‘Why does my Chihuahua shake’ is a common question that many Chihuahua dog parents will ask at one point. There is typically a reason why your Chihuahua will shake or shiver, so it’s important to pay attention. Here are both physiological and emotional reasons why your Chihuahua may tremble, shake, and shiver, as well as solutions for each.

Your Chihuahua may shake because of their high metabolism.

Chihuahuas are a tiny ball of unstoppable energy. Even while resting, the Chihuahua’s metabolism is burning calories at almost triple the rate of a mid-size dog. Since Chihuahuas have these naturally high metabolisms, they may shiver when they are excited or anxious. The high metabolism also affects a Chihuahua’s ability to regulate their own body temperature. When an animal has a naturally high metabolism, they burn off their body heat at a quicker rate. So they will feel cold a lot earlier than you might.

Because your Chihuahua has this high metabolism, they are more prone to be sensitive to cold weather. They are one of the smallest dog breeds out there, and combine that with their turbo metabolism and lack of body fat creates a recipe for coldness. Your pup may be shaking and trembling as a way to create heat back into their bodies. My Chiweenie (Chihuahua mix) starts to shake when the weather starts to get colder outside, way before my other dog gets cold, so I have to be cognizant of this.

In addition to being aware that your Chihuahua may be getting cold quickly, you can also try to dress them more warmly, so they are prepared. Especially in the Fall and Winter seasons. You may think your Chihuahua is fine in 50 degree weather, but that may not be the case. Definitely keep an eye open on your dog’s movements. Your Chihuahua may have cold paws, a cold belly, or may be trembling because they just feel too chilly. There are even boots you can try, so their cold paws can stay warmer and dryer.

Your Chihuahua may shiver because they are frightened, scared, anxious, or excited.

Your Chihuahua may express their emotions in the form of shaking, shivering, or trembling. So when they are shaking, it’s a side effect of the emotion they are feeling at the moment. This is another area where you need to be aware of your dog’s environment. For example, if your Chihuahua is shaking because they are nervous around a big dog in the dog park, it’s a good idea to move them away from the situation. The last thing you want is your Chihuahua to attack a bigger dog that could resort in your dog getting hurt way worse. By understanding your dog’s body language, you will be able to anticipate potentially dangerous situations and remove your dog from it.

Chihuahuas need to be constantly socialized, so they become adjusted to being around different breeds and sizes of dogs. This socialization should start from when they are puppies and be constant throughout their lives. They are less likely to shake when they are comfortable in situations. These dogs can also shake when they are left alone or neglected, so make sure your dog is getting enough love.

Why Does My Chihuahua Shake, Tremble, and Shiver

Always make sure with your veterinarian your Chihuahua isn’t shaking because of a serious condition.

You should always discuss with your veterinarian your Chihuahua’s behavior, so it’s important to let them know if they are shaking. There are additional medical conditions that are more serious that may prompt their shivering. For example, they could have kidney failure, an ear infection, allergies, or some type of trauma. They may have ingested something poisonous to them that triggered the shaking. Always consult your veterinarian to rule out any condition that needs prompt attention and care.
