Why Do Dogs Shiver? Other Causes Besides Cold

As winter approaches, the chill of the season inevitably affects both humans and pets, including their daily activities like walks on a leash. Many pet owners notice their dogs shivering, whether they are out for a walk or simply relaxing at home. The first assumption is often that the dog is cold, which leads owners to dress their dogs in warm clothing before taking them out. However, shivering can occur for reasons other than cold. Below, we'll explore several possible causes of shivering in dogs.

1. Shivering Due to Fear Just like humans, dogs can shiver when they experience strong emotions. Fear is a common trigger for shivering in dogs. For instance, during a walk, if a large dog on a leash encounters a small dog, the small dog may bark and act aggressively, but the owner can often tell from the trembling leash that the small dog is actually scared. Similarly, if an owner threatens the dog with a stick or other object, the dog may instinctively retreat and start shaking uncontrollably. This type of shivering is a natural response to perceived threats. 2. Shivering Caused by Poisoning Shivering may also be a sign that a dog has ingested something toxic, such as morning glory seeds, castor beans, or certain chemicals. These substances could be in the home or may have been consumed while the dog was out on a walk. In contrast to fear-induced shivering, poisoning typically presents with other symptoms, such as vomiting or lethargy. If you suspect poisoning, it's essential to seek veterinary care immediately. Pet owners should be cautious and keep their dogs from eating random things during walks by keeping them on a leash. 3. Illness as a Possible Cause of Shivering Dogs rarely shiver without a reason. Larger breeds, such as Golden Retrievers, often experience shaking due to joint pain, which can be caused by conditions like hip dysplasia or avascular necrosis (bone death). Regular exercise on a leash can help strengthen a dog's body, and ensuring they get enough calcium is important for bone health. Additionally, when training with a leash, owners should watch out for signs that the dog might be in pain due to an injury or other underlying health issue. 4. Normal Shivering from Cold Of course, shivering is also a natural response to cold temperatures. In such cases, mild shivering or leg cramps are normal. During winter, it's a good idea to reduce evening walks and opt for daytime walks when the sun is out. To keep your dog comfortable, you can prepare a warm bed or use a dog coat to help them stay warm. If the shivering is severe or persistent, and the dog cannot seem to control it, a visit to the vet is recommended to rule out any underlying issues.

In conclusion, while cold weather can certainly lead to shivering in dogs, it is important for owners to be aware of other potential causes. Regular vet checkups, proper training, and keeping your dog on a leash during walks can help prevent and address these issues effectively.
