My Beagle rescue is very 'butch' she wees on 3 legs just like a male etc. Just lately she has taken to trying to hump the other female dogs but twice today they have turned on her. Unfortunately she received a leg bite in the last spat just now, although I have cleaned etc with hibiscrub, I will keep an eye on it but it is not too bad.

What makes a bitch act like this so much, is it a hormone deficiency or just her nature as I really need to stop this happening. Luckily I was right there today to stop things getting too heated but it obviously annoys the other bitches, so it must stop.
She does it to the boys as well but they quite like it !

Any advice would be great as they are normally such a happy bunch that really get on well and I need to stop anything like this that can disrupt the harmony.

My girl humps her bed when she gets frustrated, like when we are ignoring her or when one of us leaves the house.
When I tell her enough she then either acts like it was the bed doing it and jumps about and will bite it and shake it or she gets off and sits down but still slightly humping.

Thanks Jo, I wouldn't mind if it was her bed as that doesn't bite back, but it's obvious the other girls object quite strongly

my brooke ( bitch ) has been humping whispa , male gsd since she came into season lol he has told he off as well. little pomx frequently humps whispa and brooke if sh e gets a chance and also cocks her leg. I must say its only between my own dogs though.
I think its adominace thing however not sure if its because she is dominant or is trying to show she is while not being if that makes any sense. Hopefully one of our people with more behaviour knowledge will be here to tell us

Bitches can hump other dogs the same as dogs can. In past years we have had 3 in a row doing 'piggy backs'! We havnt had any do it for a while now...it doesnt usuallyy make any difference if they are entire or not.
It is  quite normal but the problems occur, if like in your case, the others get nasty.

With my lot,  humping goes along with seasons being due,  and during a season.

The neutered bitches do it too.

But in between seasons,  no humping.

Is there a chance she is coming into season?    

Now I don't think it is necessarily a dominance thing.  My old Bearded Collie did it when younger, and it was always due to excitement.  She's never had pups and has been spayed years back. 

I know when she was at her height of the humping era, she would come up to me when I was at the kitchen sink doing dishes, and she planted her paws on my shoulders and humped me.  She never did master the correct action though.  She bounced up and down like Tigger.  :-)

My guess is that it's a hormonal thing.

My five year old BC Fern  never misses an opportunity to hump me. She is a sweet girl and pretty low down in the pecking order here so I'm certain dominance is not an issue -don't believe in that anyway. But whenever my back is turned or I'm on my hands and knees scrubbing the floor,she creeps up , wraps her arms around me and she's off. Stopping to chat when out on walks, she 's behind me and ready for action. No joke when she's covered in mud. It isn't a huge problem. I just tell her to 'gerroff' and she does.

Many thanks for all your comments.
She had been used for breeding (BYB) was then abandoned and lived rough, then rescued and spayed, so no more seasons.
It may be excitement, she is not OTT dominant in fact she is happy to plod along doing what the others do.
I am just trying to avoid a nasty fight when one of the girls objects to being humped, as happened yesterday. On that occasion I was right there and able to stop it before too much damage, but dread to think if I was further away.
I know humping is a common occurrence but is there a hormone drug or something that can take the 'need' away to avoid it happening when it likely to cause trouble in the dogs pack.

It can be excitement, nerves, hormones, or illness (I've never seen an instance that I thought was about dominance): has she been checked out?  Every time I see this question I'm reminded of a lovely lab I met years ago with his owners, who informed me that he was stuck on lead because he had a systemic yeast infection.  That caused a LOT of humping - I can't recall now whether it was to him or from him, but I *think* it was him doing the humping which was why he had to stay on lead.

Many thanks Nikita, I will have a chat with my vet next week and see what she suggests. My Beagle is very nervous after her background but is not as bad as she was. She seems happier in the company of dogs rather than humans and I wonder if it is excitement to see the other dogs that brings it on. If there is something wrong with her I would never forgive myself if there was a bitch problem because I did nothing about it.

My girls hump each other when in season but at no other time. Just a hormonal thing I think.

To my surprise My 7 month old WFT Sophie who has just come into season for the first time has had a go at humping all three of my other dogs!

Perfectly usual.
