Why is my dog shaking? Common reasons for shivering and trembling

Seeing your dog shake or shiver can be worrying, but it isn't always a cause for alarm. Dogs tremble for a wide variety of reasons, from simple excitement to physical pain or feeling a bit chilly, according to Dog Shivering and Trembling: Causes and Treatments.

Is my dog shaking because they are cold?

Shivering is a natural way for a dog's body to generate heat when their core temperature drops. Small breeds, dogs with thin coats (like Greyhounds), and senior dogs are much more sensitive to the cold and may start shaking even in mild temperatures. If the shaking stops once you wrap them in a blanket or bring them inside, they were likely just chilly.

Can excitement or "happy shakes" cause trembling?

Yes, many dogs physically tremble when they are extremely excited or anticipating something they love. This is often seen when you come home from work, right before a walk, or when they see a favorite toy. This type of shaking is normal and usually stops once the dog calms down or the activity begins.

Is my dog shaking because they are in pain or sick?

Shivering is a very common, subtle sign of physical discomfort or hidden pain in dogs. As noted in 7 Common Worries of Pet Owners, pets often can't vocalize when something is wrong, so they use physical cues like trembling to show they aren't feeling well. If your dog is shaking while resting, or if the trembling is concentrated in their hind legs, it could indicate issues like arthritis, back pain, or an upset stomach.

Could it be a sign of anxiety or fear?

Dogs often shake when they are feeling stressed, anxious, or afraid of their environment. Common triggers include thunderstorms, fireworks, or visits to the vet. This type of shaking is usually accompanied by other body language cues like panting, pacing, or tucking their tail between their legs.

When should I call the vet about my dog's shaking?

You should contact your veterinarian if the shaking is persistent, violent, or accompanied by other concerning symptoms. While some shaking is normal, you should seek professional advice if you notice:

• Shaking that doesn't stop when the dog is warmed or calmed.
• Lethargy or weakness, or a refusal to eat.
• Vomiting, diarrhea, or stumbling.
• Signs of a seizure, such as muscle rigidity or loss of consciousness.
