It's important to note that "Springer rage" is not a recognized medical condition or behavior in English Springer Spaniels. It is not a common behavior in the breed, and any aggressive or overly excitable behavior should be evaluated and treated by a professional dog trainer or veterinarian. English Springer Spaniels may display aggressive or overly excitable behavior for a variety of reasons, including lack of proper socialization or training, fear or anxiety, pain or discomfort, certain medical conditions, or genetics. It's necessary to rule out any medical conditions that might be causing the behavior, and if it is not medical related, it is essential to work with a professional dog trainer or behaviorist to understand the underlying cause of the behavior and develop an appropriate training plan to address it. With the right training and management, most dogs can learn to overcome aggressive or overly excitable behavior.
