Hello I’m a new member who created this account to get some advice on my 2 male guinea pigs behaviour. My two guinea pigs are 2 to 2 and a half years old (with them been rescues not 100% sure) my younger guinea pig Jonathon has been mounting and dominating my older guinea pig Biggie. I would normally worry about this but I noticed yesterday that there was a small tear in Biggies ear this has healed and does not cause him any pain so it must have been a few weeks or months ago. I have been advised to keep an eye on it and if it become violent and aggressive to separate them but I was wondering if I could get a more widespread opinion. Neither of them have been castrated but I have never had a problem with them mounting each other before. I hope someone can give me some advice. Thank you for reading and if you leave some advice then thanks also. I am open for questions if anyone needs to learn more.

Hi!

Adult boars can occasionally suffer from a short but strong testosterone spike. If this becomes too much for the other, then a short 2 days separation with a divider can usually do the trick to allow tempers to calm down without breaking the bond, followed by a re-introduction on neutral ground.
If the ear gash was an accidental misjudge swipe or bite, the boars will know this and go back together. If there was a full=on fight, then it depends on how bad the grudge is. You should know pretty quickly. Have your oven gloves at the ready.

If the mounted boar is normally the leader then mounting can be a sign of a change in leadership. In adults and older piggies there can be an underlying health issue that causes this, so it is always good to close out a potential medical angle.
