The meingess, the membranes enveloping the brain, are liable to inflammation. Symptoms are great drowsiness, with sudden spasmodic movements of the muscles of the head and chest during sleep. The disease is often produced by fits. In this and other brain troubles there is a disposition to walk in circles, always to one side, and the sight is so affected that the dog runs against obstacles. Treatment by the amateur is of no avail; call in a good veterinarian or your family doctor.
