Chihuahuas, with their distinctive big eyes and spirited personalities, are a much-loved breed. However, one trait that frequently concerns Chihuahua owners is their tendency to shake or tremble. It’s a common question: Why Do Chihuahuas Shake?
The reality is, shaking is indeed a prevalent behavior in Chihuahuas. While in many cases, this shaking is perfectly normal and harmless, in other instances, it can be an indicator of an underlying issue that needs attention.
So, when should you be concerned about your Chihuahua’s shaking, and what are the various reasons behind this behavior? Let’s delve into the common causes of shaking in Chihuahuas and explore what you can do to help your tiny companion.
Is Shaking Normal for Chihuahuas?
Yes, it is generally considered normal for Chihuahuas to shake. This is especially true when they are experiencing moments of anxiety or feeling cold. Several factors contribute to this predisposition in Chihuahuas.
Firstly, as a toy breed, Chihuahuas have a naturally faster metabolism compared to larger dogs. This rapid metabolism can make them more susceptible to feeling cold, as they may burn through energy quicker. Secondly, Chihuahuas possess less body fat. Fat acts as insulation, and with less of it, they are more sensitive to temperature changes and are likely to feel chilly even in mildly cool environments.
Furthermore, Chihuahuas are known to have a more sensitive nervous system. This heightened sensitivity means they can be more reactive to stress, excitement, and anxiety. This neurological predisposition can also manifest as shaking or trembling.
While occasional shaking is usually not a cause for alarm, frequent or excessive shaking in your Chihuahua is something to pay attention to. If you notice your Chihuahua shaking on a daily basis or very often, it’s important to investigate further to rule out any potential health concerns or environmental triggers.
Why Do Chihuahuas Shake and Shiver? 5 Common Reasons
There are a variety of reasons why your Chihuahua might be shaking. Understanding these reasons can help you determine if the shaking is normal or if it warrants further investigation. Here are five common reasons behind Chihuahua shaking:
1. Feeling Cold
Chihuahuas, with their small size, low body weight, and thin coats, are highly susceptible to feeling cold. Their bodies lose heat more rapidly than larger breeds, and their thin fur offers minimal insulation against cold temperatures. If your Chihuahua is shaking or shivering, especially in cooler environments, the most likely reason is simply that they are trying to warm up and regulate their body temperature.
Look for other signs that your Chihuahua might be cold. These can include:
- Seeking out warm places like blankets, sunny spots, or your lap.
- Curling up into a tight ball to conserve heat.
- Reduced activity levels, becoming less playful and more lethargic.
- Pale or even bluish gums in severe cases of cold exposure.
If you observe these signs alongside shaking, try to warm your Chihuahua up. Provide a cozy sweater, a warm blanket, or move them to a warmer location. If the shaking subsides after warming up, then cold sensitivity was likely the cause.
2. Fear and Anxiety
Chihuahuas have a reputation for being nervous and anxious dogs. They can be easily startled or overwhelmed by unfamiliar situations, loud noises, strangers, or changes in their routine. This breed’s sensitive nature makes them prone to anxiety, and shaking is a common physical manifestation of fear and stress in Chihuahuas.
If your Chihuahua is shaking and also exhibiting other signs of fear or anxiety, such as:
- Cowering or trying to hide.
- Tucked tail.
- Whining or whimpering.
- Panting or increased respiration (when not hot).
- Trembling lips or ears held back.
- Avoiding eye contact.
Then it’s highly likely that your Chihuahua is shaking due to feeling stressed or anxious. Identify the potential source of their fear and try to remove them from the stressful situation if possible. Create a calm and safe environment for them to relax.
3. Excitement and Over-Energy
Not all shaking in Chihuahuas is negative! Believe it or not, many Chihuahuas will shake when they are extremely excited or happy. This type of shaking is a release of pent-up energy and enthusiasm. It’s often accompanied by other positive signs of excitement, such as:
- Vigorous tail wagging.
- Jumping up and down or “zoomies” (running around energetically).
- Playful barking or yipping.
- Ears forward and alert posture.
- Eagerness to play or interact.
If your Chihuahua is shaking in a context of play, greeting you, or anticipating a fun activity like going for a walk, the shaking is likely due to excitement. In these cases, the shaking is perfectly normal and will usually subside as their energy levels normalize.
4. Low Blood Sugar (Hypoglycemia)
Chihuahuas are predisposed to hypoglycemia, a condition where their blood sugar levels drop too low. This is particularly common in Chihuahua puppies and toy breeds due to their small size and rapid metabolism. They have limited glycogen stores (stored glucose) in their liver, making them more vulnerable to blood sugar dips, especially if they go too long without eating.
When a Chihuahua’s blood sugar drops, their body doesn’t have enough fuel to function properly. Hypoglycemia can manifest with a range of symptoms, including:
- Shaking or trembling.
- Lethargy, weakness, or drowsiness.
- Confusion or disorientation.
- Unsteady gait or stumbling.
- Pale gums.
- In severe cases, seizures or loss of consciousness.
Hypoglycemia is a serious condition that requires prompt attention. If you suspect your Chihuahua is hypoglycemic, especially if they are exhibiting lethargy or weakness along with shaking, it’s crucial to seek veterinary care immediately.
A veterinarian can perform a blood glucose test to confirm hypoglycemia and provide appropriate treatment. Treatment typically involves administering glucose, either orally (like honey or corn syrup on the gums, only under vet direction) or intravenously. Long-term management may include dietary adjustments and frequent, small meals to prevent future episodes.
5. Underlying Health Issues
In some instances, shaking in Chihuahuas can be a symptom of an underlying medical condition. While less common than the other reasons listed, it’s important to consider health issues, especially if the shaking is new, persistent, or accompanied by other symptoms. Potential health issues that could cause shaking include:
- Pain: Pain from arthritis, injuries, or internal issues can cause shaking.
- Neurological problems: Conditions affecting the nervous system can lead to tremors and shaking.
- Generalized Tremor Syndrome (GTS): Also known as “Little White Shaker Syndrome” (though it can affect dogs of all colors), GTS is an idiopathic condition that causes full-body tremors.
- Kidney disease or liver disease: These conditions can sometimes cause tremors due to metabolic imbalances.
- Canine Distemper: A serious viral disease that can cause neurological symptoms including tremors and seizures. (Vaccination is crucial to prevent this).
- Certain toxins or medications: Exposure to toxins or side effects of some medications can induce shaking.
If your Chihuahua’s shaking is accompanied by other concerning symptoms such as:
- Limping or signs of pain.
- Vomiting or diarrhea.
- Loss of appetite or weight loss.
- Increased thirst or urination.
- Lethargy or weakness.
- Coughing or difficulty breathing.
- Seizures or neurological signs.
It is essential to consult with your veterinarian promptly to rule out any serious health concerns and get a proper diagnosis and treatment plan.
Why Do Chihuahuas Shake When They Sleep?
It’s not uncommon for Chihuahua owners to notice their dogs shaking or twitching while they are sleeping. This is generally a normal phenomenon and usually not a cause for concern.
This sleep shaking is believed to be related to the active dream state, also known as REM (Rapid Eye Movement) sleep. Just like humans, dogs, including Chihuahuas, go through different sleep cycles, including periods of deep sleep and REM sleep where dreaming occurs.
During REM sleep, the brain is highly active, processing information and experiences from the day. While the body is mostly paralyzed to prevent acting out dreams, some muscle twitching and movements, including shaking, can occur involuntarily as signals are sent from the brain to the muscles.
Think of it like when humans might talk or move in their sleep. Similarly, a Chihuahua might twitch their paws, whine softly, or even shake or tremble during a vivid dream. It’s thought they might be dreaming about running, playing, or even experiencing mild stress in their dream world, leading to these physical manifestations.
While occasional shaking or twitching during sleep is normal, it’s still wise to monitor your Chihuahua’s overall health and behavior. If you notice significant changes in their sleep patterns, if the shaking seems excessive or violent, or if they seem distressed even when waking up, it’s worth consulting with your veterinarian to rule out any potential underlying issues.
How To Help Your Chihuahua Stop Shaking (When Necessary)
The approach to stopping your Chihuahua’s shaking depends entirely on the underlying cause. If you suspect hypoglycemia or a medical condition, veterinary intervention is paramount. However, if the shaking is related to anxiety, stress, or cold, you can take steps to help calm and comfort your Chihuahua.
Create a Safe and Cozy Space
Providing your Chihuahua with a secure and comfortable retreat is crucial for managing anxiety-related shaking. A “safe space” can be a crate, a dog bed in a quiet corner, or even a designated area under a piece of furniture. The key is that it’s a place where your Chihuahua feels protected and can relax without being disturbed.
Consider these elements when creating a safe space:
- Location: Choose a quiet area of your home, away from high-traffic zones, loud noises, and excessive activity.
- Comfort: Make it cozy with soft bedding, blankets, and perhaps a favorite toy.
- Den-like feel: Some Chihuahuas prefer enclosed spaces like crates, which provide a sense of security. Others prefer open beds or cushions. Observe your dog’s preferences.
- Pheromone Diffusers: Consider using dog-appeasing pheromone diffusers or sprays near their safe space. These can emit calming scents that promote feelings of security.
Encourage your Chihuahua to use their safe space as a positive retreat, not as a punishment. Make it a comfortable and inviting haven where they can go to de-stress.
Utilize Calming Techniques
Several calming techniques can help reduce anxiety and stress-induced shaking in Chihuahuas:
- Calming Music: Playing soft, calming music, particularly classical music or music specifically designed for dogs, can have a soothing effect and reduce anxiety.
- Pheromone Therapy: As mentioned, pheromone sprays and diffusers can mimic natural dog appeasing pheromones, creating a sense of calm.
- Calming Wraps: “Thundershirts” or similar anxiety wraps apply gentle, constant pressure, which can have a comforting effect for some dogs.
- Herbal Remedies and CBD Oil: Certain herbal remedies like chamomile or valerian, and CBD oil specifically formulated for pets, may have calming properties. Always consult with your veterinarian before using CBD oil or herbal remedies to ensure safety and appropriate dosage.
- Gentle Massage: Slow, gentle stroking and massage can help relax tense muscles and reduce anxiety.
- Consistent Routine: Chihuahuas thrive on routine. Predictable feeding times, walks, playtime, and sleep schedules can reduce anxiety by providing a sense of security and predictability.
Ensure Adequate Exercise and Playtime
While Chihuahuas are small, they still need regular exercise and mental stimulation. Sufficient physical activity can help burn off excess energy and reduce anxiety levels. Playtime is also crucial for mental enrichment and bonding.
- Daily Walks: Even short daily walks are beneficial for physical and mental well-being.
- Indoor Play: Engage in indoor games like fetch, hide-and-seek, or puzzle toys, especially on days when outdoor walks aren’t feasible.
- Training: Positive reinforcement training is a great way to mentally stimulate your Chihuahua and build confidence.
- Interactive Toys: Provide puzzle toys or treat-dispensing toys to keep them mentally engaged and prevent boredom.
Adequate exercise and playtime can contribute to a calmer, more balanced Chihuahua, reducing the likelihood of shaking due to pent-up energy or anxiety.
My Chihuahua Still Won’t Stop Shaking – When to See a Vet
If your Chihuahua’s shaking is persistent, frequent, or accompanied by other concerning symptoms, it’s crucial to seek veterinary attention. Even if you’ve tried calming techniques and warming them up, if the shaking continues, it’s important to rule out any underlying medical conditions.
Don’t hesitate to schedule a veterinary appointment if:
- The shaking is new and you can’t identify an obvious trigger like cold or anxiety.
- The shaking is frequent or occurs daily.
- The shaking is accompanied by other symptoms like lethargy, vomiting, diarrhea, coughing, loss of appetite, or changes in urination/thirst.
- You suspect hypoglycemia, especially if your Chihuahua is weak or lethargic.
- You are simply concerned and want professional reassurance.
Your veterinarian can perform a thorough physical examination, run diagnostic tests if needed (like blood glucose tests or bloodwork), and provide an accurate diagnosis and appropriate treatment plan. Early veterinary intervention can be crucial for managing underlying health conditions and ensuring your Chihuahua’s well-being.
Bottom Line: Understanding Why Chihuahuas Shake
Chihuahua shaking is a common behavior with a range of potential causes. While some reasons, like feeling cold, excitement, or dreaming, are perfectly normal, others, such as anxiety, hypoglycemia, or underlying health issues, require attention.
By carefully observing your Chihuahua’s behavior, considering the context of their shaking, and being aware of any accompanying symptoms, you can better understand why your Chihuahua is shaking. When in doubt, or if the shaking is persistent or concerning, always consult with your veterinarian.
