My neutered dog still humps other dogs. What can I do to stop it?

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.

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?

No, there is nothing wrong with the surgery. Dogs hump for other reasons like dominance behavior, play behavior or excitement. I suggest you refer to this article linked below: ( https://www.aspca.org/pet-care/dog-care/common-dog-behavior-issues/mounting-and-masturbation )

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.

Humping is not only a sexual behavior but it also a dominance behavior. It is most likely that she is trying to assert her dominance over the other dogs. This is a link to an article that may answer more of your questions: https://www.whole-dog-journal.com/issues/7_3/features/Mounting-and-Dominance_5615-1.html My recommendation is to get an in-home professional dog trainer to help you. Trying to correct this behavior can be dangerous if you don't know what you are doing. Hope this helps. Best wishes.

Has anything changed in the household? New people? New pets? Babies who started crawling/walking? Construction? Guests? Change of furniture? Changed schedules of routine? Etc.. Sometimes when there is some type of change it can strike up this behavior because they are anxious and trying to figure out what to do with themselves. They can also do it if they are trying to portray dominance. You can tell him "no" and take his toy away. If there is a particular toy that he likes to hump, I would get rid of it. You can also give him a calming chew like composure and a calming collar like adaptil. I hope this helps!

Dogs can still hump things even after being neutered because they have learned that it feels good. When you see him getting ready to hump something, immediate distract him with another toy, or ask him to perform a basis command you have taught him. That will get his attention away from humping, and gives him an alternative behavior to perform.
