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

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.

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.

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.

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.

Poor Ruger! It sounds like he's extremely anxious - barking at things like this is how dogs communicate that they are scared and uncomfortable. Especially in a 5-month-old puppy, this is very concerning because this behavior is likely to get worse as he gets older without proper treatment. There is also a significant risk that this may progress to lunging and biting when he is an adult, which is extremely serious in a large-breed dog like a GSD. Because of this, I would strongly recommend making an appointment with a veterinary behaviorist who can evaluate Ruger in person and put together a detailed, step-by-step treatment plan to address this problem - success rates for treating behavior problems like this are highest when treatment starts while the dog is still a puppy, so I would do this now. Don't wait until he's older, or it will be much harder to make progress. The general approach to treatment for anxiety and barking like this involves teaching Ruger to be comfortable seeing strange people by associating them with treats and other good things - but for anxiety this severe, it will be extremely difficult to do this successfully on your own, which is why I really recommend seeing the behaviorist as soon as possible for some hands-on guidance. Medication may also be helpful, and the behaviorist can talk to you about this option as well. You can search for a veterinary behaviorist in your area here: www.dacvb.org

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

Poor Bandit! It does sound like he's very fearful of new people - this is a fairly common problem in dogs, and can be due to genetics, inadequate socialization as a puppy, and/or negative experiences with strangers in the past. The good news is, most dogs with this problem are able to improve tremendously with some help from a professional. I would recommend making an appointment with a veterinary behaviorist who can evaluate Bandit in person and help you put together a detailed treatment plan for him - this would normally include management recommendations to help keep him from being put in situations that are overwhelming for him, a training plan to teach him to associate new people with good things (usually treats!), and possibly also medication depending on the severity of his anxiety. It can be very challenging to try and do this on your own if you don't have any experience working on this problem, so I would definitely recommend having a behaviorist help you - especially since he does sometimes try to bite.
