Why Do Dogs Growl & What To Do

Growling is a normal part of canine communication. Many people think of a dog's growl as a warning or sign of defense, often meaning the dog needs space or is uncomfortable. However, growling is a complex vocalization that can occur in various situations. Understanding why your dog is growling, how to prevent escalation, and when to intervene is crucial for maintaining a healthy relationship with your pet.

Potential Causes of Dog Growls

Dogs growl for numerous reasons, depending on the situation and the individuals involved. Common scenarios in which dogs might growl include:

  1. Playing: Dogs often growl during play, which is usually accompanied by loose, relaxed body language and a playful demeanor.

  2. Greeting another dog or person: Growling during greetings can be a sign of discomfort or a request for personal space.

  3. Being verbally reprimanded or physically corrected: Dogs may growl in response to fear or discomfort caused by punishment.

  4. Lying down in a preferred location: Growling can be a way of protecting their space when they feel threatened.

  5. Possessing a preferred toy or high-value food item: Dogs may growl to guard their prized possessions.

How To Tell the Difference Between Growls

Play Growling: This occurs during playful interactions among dogs or between a dog and their owner. Play growling is typically characterized by a relaxed posture, wagging tail, and soft facial expressions. It’s a normal part of play behavior and not a sign of aggression.

Growling During Greeting: When a dog growls during a greeting, it’s often a warning for the other dog or person to keep their distance. This growl may be accompanied by stiff body language, a hard stare, and ears held forward or to the side.

Growling When Verbally Reprimanded or Physically Corrected: This type of growling is a response to fear or discomfort. It indicates that the dog feels threatened by the punishment and is a sign of distress.

Growling When Approached While Lying Down: This growl is a protective behavior. The dog may lower its head, avoid direct eye contact, and pull its ears back. It signals that the dog does not want to be disturbed.

Growling When Approached While Possessing a Preferred Toy or Food: This is a guarding behavior. The dog makes direct eye contact, bares its teeth, and hunches over the object. It’s a warning to stay away from their valued item.

What Not To Do When a Dog Is Growling

It's crucial not to yell at or hit your dog when they growl. Punishing a dog for growling can lead to increased aggression and fear. Instead of addressing the underlying issue, punishment can teach the dog to suppress the growl, which is a vital warning signal. This suppression can lead to sudden, more severe aggression without warning.

What To Do When a Dog Is Growling

When your dog growls, it's essential to acknowledge the growl and redirect your dog to a more desirable behavior. For instance, if your dog growls at someone during a walk, interrupt the behavior with a neutral noise like a quick whistle or finger snap. Then, redirect your dog's attention by asking them to perform a command, such as "look" or "sit." Reward them with a treat and praise when they comply. This technique teaches your dog to focus on you and helps counter-condition their response to the trigger.

If your dog frequently growls at strangers, carry a treat pouch during outings. As soon as you see a stranger, give your dog a treat before they start growling. This proactive approach helps teach your dog to associate strangers with positive experiences.

Training and Professional Help

Training your dog using positive reinforcement techniques can help address growling and other undesirable behaviors. If you're unsure how to proceed, consider seeking help from a professional trainer who uses positive reinforcement methods. Avoid trainers who use punitive techniques, as these can exacerbate fear and aggression.

If your dog's growling persists, or if they refuse rewards and show signs of severe fear or aggression, it may be time to consult a board-certified animal behavior professional. These experts can provide specialized guidance and create a tailored plan to address your dog's behavior.

Real-World Perspectives: Insights from Dog Owners

Many dog owners have experienced the challenge of dealing with a growling pet. For instance, Sarah, a pet owner, shared her experience with her German Shepherd, Max. Max would growl whenever strangers approached the house. Initially, Sarah tried to correct this behavior by scolding Max, but it only made the situation worse. After consulting a professional trainer, Sarah learned to use positive reinforcement techniques to redirect Max’s attention. Over time, Max's growling reduced significantly, and he became more comfortable around strangers.

Another dog owner, Mike, had a similar issue with his Border Collie, Luna. Luna would growl when Mike approached her while she was eating. By working with a behaviorist, Mike learned to gradually desensitize Luna to his presence during mealtime. He started by standing a few feet away and tossing a treat toward her. Slowly, he decreased the distance, always rewarding Luna for calm behavior. This method helped Luna feel less threatened, and the growling stopped.

Understanding why dogs growl and how to respond appropriately is crucial for maintaining a positive relationship with your pet. Growling is a natural form of communication that should not be punished. Instead, acknowledging the growl and redirecting your dog’s behavior can help address the underlying cause and prevent escalation.
