Why does my Chihuahua shake so much?

As the world’s smallest dog, the Chihuahua gets cold very easily. Specifically, only in the warmest of weather are they unlikely to shake. Shaking allows the body to keep blood flowing, thereby preventing hypothermia. It is not dangerous for your Chihuahua to shake when they are cold, and a cozy blanket in their basket should do the trick.

Other reasons for shaking include nervousness and fear, and in more serious situations pain, low blood sugar and Addison’s disease. It is important to note that shaking as a result of a medical concern is only one of many other symptoms. Nevertheless, always consult with your veterinarian if your Chihuahua’s shaking is more aggressive or pronounced from their “normal” shaking.

Chihuahua common health problems

Let’s discuss some common health concerns of the Chihuahua. To note, this list is not stagnant and Chihuahuas may additionally suffer from any health conditions that are common to their larger counterparts. 

Low blood sugar

Typically characterized by weakness and a loss of coordination. Additionally, seeking immediate veterinary care is imperative. Maintaining a regular feeding schedule and prescription medication is key to treating this condition. 

Dislocated kneecap

This condition can cause pain and discomfort. Speak with your veterinarian about treatment options for your pet. 

Tracheal Collapse

Tracheal Collapse varies in seriousness and is diagnosed via an X-Ray. In serious cases this condition is treated with bronchodilators and corticosteroids to prevent inflammation. This condition normally worsens as your Chihuahua ages. 


Similarly referred to as “fluid on the brain”, this serious life-threatening condition often results in a shorter life span. 


Characterized by seizures which may vary in intensity and duration. The treatment for epilepsy may be lifelong and therefore requires commitment from the pet parent. 

Heart Disease

Regular veterinary appointments will identify whether your Chihuahua has heart disease. When diagnosed early, this condition is treatable. Treatment usually involves life-long medication.

Tooth and Gum Disease

Speak with your veterinarian about scheduling regular dental cleanings. 

As a pet parent, you are never guaranteed that your Chihuahua will suffer from any health concern, whereas in other instances they may have multiple health concerns. This is especially true for our senior friends. It is important to note that the Chihuahua is a resilient dog with a fighting spirit, and under the right veterinary care they can live full and happy lives. Start by feeding the right food from the start and by visiting your veterinarian for check-ups.
