My dog bites guests. How to train him to be calm with guests?

It is likely that he is being territorial and trying to gaurd the house. It is very diffucult to break such behavioural habits and to be honest he would need to be assessed in his home environment to understand exactly what his triggers are. Because this is such a serious issue in would recommend contacting a pet behaviour specialist asap to come to your house and work with him. In the mean time you may need to consider putting a humane Baskerville muzzle on him to protect your guests.

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.

Get him acclimated to people so it isn't a big deal when you have company. Make him "work" for everything (food, attention, walks, etc.). This can be as simple as having him sit or wait before being fed, taken out or played with. When company arrives, make him wait to greet. Do not allow him to initiate contact. Use a leash to control him if necessary. A head harness such as the Gentle Leader or Halti can provide a means to control and quickly correct negative behavior. Ignore him when he barks at company. If he jumps up, turn away from him. Be consistent and be firm. Do not yell as this will likely get him more riled up.

This is very normal behavior for a puppy this age - jumping up is a natural greeting behavior for dogs, and biting and mouthing are how puppies explore the world. You will need to be patient and consistent to teach him what you want him to do. When people come to the house, he needs to be on a leash or in another room behind a baby gate until he calms down. Praise and reward with treats when he keeps all four feet on the floor, or teach him to sit for greetings. Make sure that he has a variety of different toys to provide an appropriate outlet for this behavior - long floppy rope or fleece toys for tugging, plush toys for biting and carrying, and smaller toys or balls for chasing and fetching. Providing lots of things to chew on can also help, especially when you are busy or have company over - try things like bully sticks, cow or pig ears, rawhide chews, and puzzle toys like a Kong stuffed with peanut butter. If these things don't help, I would recommend getting in touch with a good reward-based trainer who can work with you in person to teach more appropriate greeting behavior.

Hi there and thank you for using pet coach. If Sherlock is fearful and aggressive towards strangers, it is going to be too difficult to train him before the holidays as training takes time. If you are going to have people over then I would keep him in a separate room or a crate. I would also recommend using a product called NaturVet Quiet Moments with Melatonin for dogs. You can find these at your local pet store or online. I hope this helps! Please let me know if you have any other questions.

It's likely that Ivy is just really excited and showing this by barking. Obviously this is unwanted behavior. You need to start training impulse control and teaching her to sit or place before people come over. Treat her for calm behavior and slowly progress to gradually introducing people when she is well behaved. If she is barking she gets ignored as petting her cuddling her will encourage 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.
