The symptoms of dogs are different depending on the location of the distribution of inflammation. If the inflammation is small and far away from the cerebral cortex, there will be disturbance of consciousness, which may manifest as over-excitement or depression, uncontrollable loud barking, Or aimlessly bumping into objects, or even twitching all over the body, showing weird behaviors such as turning in circles and retreating; if the inflammation is deep, it will cause the dog to suffer from general paralysis, cramps in the limbs, paralysis of the masseter muscles, vision and throat, dilated pupils, and collapse to the ground. Starting from the onset, the dog loses its response to external stimulation; if it is a dog with a relatively quiet personality, when the inflammation is mild, it will appear lethargic, less interested in external things, its eyes will be slightly narrowed, and its whole body will be limp. All dogs with encephalitis will have an elevated body temperature. This is a general standard. After the above symptoms appear, the dog must be taken to the doctor in time. The doctor will inject anti-inflammatory and sedative drugs according to the specific situation.
