Chihuahuas are renowned not only for their diminutive size but also for their propensity to shiver. But what’s behind the quivering? For those new to Chihuahua ownership, this behavior can be disconcerting. However, there’s no need to fret; Chihuahuas shake for various reasons, including their high metabolisms, excess energy, and difficulty regulating their body temperature.

Let’s delve into the causes of these petite, sassy canines’ inclination to tremble.

Why Do Chihuahuas Shake?

Chihuahuas often shake due to a combination of genetics and their tendency toward nervous temperaments. Additionally, they are susceptible to various health issues, such as tremor disorders, low blood sugar, and heightened sensitivity to cold, all of which can trigger shaking.

Let’s take a closer look at the factors contributing to these charming micro-divas’ tremors.

15 Common Reasons for Chihuahua Shaking:

1. Blood Sugar: Shaking can result from hypoglycemia or low blood sugar, primarily affecting toy and small-breed dogs, including young puppies. A sudden shift in blood chemistry prompts shaking as dogs strive to stabilize their sugar levels. Regular feeding schedules with multiple small meals and a balanced diet can help prevent this.
2. Temperature Regulation: Chihuahuas’ petite size makes them susceptible to both hot and cold temperatures. Shaking is a natural mechanism dogs use to regulate their body temperature. When they shiver, it’s a sign they’re feeling cold, and their bodies are generating heat to warm up. Provide a warm blanket or keep them indoors during chilly weather.
3. Anxiety and Fear (Genetic Predisposition): Chihuahuas are prone to psychological issues and tend to be more sensitive than other breeds. Genetic predisposition, coupled with insufficient socialization during puppyhood, can lead to anxious behaviors.
4. Kidney Disease: Shaking might indicate kidney disease, a common cause of tremors in small dogs. This condition can go unnoticed until severe symptoms manifest, including weight loss, increased thirst, frequent urination, vomiting, and sometimes involuntary urination during sleep.
5. Excitement: Chihuahuas are highly excitable dogs, and shaking can occur when they’re enthusiastic about various activities, from seeing their owner to going for a walk.
6. Generalized Tremor Syndrome: A genetic disorder causing dogs to shake all over, Generalized Tremor Syndrome (GTS) primarily impacts toy white terriers but can affect dogs of various sizes and colors. It’s challenging to diagnose and is often mistaken for other conditions like hypothyroidism or epilepsy.
7. Separation Anxiety & Noise Phobia: Separation anxiety can induce shaking, especially in Chihuahuas, which rely on their owners for comfort and companionship. Noise phobia, triggered by loud sounds like thunder or fireworks, can also lead to shaking.
8. Nausea: Illness-induced nausea can prompt shaking in Chihuahuas. This can result from various factors, including parasites, food allergies, or food sensitivities. Identifying the cause of nausea is crucial for proper treatment.
9. Distemper: Distemper, a viral disease, can lead to shaking, among other symptoms. If symptoms like fever, runny nose, vomiting, and diarrhea appear, consult a vet immediately.
10. Inflammatory Brain Diseases: Conditions like meningitis and encephalitis can cause shaking by causing brain inflammation, which leads to discomfort.
11. Seizures (Hydrocephalus, Liver Shunts, Epilepsy, etc.): Chihuahuas are prone to seizures, often accompanied by shaking, and may be linked to conditions like hydrocephalus, liver shunts, or epilepsy.
12. Poisoning: Ingesting toxic substances such as chocolate, alcohol, or certain chemicals can result in shaking, seizures, and even death in dogs. Swift veterinary attention is vital.
13. Internal Injury & Pain: Pain, discomfort, or injury can cause shaking. Small terrier breeds are particularly sensitive to pain.
14. Old Age: As Chihuahuas age, they may experience shaking, which typically begins around 10 years old. It’s a normal part of aging.
15. Ear Infection (Head Shaking): Ear infections can lead to head shaking as dogs try to alleviate pain and discomfort. Redness, swelling, discharge, and an unpleasant odor may accompany ear infections.

Why Is My Chihuahua Shaking More Than Usual?

Chihuahuas, with their high metabolism, can become excited or overstimulated, leading to shaking. Frequent shaking in these dogs, especially when it’s not due to excitement or anxiety, should prompt further investigation, as it could signal an underlying issue.

Common Shaking Myths:

1. There’s something wrong: Shaking is often natural for Chihuahuas, particularly when they’re excited, anxious, or full of energy. It’s generally not a cause for concern and won’t lead to long-term problems.
2. It’s uncommon: Shaking is common in Chihuahuas due to their high metabolism. However, excessive or persistent shaking unrelated to excitement or anxiety may warrant attention.

In conclusion, understanding the reasons behind Chihuahua shaking can help you provide appropriate care and ensure your furry friend’s well-being. If you notice unusual or persistent shaking, consulting a veterinarian is advisable to rule out any underlying health issues.
