I don’t know if you have ever seen dogs twitching when you were raising dogs. Many owners will think that this is just caused by the dog’s calcium deficiency. In fact, it is not the case. Below, the editor will tell you in detail what causes the dog’s whole body twitching. Let’s find out together.

1. Canine distemper

When dogs are infected with canine distemper virus, they will develop symptoms such as listlessness, loss of appetite, vomiting, diarrhea, biphasic fever, etc. In the later stages of the disease, dogs will develop symptoms of systemic or local postural convulsions. This virus is mainly susceptible to puppies that have not been vaccinated. Therefore, if the dog has not been vaccinated, the owner should consider this situation and take the dog to the pet hospital immediately for examination and diagnosis.

2. Epilepsy

If the dog has convulsions all over the body but gets better after a period of time, and the spirit and appetite were normal before the onset, it may be suffering from epilepsy. Because epilepsy cannot be cured, owners can only go to a pet hospital to buy anti-epileptic drugs and feed them to their dogs to control the disease. When the dog has an epileptic attack, the dog's tongue should be taken out of the mouth to prevent it from being bitten.

3. Poisoning

If the dog accidentally eats certain toxic substances, such as rat poison, chocolate, disinfectant, etc., when the toxin invades the nervous system, it will cause the dog to have symptoms of convulsions all over the body, accompanied by symptoms such as foaming at the mouth, drooling, violent vomiting, etc. In this case, the mortality rate is relatively high, and the dog needs to be taken to the pet hospital as soon as possible for a large amount of infusion, detoxification, and liver protection.

4. Rabies

The most obvious sign of a dog suffering from rabies is convulsions all over the body, which also indicates that the rabies virus has invaded the dog's nervous system at this time, and will also be accompanied by madness, photophobia, and water fear. If this is the case, the owner needs to isolate the dog immediately, take protective measures to avoid being bitten, and notify the relevant departments to deal with it.

5. Encephalitis

Dogs suffering from encephalitis will also twitch constantly, accompanied by symptoms such as impaired consciousness, uncoordinated walking, and collision with obstacles. If you suspect that your dog has symptoms of encephalitis, it is best to take your dog to a pet hospital as soon as possible and let a professional pet doctor provide first aid and treatment.
