Didn't want to hijack the other thread about male humping castrated male :) I am familiar with this idea, but have always been puzzled because my castrated dog humps an uncastrated dog :) I thought that it was just one of those things until a friend's GSD (also castrated) also humped the same dog. These two dogs hadn't met before and the reaction was almost instantaneous :) My friend was horrified, as her dog 'doesn't do things like that' :D - well, neither does mine, apart from doing it to this one dog (it's a ten year old choc lab). Any suggestions ?

The dog may be sick and have a sore that is weeping and the smell could cause this interest, it could be something more deepseated and of a hormonal nature.

This has been going on for at least a year - we only see the dog at most once a week. It seems in quite good condition, so it may be, as you say, something hormonal. I don't know the owner very well, so it's difficult to say anything :(

It is not a sexual desire but more of a dominant nature. A dominant dog/bitch will try to assert themselves as pack leader and this is one way of doing it. Nothing wrong with it if it doesnt lead to fighting or you could stop it if it gets too annoying.

I think its a hormonal thing.  My boy has the same reaction with a castrated black lab we know that he has with a bitch in season - chattering teeth, drooling, etc and he will happily mount him.  This has only happened since the dog was castrated and that's the only dog he does it too.  Although there may be some dominance thing in it, I doubt thats the main cause.  This dog obviously smells like an in season bitch to him.

That is probably something know as Feminisation syndrome that effects castrated males, can be treated but cost mega pennies for the tablets, if you only have one dog you can get away with it but if you have intact males to it can cause a good deal of trouble.

I would like to mention that not ALL dogs suffer from feminisation syndrome when castrated; my two certainly did not and no dog would ever have dreamed of trying to hump them.  Humping is not just sexual, or dominance but can just be excitement; bitches do it, dogs do it if you let em!

I had a male entire foster for a couple of weeks who started humping my entire dog all the time - both were 5 ish.  It was purely dominance and lack of socialisation with the foster (his body language when not humping was all wrong) - which my entire dog put up with.  My neutered male stayed at my parents - he would not put up with such behaviour and made that clear.

My entire dog, once he twigged on, played the foster at his own game and started to mount him.  After a very sticky patch appeared on the foster's back, the foster no longer mounted my dog.  Foster was neutered and when off to live happily in his new home.

Just to add, the humping and the conclusion between two entire dogs occurred without a single fight between them.

I watch wild dogs program years ago now. and every time the older ones went hunting and came back again
they would all humb each other even females would humb each other. so the fella said they did this to rank themselfs,
and who is pack leader.

Daisy, my neutered male Cocker Spaniel Jim (James T Kirk) has, to my shock, taken a liking to my newest male dog - an unneutered lost dog at least three times as big as Jim.  Jim continually tries to mount Spook.  Spook gets tired of this, so digs holes in the back yard he can lay down in so that his rump is not available to Jim!

Meanwhile, I yelll out to Jim, "Knock that off JIm. Leave Spook alone."

Jim, as if he has learned English with me (I talk to all the animals in complete sentences - and one time while talking to someone on a cell phone while I was out back - she noted with surprise that when I talked to the dogs, they barked back as if they understood what I was saying!  Well, no surprise to me- experience has taught me that dogs and cats are far more intelligent than they seem on face value.)

Sooo,. the way I stop that embarrassing fiasco is to say:

"Jim, leave Spook alone.  Knock that off."

Jiim climbs off, and that nonsense behavior ceases....

so long as Jim knows I am watching him.

My bitch keeps humping our other bitch, why would this be?

im sure that it is a dominance thing?
