Resource guarding is a behavior exhibited by dogs when they perceive a threat to a valuable resource in their possession. Dogs consider anything valuable, from their favorite toy to a food bowl, and they may show aggressive behavior when someone tries to approach or take away the item they are guarding. Resource guarding is a natural dog behavior that helps them survive in the wild, but it can become a dangerous problem if a dog is willing to bite or fight to keep an item. Some common items that trigger resource guarding in dogs include food, toys, and space. Resource guarding can stem from fear and anxiety, frustration, territoriality, or conflict. It is important to identify this behavior early and use proper training techniques to improve it. While resource guarding is a normal and natural dog behavior, it should be discouraged before it becomes a problem. If a dog shows signs of resource guarding, it is recommended to seek help from a veterinarian or a professional dog trainer.
