Introduced a baby guinea pig to older one

[Elizadriksne]

I've had a male guinea pig for 4 years now, been alone all this time but recently decided to get another one for company as I'm pregnant and won't have as much time to play with him anymore.
I got a male baby guinea pig.
When introducing them the older one constantly chases the baby one, licking his ass, nudges him and kind of does that thing where he fluffs up and purrs/gowls, seems nothing aggressive to me, never any fights or blood, and the baby one doesn't react much, like he tries to ignore it or walk away. I separate them and put them back together everyday but the older one is still the same, and its constant, doesnt want to leave the baby alone for a second, is this normal, dominance thing? Are they getting along?

@Elizadriksne Piggies are herd animals and so need to establish their position in the hierarchy. This is what you boys are doing, trying to determine who is 'top pig'.

You need to let them get on with it, even though it can be quite stressful to watch. Only separate if they start fighting and blood is drawn.

Are you introducing them on neutral ground?
