Common Causes and Treatments

Knowing exactly what has caused your dog’s shaking may need to be determined by a vet! It is still best to go to a registered veterinarian for an official diagnosis. The common causes and treatments, however, are listed below. 


Canine Distemper is a virus that is related to the measle virus, and it most often occurs in unvaccinated puppies. It can affect the eyes, nose, teeth, and genitals. The virus usually presents itself with a fever and discharge from the eyes and nose. Other symptoms may include coughing, a runny tummy, and the skin on the nose hardening. Treatment includes Antibiotics, keeping the nose and eyes clean, and lots of fluids to keep your dog hydrated. Contact your vet immediately if you pick up on any of these symptoms. It would be wise not to come in close contact with your animal and ensure you are guarded with durable clothing!

Steroid Responsive Tremor Syndrome (Also Known as Generalised Tremor Syndrome or GTS)

Generalized Tremor Syndrome first occurred in small white dogs, but it can happen to dogs of any breed, size, and color. It is still unknown what causes GTS. It often appears between 9 months to 2 years of age. Treatment mostly consists of medicine such as Prednisone, and results can be seen in as little as one week after treatment has begun.


Nausea can be caused by anything from motion sickness or medication to poisoning. Other diseases can cause nausea as well. Other, more serious symptoms apart from shaking include swallowing more or having more saliva than usual, hiding, excessive yawning, and vomiting. These symptoms are common if your dog has been poisoned. Also, think back to where your dog has been and if they have had any recent access to any hazardous material! If you suspect poisoning, please contact your vet immediately.

Pain From Old Age

It is true that some dogs develop tremors in their hind legs or sometimes even their front legs. However, it cannot be assumed that it is caused by old age. Sometimes it is due to pain, and you should always consult your vet for a possible diagnosis.

Being Poisoned 

What might seem harmless to humans can be very toxic for dogs, for example, chocolate and cigarettes. Other products like household cleaners and pesticides can be very harmful as well. Symptoms of poisoning can vary from tremors, drooling, vomiting, runny tummy, and seizures. In the event of poisoning or suspected poison, contact your vet or Animal Poison Control Centre.


Epilepsy can cause seizures in dogs and can look a lot like shaking. Look for other symptoms like chewing of the tongue or stiffening of the muscles. A dog having a seizure will also not be aware of his surroundings. Your vet can prescribe certain medications to help with treatment.


Some dogs will shake with excitement to see their owner when they come home. They may even bark or pee a little, which is normal. Training your dog to sit before you greet them and keeping the greeting short may help with this. However, some dogs may get over-excited and if this is not treated properly, it could do your dog harm, as there is a chance they could develop anxiety! Ensure that you treat your over-excited pup as soon as you see a problem arising!

When to See a Vet

Less Common Causes of Shaking

Some of the less common reasons for your dog’s shaking might include brain tumors, diseases, eating food that is cold, or depression.
