Why do dogs shake?

There is no one single reason that can explain why dogs shake. Canine body language is incredibly complex and the same behavior, depending on context, may differ largely in meaning.

If you want to know why your dog shakes, you need to also consider your dog’s general behavior, overall body language and environment. It’s also important to identify whether these jolts are sudden or recurring, for example, do they only happen when your dog is wet or all the time?

Why do dogs shake off?

You’ve probably noticed that your dog shakes after a bath or swim, which is normal dog after bath behavior. Dogs shake when they get wet because, by reproducing this movement quickly and intensely, they can eliminate water that has accumulated on the mantle and on the skin. Shaking acts as a natural drying method for dogs, helping them avoid cold and discomfort.

However, if you notice that your dog isn’t managing to dry itself fully by shaking, we suggest that you help with a towel. The accumulation of moisture on a dog’s skin and hair favors the proliferation of pathogenic microorganisms and this needs to be avoided.

Dog shaking off stress

Many dog lovers wonder why their dogs are shaking even when completely dry. The main cause for this type of dog shaking is due to stress or boredom.

Boredom and stress in dogs are commonly associated with a sedentary routine and/or a negative environment. When dogs do not receive adequate physical and mental stimulation or are not offered an enriched environment, they tend to find other ways to relieve accumulated tension and energy.

Shaking in dogs is one of the most common symptoms of stress in dogs. A dog shaking can help reduce muscle tension, offering it a sense of relief. In the event that this boring and/or stressful routine continues, a dog may suffer from additional behavioral problems, such as destructiveness.

In more serious cases, when stress in dogs becomes chronic, a dog can even present stereotypies. The stereotypies are characterized by the incessant repetition of certain behaviors or actions, such as shaking. Therefore, if you notice that your dog is shaking excessively, we recommend that you consult an ethologist or veterinarian. For more, we recommend taking a look at our article where we discuss everything you need to know about compulsive behavior in dogs.

Why do dogs shake when they wake up?

When getting up or waking up, it’s normal for dogs to shake. This shaking helps wake a dog up, preparing its body for the new day. It’s also very common for dogs to shake when they leave the home, especially during the winter. In this case, shaking helps alleviate the strange sensation generated by a sudden change in temperature. This is especially common when a dog leaves a heated environment for a cold one.

For this reason, it’s very important to remember that not only do dogs feel the cold, but low temperatures can also seriously damage a dog’s health. In winter, dogs are more vulnerable to suffering from colds and the flu. For this reason, it is essential to protect your dog from the cold. For more, read about colds in dogs.

Dog shaking and parasites

If your dog tends to spend a lot of time outside, it’s very likely that it will come into contact with dirt, twigs, leaves, dirt and grass. In this case, it’s normal that a dog will shake to remove leftover residues from the coat and skin, preventing these objects from causing itching, discomfort or disease.

Is your dog shaking and scratching constantly or excessively? In this case, your dog may be suffering from fleas, mites or ticks. The bites of these ectoparasites can cause discomfort and itching, which could explain why a dog is shaking excessively. Dogs need to follow an appropriate deworming schedule strictly in order to prevent parasite infestation.

In summer, it’s very common to see dogs shake to scare off mosquitoes and other insects. In addition to being incredibly annoying, there are several diseases that mosquitoes can transmit to dogs, such as canine leishmaniasis and heartworm (also known as "heartworm"). For more about these, we suggest taking a look at our article where we list the most common mosquito-borne diseases in dogs.
