New Guinea Pig Problems! Help!

[ShadoSunset]

I recently got a new guinea pig. He is a baby. I have only ever had my one older guinea pig male and decided that he needed a friend. My new guinea pig keeps getting humped and pushed around by my older guinea pig. I don't know if this is normal or not. I don't know if I should post a photo or video of what is happening. Please help!

Humping is part of normal dominance behaviour (even in same sex pairs). I have attached some links below which explain what is normal.

Have you checked the sex of your new piggy to confirm that it is a Male?

This is completely normal dominance behaviour and your older piggy is asserting his position as top pig. It should settle down within a couple of weeks. Please see this thread for more information on dominance displays Bonding and Interaction: Illustrated social behaviours and bonding dynamics

Hi and welcome!

As long as your two boys have plenty of space so that your much more agile baby can escape any time it really, then I would not worry.

I would however recommend that you create a little safe space that only the little one can get into whenever he's had enough, as recommended in our bonding guide, which also contains adult boar/baby boar bonding advice and a video (see links in previous posts).
The refuge should have two exits so the baby is also free to leave his sanctuary anytime. A small tunnel or a cardboard box filled with soft hay would be ideal.
Young babies are generally not at risk of an attack but incessant humping from their new uncle boar can become too much.
