Why Do Chihuahuas Shake?

Whether it is because of their small size, genetic makeup, or anxieties brought on by separation from their owners or other environmental stimuli, understanding what causes this behavior in our canine companions can help us better care for them and make sure that any shakes aren’t due to medical issues.

In this blog post, we will explore some popular explanations behind why do Chihuahuas shake?—from those who believe they are born with inherent jitters to others who say that certain noises spark fear in these pups—to better understand this behavior and provide possible solutions.

Why Do Chihuahuas Shake?

The first theory as to why Chihuahuas shake is due to their small size. Due to their diminutive stature, these pups have a higher surface area-to-body weight ratio, which means they can easily become cold. As such, many believe that the shakes are simply an involuntary reaction related to temperature regulation — it’s just their way of trying to keep warm!

The second explanation for chihuahua shivering is that it is a part of their genetic makeup. Some experts say that the breed has been selectively bred over time to produce dogs with an innate jittery, trembling behavior — and this trait has been passed down through generations.

A third potential explanation for why chihuahuas shake is related to anxiety. Because these dogs can be prone to separation anxiety, they may become anxious when their owners are away or in new situations and start shaking as a result. Loud noises and unfamiliar environments can also trigger this reaction in some of these pups.

Finally, some believe that Chihuahuas shake due to medical issues. If your pup is shaking and there doesn’t appear to be a logical explanation, it’s always best to consult a veterinarian in order to rule out any possible health conditions that might be causing the tremors.

Is It Normal for Chihuahuas to Shake?

In general, shaking and trembling can be normal for Chihuahuas. As we discussed above, there are many potential explanations for why do Chihuahuas shake? — from cold temperatures to genetic predisposition to anxiety — so it’s important to recognize when a pup is shivering in order to properly address the issue.

It is important to remember that shaking and trembling can also be signs of distress, especially if they persist or worsen. If you notice your Chihuahua is shaking more frequently than normal, it’s best to visit a veterinarian to rule out any potential medical issues.

Medical Conditions that Cause Chihuahuas to Shake

Chihuahuas are small, lively dogs that often experience stress and anxiety due to their size. However, sometimes Chihuahuas shake because of a medical condition. Here are some conditions that might cause your Chihuahua to shake:

1. Anemia:

Anemia is caused by a lack of red blood cells or hemoglobin in the blood. When there is not enough oxygen being delivered to the body, it can cause a Chihuahua to shake or tremble.

2. Hypoglycemia:

Chihuahuas with hypoglycemia have low levels of glucose (sugar) in their blood. This can be caused by a lack of food or if their last meal was too small. The tremors that accompany hypoglycemia can be very subtle and may require a blood test to confirm the diagnosis.

3. Hypothermia:

Chihuahuas are particularly prone to hypothermia due to their tiny size and thin coats. If your Chihuahua is exposed to cold temperatures or gets wet, they can quickly become chilled and begin shaking. Your Chihuahua must remain warm and dry in the colder months.

4. Poisoning:

Chihuahuas are at risk of accidental poisoning due to their curiosity and small size. If you think your Chihuahua may have ingested something toxic, take them to the vet right away. Common signs of poisoning include excessive shaking and trembling.

5. Seizures:

Seizures are caused by abnormal electrical activity in the brain, which can cause a Chihuahua to shake uncontrollably. If your Chihuahua has any kind of seizure, it’s important to take them to the vet for further evaluation.

If your Chihuahua is shaking and you are unsure of why, contact your veterinarian. Your vet can help diagnose any medical issues that may be causing the trembling and provide treatment to keep your Chihuahua happy and healthy.

How to Help a Chihuahua Stop Shaking

If your Chihuahua is shaking, it can be a sign of fear or anxiety. It may also be a symptom of some medical issue like hypoglycemia, cold temperatures, dehydration, or pain.

In order to help your Chihuahua stop shaking, start by determining the cause. If it is due to fear or anxiety, start by keeping your Chihuahua away from situations that trigger the shaking. This could include loud noises or crowded places. If it is due to a medical issue, then you should consult with your veterinarian for proper diagnosis and treatment.

Once the cause of the shaking has been determined, there are some things you can do to help your Chihuahua stop shaking. You can provide a safe environment for your pet by reducing loud noises and providing a comfortable place for them to rest. Additionally, you should check their diet to ensure they are getting the proper nutrition as well as making sure they get plenty of exercise and playtime every day.

You can also help reduce stress and anxiety in your Chihuahua by providing positive reinforcement training. This will help to build a trusting relationship between you and your pet as well as teaching them how to cope with their fears in more appropriate ways than shaking. Additionally, there are natural remedies like chamomile tea or lavender oil which can be used to reduce stress in your pet.

Finally, if all of these methods do not help to stop your Chihuahua’s shaking, then it is important to take them to the veterinarian for a checkup and further evaluation. Your vet can provide medical treatment and advice on how best to help your pet cope with their fear or anxiety.

With a bit of patience and understanding, you can help your Chihuahua stop shaking. With the right care and support, your pet will be on the road to better health in no time.
