Dogs experience emotions and express them in ways that closely resemble human behaviors. For instance, they might "smile" when they're happy or give you those unmistakable "puppy dog eyes" when they're sad or seeking attention. But what does it mean when they shake?
There are many reasons a dog may tremble, and some cases are simpler than others to understand.
"Shaking in dogs can occur for a variety of reasons, and understanding the context is crucial in determining whether it's a cause for concern," veterinary surgeon Nick Horniman told Newsweek.
Horniman, the founder of the online pet pharmacy MyPetsVet, reassures that shaking is "entirely harmless" in many cases.
"It may simply be a reaction to excitement, cold temperatures, or being wet after a bath. However, it can sometimes signal an underlying issue that requires attention," he said.
Anxiety or Fear
The American Kennel Club (AKC) states that the most common causes of dog anxiety are fear, separation and aging.
"Dogs often tremble when they feel anxious or stressed. Situations such as fireworks, thunderstorms, or even visits to the vet can trigger this response," Horniman said.
Owners can comfort their dogs and reduce anxiety by creating a calm environment or using aids like pheromone diffusers.
Cold Weather
"Shaking can also be a sign that your dog is cold, especially for breeds with short coats, like Greyhounds," Horniman said. "In these cases, providing a well-fitted coat or blanket can make a big difference."
Health Problems
In some cases, shaking may indicate pain or discomfort caused by a medical condition such as arthritis, an injury, or an underlying illness.
"If the shaking persists, occurs alongside other symptoms like lethargy or vomiting, or appears to happen without an obvious trigger, it's important to seek veterinary advice promptly," Horniman said. "A thorough examination can help identify the cause and ensure your dog receives the care they need to feel comfortable and happy again."
Knowing The Difference Between Shaking During Sleep And A Seizure
Like humans, dogs tend to dream, which can sometimes be associated with twitching during sleep—this is normal. Dr. Liza Cahn, a veterinarian at Embrace Pet Insurance in Cleveland, Ohio, has highlighted signs of abnormal behavior.
She told Newsweek: "It's common to see slow, rhythmic paddling of the limbs and hear vocalizations during sleep that resemble whining."
Seizures, on the other hand, are more common in awake dogs.
"Symptoms of seizures include a stiff, rigid body, labored breathing, loss of consciousness, urination or defecation, foaming at the mouth and vomiting. This is generally followed by a post-ictal phase in which a dog may appear confused or disoriented," Cahn said.
