How do I stop my dog from aggressively barking and biting at visitors?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Male | neutered | 11 years and 3 months old | 28 lbs

How do I train my dog to not do something he knows he shouldn’t be doing? This isn’t about being a naughty dog, but rather an obsessive dog. My dog is very smart and almost has the personality of a human, so he knows what we like and don’t like him doing. We have had the same maid since he was a few months old, and every morning when she arrives, he barks at her very aggresively and tries to “bite” her ankles. He knows he shouldn’t do it because we have scolded him, but he can’t help it.

While you may think he "knows he shouldn't do it" that doesn't mean he actually does, or isn't still wanting to do it. It could be that the maid coming by is extremely stressful for him, or he has fear associated with it- especially if you scold him every time. In his mind, he may think maid comes over = I get yelled at, so he tries to shoo away the maid in the hopes he won't be yelled at or scolded.

Speaking with a trainer or behaviorist about BAT (Behavioral Adjustment Training) is a good idea. This can help nervous or fearful dogs desensitize to certain stimulus through positive, gradual introductions, rather than forcing him into a fearful situation. Moving him to another room or outside until you can work with a trainer can also help and can keep your maid safe from being bitten if he's actively trying to bite her.

Trying to make her coming by a positive experience instead of a fearful one may also help. When she comes by, have her toss him a treat and then ignore him, or give him a special Kong or toy filled with his favorite snacks, so that he begins to associate maid coming over = fun! instead.

As aggression is a very complicated issue, I highly recommend working with a trainer or behaviorist in person so that they can observe and work with you to positively change Brownie's behavior. In the US you can find a list of nearby behaviorists here: http://www.dacvb.org/about/member-directory/

How to stop my dog from biting strangers and barking at the mailman?

Aggression toward people is a very complex and serious issue so I highly recommend speaking with a veterinary behaviorists near you. A veterinary behaviorist is a vet that specializes in behavior and they are able to work with you on both a training plan, as well as prescribe medications to help with stress or anxiety during training. Most behaviorists can utilize a program such as BAT (Behavioral Adjustment Training) that helps to desensitize your dog to triggers (such as men or the mailman), accept touch or calm handling, and help reduce overall stress and anxiety. They also work with you in person which can help ensure all training is done in a safe manner for both you and your dog. You can learn more about them here: https://www.dacvb.org/page/about

My new dog bites visitors. How can I stop his aggressive biting?

Aggression toward people is a very serious and complicated topic, and one that should be worked with by a local animal behaviorist or trainer in person. It is best to work together to address the root cause behind the biting (fear, uncomfortable in new home, undersocialized, etc) and then work on a training plan together than can ensure both Okami and any visitors remain safe. In the meantime, moving Okami to another room and not having visitors approach, or just tossing a treat if they walk past where he is is best to avoid direct contact and anyone getting hurt. In the US, this site is useful for finding a certified behaviorist near you that can get you started on resolving the issue: http://www.dacvb.org/about/member-directory/

How to stop my dog from barking excessively and biting visitors?

Poor Bear! Excessive barking and howling when left alone is a very common sign of separation anxiety in dogs. Barking and growling at visitors and strangers on walks is also a very concerning behavior, especially in such a young dog. These are complicated problems that are difficult to address adequately in a forum like this, so I would strongly recommend making an appointment with someone who can help you in person. Ideally, it would be best to see a veterinary behaviorist who can evaluate Bear and help you put together a detailed training plan to work on these problems. This may include prescription anti-anxiety medication, since it sounds like his issues are fairly severe. You can ask your veterinarian to refer you to your nearest board-certified behaviorist for an evaluation and treatment plan.

How to stop my dog from being aggressive to visitors and strangers?

Hi there! I'm sorry to hear that you're having this problem with Hanna. Most aggression towards strangers in the situations you describe are a result of fear and anxiety - Hanna may not be comfortable around people she doesn't know, and barks and growls to try and get them to go away. Treatment for this problem is based on teaching her to associate good things (usually treats) with seeing new people, along with making sure that she always has plenty of space and is never forced to interact if she doesn't want to. A basket muzzle can certainly be used to help keep everyone safe, if needed, but it shouldn't be used to put her in uncomfortable situations. Aggression issues in dogs are complex and can be difficult to work on safely without help, so I would strongly recommend getting in touch with a veterinary behaviorist who can work with you in person. He/she can evaluate Hanna to help determine what is causing her aggressive behavior, and will help you put together a detailed training plan to work on the problem.

My dog barks at visitors at the door. How do I manage this fear?

Your best option is to have a professional trainer come to your home and evaluate her during these situations. They will be able to give you the best advice. Behavior issues are not quick fixes and if you don't know what you are doing you could make the dog worse instead of better. These types of behaviors should be handled by a professional. I don't know where you are located so just do a google search for in-home professional dog trainers (like Bark Busters or Sit Means Sit) or you can probably get a reference from your veterinarian.

How to stop my dog from guarding my room and biting visitors?

Hi there! When it comes to resource guarding of a specific location or area of the house, this is a fairly complex problem that can't really be addressed properly in this type of format. I would recommend getting in touch with a veterinary behaviorist or a good reward-based trainer who can evaluate her in person and help you put together a detailed plan to work on this behavior. You can search for a board-certified veterinary behaviorist in your area here: www.dacvb.org or a qualified trainer here: www.ccpdt.org In the meantime, if she only shows this behavior with people she doesn't know, I would recommend separating her from visitors by putting her in a crate or another room with the door closed to avoid any further problems until you're able to get some in-person assistance.

How to stop my dog's aggression towards visitors in our home?

Aggression is a very complex issue that is a bit more to handle than the scope of questions on here! If Rocky is being aggressive toward people that come to visit, and is growling, attempting to bite them, etc, I highly recommend seeking out a trainer or animal behaviorist near you that can help. Usually, aggression and other issues where the dog is very reactive require the supervision of a professional to create a tailored training plan to help desensitize your dog to the trigger in a safe manner for both your dog and you and your guests. (Behavioral Adjustment Training, or BAT is one technique used.) In the meantime, separating Rocky from your guests if he does attempt to bite, or having your guests ignore him completely to prevent stressing him out further may help until you can see a trainer.
