Introductions introducing two males different sizes

This is the bible on introductions: https://guinea-pigs.livejournal.com/3002707.html

Do it when you've got a LOT of time to supervise them in the neutral area -- like several hours. Don't rush it.

How big a cage do you plan to put them in?

it's actually my friend doing it, she put them in a large open space & one is pulling out the others fur, any advice?

The link says, only separate if blood is drawn. Pulling fur doesn't count.

that's horrible~ he's being bullied and getting hurt why should she make him suffer?

Guinea pigs are wired to establish dominance. There'll always be a "top pig" in any cage. But they'll go through a period of chasing and nipping and humping and rumbling until one gives in and lets the other "win." You have to let them do this if you're going to have them live together.

If you separate them and put them back together again, they'll just start from scratch all over again. It's very stressful for them.

You have two choices -- let them work it out, or separate them and let them live alone. Guinea pigs are herd animals, and almost always do better with a buddy. But they have to get through that initial dominance dance first. I think it's kinder to let them sort things out and then have a pal to live with.

Horses do the same thing - prey animals that live in herds have to have A dominant one - that is super important to them.

When you introduce new horses to a herd, after they have had a chance to run the fence lines next to each other and squeal and act like idiots, then they get put in a pasture together. Well, guess what happens - they have to find their place in the herd. There's a lot of fake kicking, occasional mounting, squealing, and sometimes minor wounds. More than that and they should get pulled away - i.e. if blood were being drawn or serious injuries were going to occur.

It looks terrifying. It's not. And they would rather be in a herd than alone.
