When i got my pigs i got them sperately and once i got them i did a quarantine to much sure one wasn't sick and all. After when i put them together they kept mounting and teeth chattering (hard) they wont even stop chasing each other! :( One of them is 1 year and 5 months now the other is 1 year and 2 months. i got the older one from a petstore i asked if theirs any pigs at the back and the person said yes (the older one was gonna go to a kill shelter) i got him home and waited 2 weeks for adjustments and taming. they have been pouncing at each and doing dominance behaviors. they urinating Here is a Video:

Sorry I'm new to guinea pigs but I'm sure someone will be along soon to offer advice.

Good luck!
Hi there. The run you are using is very small. Boars need lots of space for them to get on. With guinea pigs one is the piggy in charge. They will show this by chasing, mounting and humping. This is all totally normal. The other pig will run away and squeal. The squeal is to let the boss piggy know he is not trying to be in charge. It does not sound nice but it is normal for guinea pigs. Please read these links as they will explain more,

The boys don't have much space to get away form each other in your bonding pen, but the behaviour in the video is not worrying at all and very normal. please keep an eye on them and see whether they will settle down together. The most critical phase is usually when they wake up after their first nap together. Have oven gloves ready in case you need to separate if they start fighting.

All the best! Bonding is always a rather nerve-wracking experience, especially the first time round!
