i have just come back from my friends today and she is at her wits end and i said i would ask on hear to see if anyone has had the same problem, she has a 15 month old dog and a 5 year old bitch now the 15month old male dog, is infatuated with this 5 year old bitch to the point of the bitch moves and he is mounting her, she walks across the floor and he is screaming and mounting her, the bitch has in the last few days turned on him marking him and he still is going for her to mount her, my friend has tried training discs on him and a water pistol and a shaker bottle, she has kept him on a lead which has been attached to her belt so he goes where my friend goes ,
she has had the bitch at the vets to check her out and everything is normal she is not due a season for another 4 months, but it is now getting to the bitch and she is starting to want to stop in her  crate more times than come out and be accosted by this rampant young male, she does not want the male to be castrated as she shows him, just wondering if anyone had over come the situation and if you did how.

thanks in advance

Is she having a phantom pregnancy? That can sometimes make a dog mount. Though it sounds like he is just at the stage where his hormones are on high. He should outgrow it. Could the vet not give him the drug that mimics castration? Sorry, can't remember the name off-hand. It sometimes calms a dog down, but not always. It's not a problem I've had, but then I don't usually keep males (I have one just now, and I'm not sure he realises he is male :D )

Get her checked for an infection it  can send males wild

15 months is quite late on for the first signs of rampant sexual behaviour - and such determined mounting too - so I'm wondering if the bitch is coming into season regardless of when she's actually due. Certainly, both my 16 month old dog and his brother are tremendous lads for the laydees if said laydees are coming into, or actually in, season. Otherwise they're happier humping each other. :rolleyes: 

As your friend has already had a vet check and all seems fine with her bitch, regardless as to whether there may be a season on the horizon or not, I would not tolerate this unwanted behaviour from the male dog, if I told him no and he continued to harrass the bitch he would be in a different room, behind a dog gate until he did as I told him.

His owners should have verbal control of him even if the bitch was in season, if he will not listen to a stay or no, then he needs to be seperted until he will do as he is told.  It is not fair on the bitch, I would not leave them together without supervision whatever the reason for his behaviour.

The bitch needs to feel safe in her own home and he needs to listen to his owner above and beyond his calls of nature. ;-)

just come from her house and i think she may of cracked the problem well not her , her daughter, the daughter was sitting with the bitch and the male tried to mount her the daughter said off and he ignored her so she scruffed him, and looked him in the eye growled at him and just shook him ever so slightly he had a flamin heart attack and has so far for the last hour he has left her alone

:-D  Well not exactly a verbal command, but if it got through to him........... but now they need to use verbal commands, if he even sniffs her again the daughter needs to give a very stern NO!  So does the mother and anyone else in the house otherwise he may only obey the daughter through fear of another growl and scruff and no-one else.

Glad that they have taken control of the situation and their bitch can now live in peace. :-)

He should outgrow it

Don't hold your breath ! :rolleyes:  My 10 year old dog is driving us crazy at the moment with his excessive mounting :rolleyes: he's completely obsessed with our younger dog (also male) as well as us !  We've tried everything to stop him - verbal commands do work, but only for a nano second. As soon as he gets off he's on again :rolleyes:
Does anyone know if a hormone imbalance would cause such excessive behaviour ?  I'm wondering whether to ask the vet to do a blood test to see if there's an underlying reason. 
He's not been castrated but had the 'mimic' injection some years ago but it didn't make any difference at all :rolleyes:

he has not been mounting the little dog for the last 3 days after being constantly nagged to get off, no and leave now, everyone in her family has been going at him constantly, and today she phoned me to tell me they where both playing chase each other in the garden today he chasing her and then screaming in delight when she chased him, they where lying asleep in front of her aga as she was on the phone , but i told her not to think he won't go back to his old way to keep a check on him.

Ahhh.............. well done, looks like a nice happy Christmas all round, he just needed a little guidance that's all. ;-)
