What do I do?

[Four-piggies]

Okay so I have 3 male Guinea pigs named cosmo,tony, and creek (nephew named them btw) and they got along fine for a year and a half when I got them and now cosmo and creek don’t get along as well they don’t fight but creek will chase some and chatter his teeth at him. What do I do?

We will require more information about their relationship.
Chasing and chattering is a normal dominance behaviour so in that respect is ok if they are still getting on and want to be together BUT unfortunately three boars together usually do find things difficult and can normally have problems in their relationship at some point.

Do they have plenty of space - for three boars that is a cage of 300x100cm? (This is so they each have one square metre of territory)
Lots of hides which all have two exits?

If they aren’t getting on, their relationship is failing, one is getting stressed and/or depressed (signs such as losing weight through not being allowed to eat, being chased away from food, being chased away from beds so not allowed to rest), potentially the dominance is spilling over into bullying, then it’s most likely they will end up needing to be separated into a functioning pair and a single piggy.

If this is beyond normal dominance now, then you can carry out a trial separation to see if the two which do get on are happier just to be together without the third. Whichever piggy is separated out his going to be upset, but it isn’t the ‘bully’s’ reaction you watch at separation, its always the bullied

Yes they have the space they need. It’s only one that will chase the other around and it seemed pretty normal to me because they weren’t harming each other and they all eat pretty well but I was sitting with them and the one was hiding and then the other came around and chased him and didn’t want to fight back so that’s when I got concerned and I’m kinda nervous. I had 4 in the beginning and they were just paid in 2s but one died and I gave it about 2 weeks before I put them all 3 together and I started the slow bonding process and it worked and they were fine until now.

It’s good they’ve been ok until now but it doesn’t mean it will last and this is the issue with trios - one day it can just go wrong.
If one is consistently being chased it may mean they they just don’t like each other and cannot stay together. A bullied piggy often won’t fight back to begin with but can suddenly snap when they have had enough.
It’s something you need to keep an eye on and keep in mind that if a fight does break out, you may end up with three single piggies rather than a pair and a single

Slow bonding doesn’t really work with boars, it’s not until they are permanently put together and not separated again that they start to form a relationship. Any introduction and separation stops the bonding and means they start again from the beginning every time.

The slow bonding started when maybe a year ago they’ve been together two weeks after the other died. But I also just moved and I feel like that had something to do with it.

If you have moved house in the last couple of days/weeks then any change of environment will cause them to reestablish their relationship. In a well bonded pair this will result in a few days of increased dominance and then things will settle. In an unstable pair or trio (or more), the change in environment can cause deeper problems to come to the surface.
