Whatever you're doing, just stop. If your dog's growl threshold is near his bite threshold – that is, if there's not much time between his growl and his bite, get safe. If his growl doesn't mean a bite is imminent, stop what you're doing but stay where you are.
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.
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. Wait until your dog relaxes, and then move away, rewarding your dog for the relaxed behavior. Take a look at the situation.
Straight off the bat you should be correcting your dog's growling and/or snapping with a firm “no” at the onset of the behavior. When he stops growling, reward him with a “good boy”, or in the beginning, a treat if it's handy at the exact moment of training so that he knows what he is being rewarded for.
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.
Threat or Fear
This type of growl with a low volume and a deep, rumbling sound usually happens when a dog feels scared, possessive, or threatened. It is a warning growl that indicates their discomfort in a particular situation.
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.
The act of holding a dog down forcibly as a correction is generally called the "dominance down." It is inappropriate, ethologically absurd, and completely counterproductive when interacting with dogs. In a nutshell — don't do it. Ever.
There are multiple reasons that a dog may exhibit aggression toward family members. The most common causes include conflict aggression, fear-based, defensive aggression, status related aggression, possessive aggression, food guarding aggression and redirected aggression.
The Growl: Dogs do growl while playing, but there are two ways to tell different growls apart. An aggressive growl will be accompanied by snarling and snapping, while a playful growl is just a sound, accompanied by relaxed body movements (no tension).
Dogs Growl to Communicate
After all, it usually precedes a bite. But, at its core, growling is about communication. Dogs growl to indicate they're unhappy, uncomfortable, or even fearful about a particular situation.
Dogs emit two primary growls: one for play and one for all other times when dogs are angry, a study confirms.
Dogs may growl during playtime to show their enthusiasm or excitement. If you observe that your dog is wagging its tail while growling, it's a good indication that they are enjoying themselves.
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.
Punishment of the growling behavior hinders your dog's ability to communicate how he's feeling and decreases his warning signals before a bite. Dogs that have been punished for growling or other aggressive warning signals may progress faster into a bite, and they may display fewer warning signs.
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 best thing a pet parent can do when their dog has escalated aggressive behavior is to remove the dog from that situation or remove the trigger that the dog found threatening. If you're the reason the dog is directing the aggressive behavior, step out of sight.
Dogs can become more bad-tempered for a variety of reasons. It's not uncommon for older dogs to growl or snap at a puppy, for example, while irritability can be a sign of underlying health and wellbeing issues in your pet.
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.
