Hello, sorry to hear about Bandit. Fearful or territorial aggression may be the cause of his snapping and biting. The following is a hand out on how to manage these behaviors. Hope this helps. Fearful behavior is very common and may manifest as aggression or the appearance of aggression towards you, the dog owner. Although your dog may show aggression towards their owners or strangers including growling, biting, or lunging, the motivation behind this is often fear related. Look at the body language of your dog—does she look scared, cowering with its ears pulled back? If you are uncertain, your veterinarian can help you to determine if your dog is exhibiting fearful behavior. Dogs can become fearful for many reasons and in response to multiple situations. It is very important to identify the cause of the fearful behavior so that you can address the situation(s) appropriately or avoid them altogether. There may be only one trigger, or there may be multiple things that cause fearful behavior in your dog. Each should be addressed separately. Some signs of fearful behavior • Ears back • T ail tucked • Fearful urination • Rolling over and exposing belly • Crouching body posture • Avoidance of eye contact These signs may be more subtle, with your dog licking her lips, panting, or yawning. Basic guidelines for working with a fearful dog • One of the most important things is NOT to punish your dog when she is being fearful. This will just make the behavior worse, or incite aggressive behavior. Punishment techniques may include tugging on the collar, verbal reprimands, or shock collars in more severe methods. • Avoidance of the situation initially will likely benefit you more than trying to use “flooding” techniques. Flooding refers to repeated and prolonged exposure to the situation that is causing fear in your dog. This is a no-no, and avoiding the situation is preferred. • Some very basic obedience training and using a “watch-me” command to divert your dog’s attention away from the fearful stimulus can also be useful. The watch-me command is used to establish eye contact between you and your dog in the presence of the fearful stimulus so she is focused on you rather than whatever may be inducing fear. • The use of non-confrontational leadership training, in which your dog must perform tasks for food/attention/toys/treats, has shown to be helpful in fearful animals. These tasks can be as simple as following a sit command before the dinner bowl is placed on the ground.
