Meningitis in dogs is usually caused by parasitic, bacterial or viral infections. Symptoms can generally be divided into two types, one is excited and bumping around, the other is muscle weakness, depression and swollen joints. At the same time, because the disease is very serious and has a high mortality rate, so it is necessary to immediately send the dog to the pet hospital for treatment, so as not to delay the treatment time.

1. Parasitic infection
   If a dog has not been dewormed for a long time, some internal parasites such as roundworms, heartworms and hydatids can cause meningitis when they migrate through the brain and central nervous system. The main manifestations are dogs hitting their heads on the ground, walking in circles and other symptoms, which require the use of circular saw to remove the worm body, and do a good job of anti-infection treatment.

1. Bacterial infection
   The most common cause of meningitis in dogs is bacterial infection which normally lives in the eyes, nose or mouth. When an infection occurs in one of the organs, the bacteria can spread and infect the brain. The transfer of bacteria such as bacterial endotitis, pneumonia, endometritis and other bacterial infection through the blood can cause infection that can be treated with antibiotics, diuretics, antibacterial and anti-inflammatory drugs.

1. Viral infection
   When a dog has distemper and rabies, these diseases can destroy the immune system of the dog. The virus enters the nervous system and cases meningitis. This situation has no specific treatment drugs generally, we can try to use antiviral drugs, anti-inflammatory drugs and other drugs for treatment.
