What Causes Dogs With Epilepsy?
Dogs with epilepsy, also known as seizures, can be defined as "repeated involuntary contractions of muscles with changes from sensory, cognitive to motor behavior". . Seizures occur due to sudden and excessive discharge of a group of neurons in the brain.
There are two types of seizures, a localized epilepsy affecting one part of the body and a generalized epilepsy affecting the whole body. A general seizure can cause a dog to fall on his back, convulsions of all limbs, teeth grinding, foaming, incontinence, barking or shouting. But local seizures can only cause dog seizures.

Causes of dog epilepsy
Seizures can be considered a symptom

Epilepsy makes dogs always feel tired and lazy in life.
Below are some common causes of seizures:
Hypoglycemia (low blood sugar). When blood sugar drops below 70 milligrams per deciliter (mg / dl) of blood, some dogs will become weak, have less concentration, and when blood sugar levels fall further, epilepsy will occur. Seizures are the body's way of releasing glucose from muscle tissue to raise blood sugar levels, which often occurs in small dogs and micro dogs.
Liver disease (hepatic encephalopathy). The liver filters toxins from the blood and abnormalities in the liver cause toxins to build up, resulting in lethargy, disorientation and seizures.
Inflammatory or infectious diseases affecting the nervous system can cause seizures of dogs.
Poison or toxin
. There are many toxins and toxins that can cause seizures such as bromethalin (a rat poison), pyrethrins or organophosphates (common ingredients in over-the-counter flea medications), hexachlorophene, chlorinated hydrocarbons, metaldehyde , lead, myotoxin and strychnin.

Dogs with brain tumors may also have epilepsy. A common sign of a brain tumor is seizures but other symptoms can also develop over time such as abnormal eye reflexes, difficulty walking, tremors, behavior changes and disorientation. Causes of brain tumors may include:
Tumors arising from brain tissue include meningiomas, gliomas, choroid plexus tumors, etc.
Tumors can arise from living tissue in the brain such as from the pituitary gland (pituitary tumor).
Tumors that can spread to the brain from other organs like lung cancer can metastasize to the brain.
Tumors can develop in brain tissue from other areas
. For example, a nose tumor may develop in the brain.
Head injury: Head injury may include blunt injury (physical injury due to collision) or traumatic injury. Dogs often have head injuries from cars or other vehicles and blunt injuries from bats or other flying animals. Dogs can also be trampled, stabbed in the door, crushed by chairs and a variety of other causes of injury. Such injuries can cause swelling of the brain tissue resulting in disorientation, lethargy, weakness, abnormal eye reflexes, tremors and possibly seizures.

Heat shock in dogs can also cause seizures. An abnormally high body temperature (from 40.5 to 43
.3 degrees C) causes the nervous system to be damaged and cause thermal shock. Symptoms of heat stroke include lethargy, weakness, depression, seizures, tremors and / or coma. A common cause of heat stroke can also be dogs staying in secret places for example, cars that are closed in the middle of a hot summer.
When a seizure occurs, you need to get your dog to a veterinary examination and treatment immediately.
