I have two new male guinea pigs... Ever since they came home and I put them in their cage the one called teddy started rubbing himself up against the other (caramel) and purring, not rumbling.
Although the vet said their testicles haven't fully developed yet however teddy loves humping caramel, especially in the face! And yes.. He does ejaculate afterwards...
Caramel has lately been rumble strutting a lot to teddy which I know both the humping and rumble strutting between two males is a dominance thing however... When caramel rumble struts to teddy his anus pulsates and he pushes back into teddy... He also lets teddy lick that area whilst he is rumbling...
I have checked him and I am sure he is a male..
My question is has anybody else had this? Is it just dominance, are they gay or should inbe worried that caramel is not in fact a boy lol.
Thank you in advance.

Hi and welcome!

Rumblestrutting is mild dominance behaviour, as is mounting - across both genders. Some boars do it daily throughout their lives. Any configuration of guinea pigs has to establish or re-establish a hierarchy in new territory, so you always get dominance behaviour. Please be aware that boars go through a hormonal period in their pre-adolescence between 4-14 months old when it decides whether they are character compatible or not.

Mine are doing that too, I think they just have to establish who's in charge since they've only just arrived in their new home. Keep an eye to make sure they're not fighting, and that neither of them is being bullied but it should be fine :) x

I'm sure after a few days things will settle. New surroundings, weather and other piggies around can all set them off but usually just lasts a few days x

Ok well just an update. They have not settled down, caramel rumblestrutts most of the day, every single day and teddy will chase him but there is no fighting which is good. However just lately caramel has been trying to hump teddy so I'm sure this is just a dominance thing.
