How should I address my dog's growling?
Never confront or try to correct a growling dog. Growling is a common and healthy behaviour among dogs that is used to communicate an important feeling at that time.
Instead, redirect with a scent to help your dog change their mindset and reward that change. Giving space, remaining calm and patient (being quiet helps too!) will help and allow our dogs to slowly change their own emotion for a better one that we can then reinforce with our attention.
