Shaking (trembling or shivering) can be a symptom of several possible problems such as a response to pain and discomfort that results from an illness or injury, a response to emotional distress, anxiety or a symptom of certain types of seizure.
The presence of fever is an important symptom, when a dog has a fever you must take the dog to a veterinarian before the problem gets worse, so the quicker you can get a diagnosis, the easier and faster your dog will be better.
So once diagnosed, your veterinarian will prescribe a medication for your dog’s specific needs: every dog needs the proper dosage and treatment that will work best for it.
Hypoglycemia (low blood sugar) is very often a cause of shaking. It occurs when a pet hasn’t eaten for a long period of time and it can also be associated with weakness and vomiting.
Elevated body temperature caused by an infection or an illness can produce shivering and trembling.
If shaking is associated with lethargy and your dog is restless, it don’t eat or drink the situation is more serious and only a good vet can give the right advice; many serious disease could go undetected such as Addison’s Disease (Hypoadrenocorticism) which is the insufficient production of essential adrenal hormones by the adrenal gland.
