These aggressive behaviors as well as other fear-related behaviors do not improve with age. Instead, they worsen with maturity and in severe cases, could lead to a bite towards a family member. Mild resource guarding can either be reinforced, ignored, or punished. If you are reinforcing low-level resource guarding, you will keep the behavior at its current intensity. Suppose the low-level resource-guarding behaviors are put on extinction or punished, this will cause the behavior to escalate. Punishing low-level resource guarding eliminates those behaviors, but the motivation to keep the item and get the handler to go away remains and often grows. As a young puppy matures and the environment runs its course, resource guarding and touch sensitivity become more apparent and often dangerous for everyone involved. Touch sensitivity is very similar to resource guarding in terms of the behavior’s progression. As puppies age, they become more sensitive to being touched.
