According to the American Society for the Prevention of Cruelty to Animals (ASPCA), aggressive dogs are the number one problem dog owners face. Aggression instills fear and can turn even a tiny Chihuahua into a scary dog. Many owners, unable to manage the behavior, find themselves researching where to surrender their pets. A dog that seems naturally aggressive is usually exhibiting a series of behaviors. Often, this represents a household dynamic in which the dog is trying to communicate something. Whether it’s towards strangers or other animals, the dog wants to indicate something is amiss.
