Help with dog aggression

[[email protected]]

Every time my corgi (4 years) meets a new dog he seems to want to tell them who’s in charge. This often leads to fights and he doesn’t back down and gets hurt. Even if this is a dog he’s seen a few times like when we are dog sitting. We have to separate the dogs and I don’t like doing it

Hi there, welcome to the forums!

Rehearsing this kind of behavior – where your Corgi feels the need to "tell" another dog who’s in charge – can quickly lead to a cycle of escalating tension, and each rehearsal only reinforces this tendency.

Over time, it increases his arousal and assertiveness in these situations, making it more likely that he’ll continue reacting this way or even increase the intensity of his behavior.

Here's the thing:  Each time your Corgi gets to “practice" reacting to other dogs with this assertive behavior, he’s reinforcing specific neural pathways associated with high-arousal responses. Essentially, he’s learning that this intense reaction is how he should respond in these situations.

With each experience, he might become quicker to react or react at a lower threshold, even with dogs he’s familiar with. This can put him at risk of becoming increasingly defensive and possibly intolerant of other dogs over time.

Finally, not only does he risk getting hurt during these altercations, but there’s also a risk that he might cause injury to other dogs, leading to potential safety and liability issues.

With dogs being placed in his "perceived territory" it's important to start with slow, controlled introductions in neutral spaces. Here is a general guide on introducing dogs: https://www.braintraining4dogs.com/members/archive/introduce-dog-new-dog/

These cases require consistent management and positive experiences, so that your corgi gets to feel more comfortable around other dogs without the need to assert himself. For support in these steps and for safety, I recommend  working directly with a professional who understands behavior modification can guide you through building a plan tailored to him.
