Hello Judith, Pup might be becoming possessive of you, which is similar to resource guarding, where pup views you as something they own and they try to keep others away from you. If this is the case, I would work on building respect for you now gently, using structure and obedience practice. Check out the following articles on methods and commands that can help with that. Listening and respect: https://wagwalking.com/training/train-a-doberman-to-listen-to-you Below are useful commands to help with communicating with pup. I would prioritize the Listening and respect methods from the article I have linked below, teaching Off, Out, Leave It, Heel, and Down from the articles below.

Have him toss pup a treat whenever he first enters the room where Bean is. Have him practice changing positions and tossing a treat if pup stays calm once pup is okay with him entering the room. Have him practice tossing pup a treat when he hugs you or sits next to you. Finally, once pup is comfortable with him, have him practice gently touch pup somewhere and give a treat, such as touch pup’s should and give a treat, touch pup’s collar and give a treat, ect… You and your son can both practice the touches with treats using pup’s meal kibble, having pup earn one of their meal portions this way several times a week. Don’t grab out of pup’s food bowl though, measure pup’s meal into a baggie and use that as treats. Depending on the level of pup’s aggression and severity of the bites, I would also desensitize pup to wearing a basket muzzle and drag leash while you are home to ensure it doesn’t get caught on anything. With those safety measures in place, you can calmly enforce commands like Out and Off when pup isn’t listening, to further build respect and trust through your consistency with following through. When pup doesn’t obey, calmly pick up the end of the leash and swiftly move pup out of the area or off the couch for example. When pup obeys willingly, a good basket muzzle should have holes and allow pup to open their mouth inside while wearing, so you can slip pup a treat through the muzzle too. You want pup to learn that biting isn’t an acceptable way to get their way, but that you mean what you say and that you are calm and consistent at the same time – so pup doesn’t have to be afraid but does need to listen. To introduce the muzzle, first place it on the ground and sprinkle his meal kibble around it. Do this until he is comfortable eating around it. Next, when he is comfortable with it being on the floor with food, hold it up and reward him with a piece of kibble every time he touches or sniffs it in your hand. Feed him his whole meal this way. Practice this until he is comfortable touching it. Next, hold a treat inside of it through the muzzle’s holes, so that he has to poke his face into it to get the treat. As he gets comfortable doing that, gradually hold the treat further down into the muzzle, so that he has to poke his face all the way into the muzzle to get the treat. Practice until he is comfortable having his face in it. Next, feed several treats in a row through the muzzle’s holes while he holds his face in the muzzle for longer. Practice this until he can hold his face in it for at least ten seconds while being fed treats. Next, when he can hold his face in the muzzle for ten seconds while remaining calm, while his face is in the muzzle move the muzzle’s buckles together briefly, then feed him a treat through the muzzle. Practice this until he is not bothered by the buckles moving back and forth. Next, while he is wearing the muzzle buckle it and unbuckle it briefly, then feed a treat. As he gets comfortable with this step, gradually keep the muzzle buckled for longer and longer while feeding treats through the muzzle occasionally. Next, gradually increase how long he wears the muzzle for and decrease how often you give him a treat, until he can calmly wear the muzzle for at least an hour without receiving treats more than two treats during that hour.

Once pup trusts your son, then having him calmly give pup commands for pup to work for treats and kibble, take pup on heeling walks, and teach pup fun new things can help develop both trust and respect for him further. Finally, provide boundaries for pup since there is aggression – fearful dogs also benefit from boundaries too; things like pup not being allowed on your lap unless invited and with the rule that they must get off of that and furniture as soon as they are told (and if they won’t use that drag leash and don’t allow them on there at all until their aggression improves). Not petting pup if they nudge or bark or are pushy for the attention. Not feeding pup when they demand it, but having pup do a couple commands and wait politely first. If pup is being rude, require some obedience and manners before giving them what they want. Doing so can effect pup’s overall attitude, and thus aggression level. Best of luck training, Caitlin Crittenden
