Dog Barks at Strangers: How to Stop Dog Anxiety

In this Omaha dog training session, we worked with Rowdy, a 5-year-old Black Lab. He is scared of new people, so we used counterconditioning and tips to help when a dog barks at strangers.

Tips to Help Dogs who Bark out of Anxiety

Knowing that Rowdy had an intense fear of meeting new people, I used a positive reinforcement based greeting that worked wonderfully. Rowdy didn’t bark once which according to his guardian was a big difference from his normal, barking behavior when meeting new people.

We started off the session by sharing a number of dog behavior tips to help with exercise and mental stimulation.

Feeding out of a snuffle mat or an Omega Treat Ball is a great way to entertain a dog. We also went over lessons like how to teach a dog to stay calm when people return home, how to train a dog to get off the couch and several other dog behavior tips.

While we were talking, Rowdy oscillated between pacing, sitting or laying down and standing up to stare or bark. I could see he was an anxious dog from the jittery movements that are a tell tale sign of cortisol in the dog’s blood.

Anytime you have a fearful dog, one of the best things you can do is give them space. We tried to avoid all the common mistakes people make with scared dogs; we gave him space, avoided direct eye contact, didn’t try to pet him and waited for him to come to us.

We also helped things along by dropping treats on the floor to encourage Rowdy to approach us and keep moving. We made sure to wait 2 seconds or more before dropping another treat as Rowdy barked.

This is an important delay as anything a dog is doing when they receive attention or a reward can amplify the behavior they are trying to stop. So giving a treat within 2 seconds of a bark is a great way to promote and reward unwanted dog barking; a classic mistake.

Why Does my Dog Bark at Strangers?

Dogs often bark at strangers for reasons like territorial instincts, fear, anxiety, excitement, or lack of early socialization. Some may also bark simply to get attention.

Territorial dogs see strangers as threats, while fearful ones bark to cope with discomfort. Others may just be eager to interact but don’t know how to express it calmly.

Addressing this behavior starts with identifying the cause and using positive, consistent training methods. Socialization—gradually exposing your dog to new people and situations—can help build confidence. Reinforce calm behavior with treats or praise, and use desensitization by starting interactions at a comfortable distance.

Training cues like “sit” or “stay” help redirect focus, while ignoring attention-seeking barking teaches that calmness earns rewards. Avoid punishment, which can worsen fear or anxiety.

With time, patience, and positive reinforcement, when a dog barks at strangers, it’s often possible to teach calmer responses and build better behavior.

What to Do When a Dog Barks at Strangers

Next, we addressed Rowdy’s barking behavior. Rowdy barked to disagree when people arrived, moved around or stood up or at sounds he heard. Many scared dogs bark a lot because they lack confidence or have had bad experiences. I believe this is true for Rowdy.

He started acting this way after staying in daycare for a week and it progressively got worse.

I made sure to cover the common mistakes people make when their dog barks. This includes yelling for quiet or punishing the dog. These all make matters worse. If they do stop the barking, they often cause other problems because they don’t address the reason why the dog is barking in the first place.

As a dog behaviorist, I always want to get to the root of the dog’s behavior problem instead of chasing symptoms like barking. In Rowdy’s case, he was barking to get the person or thing to go away.

I suggested that the guardian cover the bottom of the windows facing the street. This way, the dog won’t think they’re barking made the person or animal in front of the house leave.

How to use Counterconditioning to Stop Dogs From Barking

I like to use counterconditioning to help dogs who bark or act aggressive to things they are afraid of, don’t understand or dislike. You can learn how to use counterconditioning to stop dogs from barking at things by watching the free positive dog training video below.

One of the great things about this trick to stop dog barking is how simple it is. Anyone can do it, even if you aren’t a professional dog trainer. Many of my clients have successfully used this easy way to stop dog barking.

I would like the guardian to have a friend or neighbor visit at least once a week. More visits would be better to practice this technique. Dog behavior modification is very much a numbers game.

My clients who do this once a week or more see much better and faster results. This is true compared to those who do it less than once a week.

I saw that Rowdy barks when he gets direct eye contact. So, I guided the guardian through a focus exercise.

I also suggested that the guardian practice a delayed entry exercise. This will help stop Rowdy from jumping on her when he gets too excited, like when she comes home.

Ideally she practices this exercise 3 or more times a day as this is a serious problem due to a few health concerns.

I would like to see the guardian use this method every time she comes home in the next few months. This way, she can enjoy the nice weather and avoid waiting outside in the cold when winter comes.

Since Rowdy barks at the neighbor dog when they come into his backyard, taking the dogs for a walk together may help. You want to build up positive associations when dealing with an anxious dog and repeated interactions or activities. This way, Rowdy sees the dog as a companion he shares a fun activity with.

To help the guardian remember all the positive dog behavior tips we shared in this in-home Omaha dog training session, we filmed a roadmap to success video that you can check out below.
