Resources and their defence are a natural part of our dogs' lives. They protect what they consider important - whether it's food, toys, a place to sleep or even us humans. This behaviour has deep roots in evolution and is closely linked to survival and social order within groups.
The defence of resources is not a "problem", but a normal expression of their needs and their perception of the environment. However, frustration caused by misunderstandings or mishandling can turn this behaviour into aggressive behaviour. Especially when dogs learn that resources are not safe or that they are "punished" for giving them away.
It is up to us, as dog people, to understand this behaviour and respond respectfully. Instead of causing frustration, we should show our dogs that resources are safe and that sharing or giving them away does not lead to a loss.
In the further course of the training plan, you can refer back to the exercises already shown (days 42 to 48) for the "off" signal to gently teach your dog that resources do not have to be defended. Equipped with this knowledge, you can understand your dog better and work together with him to create a harmonious everyday life.
