What It Means in Practice

Aggression can include growling, snarling, snapping, biting, and charging. It describes behaviour, not a complete identity or moral judgment.

What It Does Not Always Mean

Aggression does not mean the dog is bad, dangerous, or beyond help. It describes behaviour that serves a function — often creating distance or stopping an unwanted interaction.

Why Context Matters

Aggression can be motivated by fear, pain, resource guarding, territorial defence, or other factors. The motivation affects how it should be addressed. Professional guidance is strongly recommended.

Commonly Confused With

Reactivity

Reactivity is an over-response, often fear-based. Aggression involves intent to threaten, create distance, or harm.
