Humping has all kinds of communication uses in dogs. Obviously, it can be sexual, it can be domimance related, and it can be used to iniate play, particularly in puppies. Most humping in dogs is no big deal, unless the humpee takes offense. Males are the most common participants, but not exclusively. Lots of breeders find that their females will form humping chains during estrous. And many females will do dominance mounting. In my experience, I have found that play related humping seems to be a mostly male baby puppy thing. My guess is that it has something to do with being excited, and stimulated, and having the natural reaction to that be a happy sexual feeling 
Most puppies seem to grow out of it pretty quickly.
I would say that Caesar is totally normal 
Andrea's post pretty much sums it up. Your boy is perfectly normal and I suspect the humping is simply an expression of dominance or assertiveness. Caeser is trying to tell the other males that he is the boss. The same with Beta.
Also, humping or an unusual interest in the penis area can sometimes be a sign of an irritation. Sometimes a urinary tract issue or sometimes maybe a grain of sand in the shaft. This is rare but it can happen.
Is Cairo a sexy boy?
Why doesnt he hump me and just humps Caesar and my boyfriend? Not that I have humping envy, just curious.
Is this a sign of a sexy dog?
HAHAHAHA!!! Take him to a doghouse of ill repute!!!
"humping envy"…hahaha!!! That's funny.
Thanks for the laugh.
So was Caesar the weird one? He never humped anything as a puppy and Cairo is the crazy hump player!!

oh, I know, it is silly isnt it…..
I really miss my little girl........she was sooooo cudly compared to the boys....
Our Chance is going on 15 weeks and he has "humped" a few things. His favorite thing to hump is my back 
I will be sitting on the couch and he will worm himself behind me and try to hump my back. Of course I stop it immediately. I even went to the extent to purchase him a "hump doll" from the store. He would rather hump the cat or me instead
It has concerned me..The last thing I want is a dog who humps in public. Thats a real conversation starter lol
I believe that this is one instance where negative reinforcement might be helpful. That's the way dogs teach each other to give them space, maybe it would work with humans too. Any one else have any thoughts on using negative reinforcement in this situation?
Senji is 11 years old and was "fixed" at 6 months. He never really humped anyone, but first thing in the morning after he wakes up, he has his morning "boner". He just kind of air humps for a few seconds and then licks the exposed part of his penis.
Vegas, I think you are talking about punishment…negative reinforcement is actually a different principle, that I won't bore everyone by getting into. But yes, you could use punishment here, I suppose. It would depend on what you and the dog viewed as punishment though...I probably just re-direct the pups attention, and find a more appropriate way to play.
A squirt bottle might be an appropriate punishment here.
Querk humped one of our male friends' arms (or tried to, we saw when he got the look in his eye, and distracted him). He did it for a few weeks when he was little. He is intact, and he grew out of it. But he has never been a really "testosteroni" kind of dog. He only humps now when the girls are in heat. Has to be 'his' girls, and it has to be at the peak of estrous. We have a special humpy blanket for him, so he doesn't violate the couch cushions

Hahahaaa!!! LOL :o This thread is so funny - reminds me of morning radio host talk on a rock-n-roll station here in Detroit. Can we get any more descriptive?
Sorry, I don't have anything to contribute, but I find this thread entertaining. Thanks! 
When my dog wakes up from sleeping he sometimes humps air and walks while doing it. It is so strange, like he just cant help it. Must be some good dreams:p
Anyone who has seen this just cracks up.
Other than that he humps my boyfriends dog but that is a way for him to get her to play and she really doesnt mind she (Phoebe the frenchie) just kinda stands there and looks around.
I dont know what to make of any of it, I am just glad he does not do it in public

Squiggy does this too, I have never heard of it. He doesnt "expose" him self, but he does look around with a look that says "huh? what is going on?" or it could be "darn it, who woke me up?"
he doesnt do it all the time, but when he does it is so funny. Air humping :p
