Aggression and Reactivity – Online Dog Training Course

Understand why your dog reacts, learn to recognise the warning signs and discover how to manage aggression and reactivity safely with this practical online dog training course.

Through eight focused lessons, you will explore the differences between aggression and reactivity, understand common causes of challenging behaviour, learn how to recognise early warning signs and discover when professional behavioural support may be necessary.

Important Safety Information

Aggression and reactivity can involve a risk of injury. This course is educational and does not replace an individual veterinary assessment or professional behavioural support.

Do not punish growling, force interactions or deliberately expose your dog to situations that may cause it to become overwhelmed. If your dog has bitten, is attempting to bite or cannot be managed safely, prevent further exposure to the trigger and seek appropriate professional help.
