Aggressive dogs

Aggressive dog breeds are fascinating due to their strong behavior, which often results from a combination of instinct, reactivity and upbringing. Some breeds are more prone to aggressive behavior due to their genetic predisposition or protective instincts. In breeds such as the Cocker Spaniel, the clinical picture of spontaneous aggression can also play a role.

What causes aggressive behavior in dogs?

Aggression in dogs can be influenced by various factors, including lack of or incorrect socialization. Some dogs are naturally more protective, which makes them appear more aggressive towards strangers or other animals. In some cases, a painful experience or traumatic past can also influence behavior.

Reactivity vs. aggression

Dogs that bark at other people or dogs on a leash are often referred to as "aggressive". An important distinction is that reactivity does not always equate to aggression. Reactive dogs often react quickly to new stimuli, such as loud noises or unexpected movements, but this does not mean that they want to attack the trigger for their reaction.

Diseases that can trigger aggression

Some dogs suffer from diseases that can cause aggression. One example is the clinical picture of spontaneous aggression in Cocker Spaniels. This involves sudden, seemingly unprovoked bouts of aggression that are linked to certain medical or genetic factors. Accurate diagnosis and treatment are crucial in such cases.
