Why does my male dog only hump me? Is it dominance or hormones?

He is at the age of puberty! The fastest way to stop puberty behavior is to have him neutered. He is young enough it can stop a lot of unwanted behaviors such as humping and urinated excessively by marking and lifting his leg. It will not help humping as a result of dominance. This how dogs show one another who is in charge. So if he is doing to it to some people and not others, then he is proving he is charge of them and does not respect (listen) to them. The best way to correct this is to encourage training sessions to make him obey and listen so he understands he is not in charge and that behavior is unacceptable.

This is not a sexual behavior, but likely a response to stress, anxiety or to assert his dominance. Correct the behavior immediately when you see it. Remove him from the dog with a stern "No" and offer a toy or task to distract him. Praise and reward him when he complies. If he persists, separate him until he settles down. Be firm and be consistent.

It is likely more a dominance behavior than a sexual one. Consider having him neutered to decrease testosterone levels. In the meantime, when he does it, push him off with a stern "No". Praise and reward him when he complies. If he persists, place him in another room until he settles down.

Humping is not only a sexual behavior, it can also be a dominance behavior, a stress response, etc. Any new changes lately - new pet in the home, any major changes in his routine or in the house?

It's hard to say why Duke might be doing this with only one specific dog. Humping in dogs is often associated with frustration, over-excitement, or can be an attempt to solicit attention or play in some cases. It would help to be able to observe the dogs interacting in order to make a better guess at why he does this. If it's causing a problem, the best option would be to simply separate Duke from this dog when you are at your friend's house, or keep him on-leash so that he can't bother the other dog. You could also try giving him something special to chew on when he is there, such as a bully stick or rawhide, to help keep him busy.

The best thing you can do for him right now to help correct this behavior is to get him neutered. As he grows and starts to produce more testosterone, he can start to become more aggressive and dominant as male dogs are prone to these behaviors. Once they learn the behavior, it can be difficult to train them out of it. But if you spay him now before he has a chance to fully develop these tendencies, it will keep further behavior problems from worsening. It should also stop the humping behavior. After his neuter, if he still seems like he is having issues with aggression, you will want to enroll him in a training course or work with a behaviorist to help you establish yourself as the one in charge. Training courses are there to teach us how to respond to our pets as much as they are to train our pets to respond to us. Aggression is something you want to tackle early before they h ave a chance to become routine behaviors.

At 4 months and 13 days old he can be neutered. The humping could also be an attempt to establish dominance. Do not let him hump, tell him "NO" and then remove him to his sleeping place. Schedule an appointment for having him neutered.
