How to Stop a Dog from Being AggressiveWhat Actually Causes Puppy Aggression?

First, you should be aware that there is a physiological process that can occur in puppies that goes all the way back to their primal, “fight or flight” instincts.  It can cause a whole load of chemicals to be released in their bodies, such as cortisol, adrenaline and noradrenaline.  These hormones send your puppy into a sort of “overdrive” state where they cannot control their emotions.   To watch a video where Professional Dog Trainer and Behavioral Specialist, Doggy Dan, discusses this, click HERE.   

how to stop a puppy from being aggressiveWhat Makes a Puppy Aggressive?

I think it’s important for you to have a complete understanding of what is happening in your puppy’s brain when he becomes aggressive so you’ll be more capable of solving it. We’ll be discussing the solutions in this article.  But first, let’s discuss the three biggest reasons why puppiess become aggressive:

1.  Lack of Guidance.  Puppies need to be taught what sort of behavior is acceptable and what is not going to be tolerated.  Ideally, this training should happen when the puppy is young, and continue throughout the dog’s life.  The most important factor in providing guidance for your puppy is to make sure they know that you are in charge.  If they see you as “the pack leader,” they will instinctively follow your guidance on how to behave.

2.  Lack of Boundaries.  Just like children, puppies need boundaries.  If they don’t have boundaries, they can become overwhelmed, anxious and over-excited, and behavioral issues and aggression are often the result.  It’s also important to establish boundaries to teach your puppy that you are the leader and the provider.  Again, once your puppy sees you in this way, he’ll follow your lead, take direction from you, and he won’t feel like he has to be the one in control.

3.  Lack of Exercise or Stimulation.  Pent up energy or a lack of stimulation can cause a puppy to become aggressive.  They need an outlet to release tension so their energy doesn’t build up and cause them to misbehave or become aggressive.  Make sure your puppy is getting enough exercise – at least 30 minutes a day. (But not TOO much exercise.  Puppies require a lot of sleep.  Read my article, Why Do Puppies Sleep So Much? (includes video)

How to Stop a Dog from Being AggressiveWhat to Do About an Aggressive Puppy

Doggy Dan has developed a step-by-step dog training program called, The Dog Calming Code, specifically made to stop dog aggression.  According to Doggy Dan, if you want to understand how to stop a puppy from being aggressive, you must first realize that your puppy is making his own decisions because he has not received proper guidance, he doesn’t understand his boundaries, or he’s trying to release pent-up energy (or all three!)

And, as we discussed earlier, your puppy will experience a rush of chemicals in his body when he becomes aggressive, making it nearly impossible for him to calm himself down and listen to you.  Check out Doggy Dan’s program for step-by-step instructions on how to solve this.

Puppy Aggression Toward Other Puppies

Here’s a breakdown of some of the reasons why your puppy is being aggressive towards other dogs or puppies.  Your puppy may be aggressive due to a combination of  the reasons we’ve already discussed, plus these reasons:

1.  Dominance.  Dogs by nature, whether they’re in the wild or domesticated, follow pecking orders. Dominant dogs take the lead, and submissive dogs follow.  Most dogs are able to sort out who’s the leader and who’s the follower without violence or aggression.  However, if two dominant dogs are brought together, it can be a problem.  If both dogs believe they are the leader, they’ll fight to remain dominant.  And if neither dog submits, this can become dangerous.

The solution is for you to show your puppy that YOU are the dominant one.  YOU are the pack leader.  When you’ve effectively communicated to your puppy that you’re the one in charge, he’ll have no reason to try to establish himself as the dominant dog to other dogs.

2.  Fear.  Puppies will often act aggressively due to fear.  If a new dog is introduced into your puppy’s environment, your dog might become frightened that their territory is being invaded.  This is common with shelter dogs or dogs who have had to fend for themselves.  If they have a fear about food being limited or that their safe space is being taken over by another dog, they’ll become aggressive to protect what they have.

What’s the solution?  Again, if you take the appropriate steps to establish yourself as a competent provider and the one in charge, your puuppy can relax and know he can count on you to make sure his needs are met.  Puppies who live in a house where the owner is a strong leader can relax and not feel like they have to fight.

3.  Stress.  Stress of any kind, such as a sudden change in the household, a recent move, or even simple things like the doorbell ringing, can result in your puppy’s stress levels building up.  All that built-up stress has to be released, and puppies will often redirect it on to each other.  The solution is to realize the impact stress can have in your home and for your puppy, and create a calm energy so your puppy can relax.

4.  Lack of Training.  Finally, a lack of training can be the reason why your puppy is being aggressive.  The lack of training can include a lack of socializing your puppy, not teaching basic command training such has how to come when called, and how to remain calm around other dogs.  It can also involve a failure to set boundaries and rules for your puppy (such as not allowing them to jump on you).  If the puppy isn’t clear on the rules and boundaries, he’ll become confused and start “arguing” with the other dog(s) about what’s appropriate.

how to stop a puppy from being aggressivePuppy Aggression Towards People

Perhaps your puppy’s unpredictability has caused you to be afraid to have people over, for fear someone might actually be injured.  Or worse, perhaps your puppy has even become aggressive toward you.  Puppy aggression towards their owners and towards people is serious and can become dangerous as they get older (and bigger!)

You can calm your puppy’s emotions with the very straight-forward, simple, yet extremely powerful exercises in Doggy Dan’s program, The Dog Calming Code.  If you’re concerned about safety and you feel the matter is urgent, I strongly suggest you check that out.

How to Stop a Dog from Being AggressiveBottom Line on How to Solve Puppy Aggression: You Have to Be the Pack Leader

The most important concept to grasp is that your puppy must look to you as the pack leader. You need to convince him that you are the decision maker, so he’ll know he doesn’t have to be. Only then can he relax and not become aggressive toward you, other people, or other dogs.

Once you have convinced your puppy that you are the pack leader, you’ll soon see he’ll start to take notice of how you are behaving.  Instead of just suddenly becoming aggressive, he won’t just act – he’ll look to see how YOU are acting, then copy you. Remember, dogs are pack animals and they follow the pack leader.
