Chihuahuas Shake in Their Sleep?
You might also observe your Chihuahua shaking or twitching while they are sleeping. This is a fairly common occurrence in dogs, including Chihuahuas, and usually not a cause for alarm.
These sleep tremors are generally believed to be related to the dream state. During sleep, dogs, like humans, experience different sleep cycles, including periods of active sleep where dreaming occurs. During these dream cycles, the brain is highly active, processing experiences and emotions from the day. This brain activity can sometimes trigger involuntary muscle movements and twitches, including shaking.
Think of it like humans who might talk or move in their sleep. Chihuahuas in an active dream state might involuntarily shake or twitch as a result of signals from their brain reaching their muscles. It’s similar to how we might jolt awake from a nightmare or experience a physical sensation in response to a dream.
While occasional shaking or twitching during sleep is generally normal, it’s still wise to monitor your Chihuahua’s overall health and behavior. If you notice significant changes in their sleep patterns, if they seem distressed during sleep, or if the shaking is excessive or accompanied by other worrying signs, a check-up with your veterinarian is always a good idea to rule out any underlying concerns.
How to Help Your Chihuahua Stop Shaking
The approach to stopping your Chihuahua’s shaking depends entirely on the underlying cause. If you suspect hypoglycemia or a more serious health issue, immediate veterinary attention is paramount.
However, if your Chihuahua is shaking due to anxiety, stress, or cold, there are several steps you can take to help calm them and reduce the tremors:
Create a Safe and Cozy Space
Providing your Chihuahua with a secure and comfortable sanctuary can significantly reduce anxiety-related shaking. Designate a quiet and safe space for them, such as a crate or a comfortable bed in a peaceful room. This space should be their haven, a place where they can retreat and feel protected.
Consider your Chihuahua’s individual preferences when setting up their safe space. Some Chihuahuas prefer the den-like security of a crate, while others might prefer an open bed or cushion. Ensure the space is located away from loud noises, high traffic areas, and other potential stressors. Adding soft blankets, pillows, and familiar toys can further enhance the sense of comfort and security.

Utilize Calming Techniques
Various calming techniques can help soothe an anxious Chihuahua and reduce shaking. Pheromone sprays or diffusers that release calming scents can create a more relaxed atmosphere. Lavender is a scent often associated with relaxation and can be beneficial.
Playing soft, calming music, particularly classical music or melodies designed for dogs, can also have a soothing effect. Studies have indicated that certain types of music can reduce stress and anxiety in dogs, promoting a calmer state of mind.
For some anxious Chihuahuas, natural remedies like CBD oil or herbal calming supplements may be beneficial. However, always consult with your veterinarian before introducing any new supplements to your dog’s routine to ensure safety and appropriate dosage.
Ensure Adequate Exercise and Playtime
Regular physical activity is crucial for a Chihuahua’s overall well-being and can be particularly helpful in managing anxiety and reducing shaking related to pent-up energy or stress. Chihuahuas, despite their small size, still need daily exercise and mental stimulation.
Engage your Chihuahua in regular walks, play sessions, and interactive games. Physical activity helps them burn off excess energy, reduces stress hormones, and promotes mental well-being. Adequate exercise can contribute to a calmer demeanor and reduce the likelihood of shaking due to over-excitement or anxiety.
My Chihuahua Still Won’t Stop Shaking: When to Seek Veterinary Advice
If your Chihuahua’s shaking persists despite your efforts to address potential triggers like cold or anxiety, or if it becomes a frequent or daily occurrence, it’s important to seek veterinary guidance. Persistent shaking, especially if accompanied by other symptoms, could indicate an underlying health condition that requires diagnosis and treatment.
If you’ve implemented calming techniques, ensured a comfortable environment, and ruled out obvious causes like cold, but your Chihuahua continues to shake frequently, schedule an appointment with your veterinarian. They can perform a thorough examination, run diagnostic tests if needed, and determine the underlying cause of the shaking. Early veterinary intervention is crucial for addressing potential health issues and ensuring your Chihuahua’s long-term health and happiness.
Bottom Line: Understanding Why Chihuahuas Tremble
Witnessing your Chihuahua shaking can be concerning, but it’s important to remember that there are numerous reasons behind this behavior. While some causes, like cold or excitement, are perfectly normal and easily addressed, others, such as hypoglycemia or underlying health issues, require veterinary attention.
By carefully observing your Chihuahua’s shaking, noting any accompanying symptoms, and considering the context in which it occurs, you can often determine the likely cause. When in doubt, or if the shaking is persistent or worrisome, always err on the side of caution and consult with your veterinarian. Proactive care and a good understanding of your Chihuahua’s behavior are essential for ensuring a happy, healthy, and tremor-free life for your beloved tiny companion.
