Male dog humping spayed female

I've searched the forums first, but i can't find anything related to this. I have a male XL Bully 2y 9mo old. We have a female, spayed, xl bully at nearly 9 months old. Over the last 3 days, it's almost like the female has come in to season as the male is completely obsessed with trying to mate with her. She can't be in season because of course she's been payed - this was around 6 weeks or so ago now. I've read that sometimes when performing spaying, there can be bits of tissue etc that could still give off the 'in season' pheramones, but I really don't know what to do.   Any advice?

Hello and Yes, I'm afraid it can happen that when a female dog is speyed, some ovarian tissue is left behind.  Furthermore, it isn't always within the region of the ovaries - random hormone-creating tissue can sometimes occur in unrelated places around a female dogs' body, even when she has been properly speyed.  The second thing that can happen, is that males can get attached to humping for completely non-procreatary purposes and that the hormones aren't what's driving it.  I suspect that this may be even more likely if the two have been together before (the drive of habit).  Finally, male dogs sometimes have hormonal overdrives eg connected to the prostate gland which intensifies their drive to hump.  A useful thing to do might be to take both to the vets to discuss possible tests (the prostate gland can be felt, for example), in order to work out how best to approach this.  Please do let us know how you get on!

Sorry - I have reread this.  I will research and return.

Hello - yes, you mentioned that you'd read through the forums before posting (thankyou for doing that- we should start recommending it).  I remembered a previous article somewhere but it's actually in the blog.  If you type 'humping' into the search bar in the blog, then you might find this interesting.  As ever, ypur vet is the best port of call.  Please would you keep us in touch re: what happens next?

Thanks for the reply - i'll take a look at the blog :)
