Dogs bark for various reasons, and they even have different barking styles, hinting at what they want to convey.

When your dog barks at other dogs, they are communicating something to each other. It can be territorial bark or just an attention-seeking bark.

We will have a look at some of the common reasons your dog barks at other dogs.

1. They Want to Play

Let us start with a positive reason: if your dog barks at other dogs, it may mean that your dog wants to have a playful session with them.

If you are around a dog park or crossing the walkway where your dog sees a canine friend, then he may bark at him, asking him to join in.

2. Marking the Territory

Marking the Territory

If your dog is in your house and sees other dogs through the window or the door, then the barking will start letting other dogs know that they are coming too close to his territory.

Dogs consider their porch, the cars they travel in, and even the regular walkways they take as their territory, and if some other dogs are seen around their territory, then your dog will bark.

3. To Join the Pack or to Seek Attention

If your dog is barking at other dogs, it may be because he wants to join the pack and play with them. This happens when your dog is friendly towards other pets.

They may also bark just to get the attention of other dogs, and it’s totally normal amongst them to bark and communicate.

4. Reactive


Your dog may bark at other dogs because they are reactive, which means they react when triggered by something like fear, distress, bad experiences, or other things.

If your dog sees another dog, they may bark and start lunging or pulling, it primarily shows fear and anxiousness in dogs. This may also occur if your dog lacks training, has less social interaction, and can even be genetics.

How to Stop your Dog from Barking at other Dogs

Dog barking is natural and should not be worrying if it is just a hello down the road to their other canine friends.

Regular or aggressive barking towards other dogs should worry you, as it can be a sign of fear, stress, or anxiety that your dog is releasing in their bark because they don’t know any other way to express their emotions.

You should not scold or shout at your dog when he is barking. Not only is it bad for your dog’s mental health, you are also giving him attention and reinforcing the behavior.

1. Identify the Problem

You should try to know the reason behind your dog’s bark, whether the bark is about the territory, or just reactive, or there is any other reason. Knowing the reason will ease your trouble and help you control and avoid such instances.

2. Solve the Problem

Solve the Problem

If your dog barks at other dogs just to mark their territory or to seek attention, then training and socializing is a way to stop them from barking.

Finally, do not punish or scold your dog when your dog barks at other dogs. Dogs are meant to bark, and that’s their way of talking and greeting other dogs. You punishing him can make him bark more.

3. Take Professional’s Help

If barking continues and gets aggressive, then try training, dog schools, or getting help from experts to control this. If they are too reactive then you can try to manage reactivity in your dog, and the best possible way would be to take the help of a trainer or a dog behavior expert.
