Causes that may cause twitching in dogs:

1. Dogs may occasionally twitch while sleeping, which is normal.

2. Poisoning may be caused by food or medicine. Generally, dogs will also be accompanied by foaming at the mouth. It is recommended that the owner induce vomiting for the dog immediately. If it is ineffective, it needs to be sent to the hospital for treatment in time.

3. It may be caused by diseases such as meningitis, encephalitis or brain parasites. The owner needs to send the dog to the hospital for examination as soon as possible.

4. Dogs infected with canine distemper virus may also cause convulsions in the later stages of the disease.

5. Epilepsy. If the dog has convulsions but recovers after a period of time, it is epilepsy. Epilepsy cannot be cured, but it can be improved through medication.

6. Calcium deficiency, which will occur in large dogs, elderly dogs, and pregnant bitches.
