Bottom Line: When your dog growls at you I recommend that you listen to what your dog is saying. Immediately stop doing whatever it is that you're doing and move away.
Stop whatever it is you're doing or the person/animal eliciting the growl is doing. If you know that your dog growls right before a bite, then move away and get safe. If you know the growl doesn't mean a bite is imminent, stop what you are doing.
Why Do Dogs Growl? Growling is one way your dog communicates with you. It growls to let you know that it's afraid, in pain, or needs for you to back away from its possessions or territory. Often your first instinct is to run from a growling dog or to punish it for growling.
Growling is an important form of canine communication. It can indicate different messages, though most commonly it means that your dog is feeling threatened, protective, or she is attempting to scare off an impending confrontation.
You should never punish your dog for growling.
Growling is an essential part of a dog's language. When dogs growl, they are trying to communicate their stress about something happening in their environment. That could be them guarding a toy, seeing a stranger, or even just excited to see someone they know.
Don't Punish Growling
It's either benign or a symptom of stress in your dog. If you punish your dog for growling, you will only inhibit growling. You won't have done anything to address the underlying issue. For example, punishing your dog for growling in the presence of other dogs will stop the growling.
The most common reasons dogs growl are fear, possession aggression, territoriality, and pain. Some dogs also growl when playing. Play growling is often seen when two dogs are having a safe, healthy play session. In this case, the growling does not necessarily indicate aggression.
The most common causes include conflict aggression, fear-based, defensive aggression, status related aggression, possessive aggression, food guarding aggression and redirected aggression.
Most dogs assume a neutral or submissive role toward people, but some dogs will challenge their owners for dominance. A dominant dog may stare, bark, growl, snap, or even bite when you give him a command or ask him to give up a toy, treat, or resting place.
Many breeds are very protective, and many dogs have “their person” – so they will have a tendency to growl when someone else is approaching as a way to ensure that their special person stays safe. You may also see the behavior if they are friendly with other dogs and a new, unknown pet comes around.
Act like the alpha of the back and show him who is boss. Look him/her in the eye: When you give a command, look straight at your pet. Make sure he can see that you mean business and that it is not a command to be disobeyed. Always hold eye contact with your pet, no matter how big or small he or she is.
“If your dog whines, barks, paws at you, or nudges you to get affection, this means that they don't respect your personal space and they won't listen to you in other areas of training and leadership.” This one may be tricky for dog owners.
Dogs will also growl when they are feeling frightened or stressed out. Most of the time this is a warning before the dog reacts aggressively. Although a dog may not always snap or bite after growling from fear or stress, it is still always best to be cautious.
Punishing a growl can be dangerous.
You teach your dog not to tell you when they are uncomfortable. They are still uncomfortable, or scared, or mad, but now they just don't say anything. They don't let you know. When people say, “The dog bit without warning,” it is often because the dog was punished for growling.
Wild dogs exhibit similar behaviors, opting to sleep in small, confined areas with pack members they trust to protect against predators. When your dog sleeps right next to you, he is demonstrating trust in his “alpha” human.
The best way to prevent your puppy from growling at strangers is to socialize your puppy to all kinds of people. That means different sizes, ages, ethnicities, etc. It also means people who look different such as people wearing hats or glasses or people using wheelchairs or canes.
Dogs use facial recognition to communicate with each other and human beings may not see facial features in the same way as dogs. When your dog growls at one person and not another, it might be that he sees a feature that is reminiscent of a threat to him in his memory.
Your dog could be growling because they are frustrated or feel territorial. On the flip side, your pup could be feeling playful or affectionate. Their body language and facial expression can tell the “tail.” If your dog is being aggressive, there are things you can do to teach them good behavior.
Your dog may be showing possessive behavior if they do the following: Growling. Snapping. Whining.
The safest and most effective way to treat an aggression problem is to implement behavior modification under the guidance of a qualified professional. Modifying a dog's behavior involves rewarding her for good behavior—so you'll likely be more successful if your dog enjoys praise, treats and toys.
