Distemper convulsions are mostly neurological. About 10-30% of dogs have neurological symptoms (spasms, seizures, convulsions, etc.). Some have “irregular twitching”, for example, a chewing and frothing of the mouth when stimulated, which disappears when the dog eases up. However, this is a clear sign of a “persistent twitch”. Neurological symptoms appear, mostly in 7 to 21 days, but also from the beginning. In cases where the virus has damaged the brain, other neurological symptoms can be seen, such as epilepsy, spinning, abnormal standing posture, unsteady gait, ataxia, foaming at the mouth, paroxysmal twitching of the masticatory muscles and limbs and other neurological symptoms, which can easily be followed by sequelae.
