I have a male dog that every time he is around any of my sisters dogs, he start to hump them and the worst is that they are all male dogs. I can not get him to stop, he continues doing it over and over and over. He can continue doing it for a long long long time, I want him to play with other dogs, but he just want to hump them. What is wrong with him, can any body helps me please?

Could be two reasons either to assert Dominance or high Libido...
"Rampant hormone on 4 legs" plenty about he is not abnormal.
Mine stills humps and he is three -not males tho, any female
willing or not he will assume the position.

I was told he would outgrow it, he has not, and he also lifts his leg over my females food bowls if they are left down.
Go figure that out! I would reccommend a cure if I had one,
but fresh out ideas myself I just correct when I see it,
and crate if it gets to boisterous.

Your dog doesn't have a screw loose. I would treat this as a dominance issue and either redirect or firmly correct my dog for it.

I would also rethink letting your dog "play" with other dogs. Sure, it would be nice, but this kind of behavior, with the wrong dog, could result in a dog fight. JMHO

He's showing you he should not be permitted to play with other dogs. Humping is typically a sign of dominance (especially if he's humping male dogs... trust me, he knows they aren't bitches). Humping is NOT despite what some veterinarians and many dog "behaviorists" will tell you, a sexual behavior.

Unless a male is trying to hump an in-season female, humping is a social behavior. (As an aside, urinating on other dogs, or on their food, bed or bowl, is also a sign of dominance.)

Continually allowing him to interact with other dogs is only going to encourage his dominant mindset, and set you up to have other behavioral issues down the road.
Additionally, he may some day try to hump a dog that doesn't feel like submitting.

Dog fights are nasty things. With a dog that feels so driven to dominate the dogs around him, it's best to keep him away.

ditto, Ditto, DITTO!! great post Alyssa.

This dog should not be allowed to continue this behavior, and if the only way to achieve that is complete isolation from other dogs (ESPECIALLY strange dogs with undetermined temperament), than that's what needs to be done. There are plenty of dogs who are easy going enough not to react to such persistently rude behavior, but in the event that you meet a dog who's not (I happen to have one), you'll have a dog fight in seconds.

Maybe a little re-directing is in order. Training aid possibility
I don't remember seeing this in the Leerburg catalog, maybe at petco or something.

There's a possibility thats not interactive enough though, if thats the case maybe this? Here Boy!

Alyssa- just two things wrt to your post, I am fully aware the reason he does the peeing over the bowls, I think the point, I was trying to make was to Mr Perez was that I had exhausted all reccommmended training methods to contain a similiar problem and that it was sometimes dominance related I just wanted to lighten the situation for the other owner, as it is not the easiest problem to diagnose,and sort out, as for it not being sexual behaviour, we shouldagree to disagree on that point, I know of many seasoned stud dogs that will mount almost any female that is either just had a season or coming into one, and simulate "humping " behaviour.At the time of writing this post I just did not feel like writing a "post mortem on humping", so did not elaborate on the details on my own dogs behaviour, he has a certfied dominance problem.
P.S. I personally would never allow my dog to hump dogs I do not know, he is doing this within my own pack! As for the other dog
the owner will have to work on this problem, and needs encouragement to find what is going to work for him and his dog,
and hopefully get it to some level he can manage it like I have with mine.IT NEVER GOES AWAY!!

Personally, I would not let my dog hump ANY dogs. (unless of course, I was actually breeding them)

As my dog's leader,I don't tolerate that behavior within my family pack. By allowing a dog to hump other pack members, I'm telling him that he's the boss. Not me.

Not allowed here, ever.
