Involuntary Muscle Trembling in Dogs

An involuntary and some what rhythmic muscle contraction and relaxation involving to and fro movements (twitching) of one or more body parts is known as tremor. The tremors can be rapid or slow and can occur in any part of the body. They are visible to the naked eye and can even be felt by touching affected area. Tremors can be localized (occuring in an specific area of the body such as head, hind limbs) or generalized.

Young to middle aged dogs are usually more affected. It is believed that dogs with white coats are predisposed to tremor syndrom although dogs of all coats can have this condition. Some breeds are believed to be at a higher risk including chow chows, springer spaniels, Samoyeds, Weimaraners, Dalmatians, Doberman pinschers, English bulldogs and Labrador retrievers. Predisposed dogs to tremor syndrom are known as shaker dogs. 

Involuntary tremor in any part of the body is the most obvious symptom of tremor syndrom.
