Brain

The dog’s brain weighs only 2-3 ounces but contains millions of nerves that are specified in controlling and coordinating the body functions. Nerves connect the brain to the rest of the body. The brain is a fragile organ and requires protection which is provided by the skull. Any issue in the brain can lead to several outcomes which depend on the affected region. Common signs of brain diseases include seizures, paralysis, discoordination, behavioral changes, and mental illness.
