Guinea pig dominance

Question
Hi! My name is Kayla and i just recently bought a girlfriend for my male guinea pig Lucky,and for no reason he nips her but she never does anything,but should i still be nerviest?

Thanks for your time :)

Answer
Hi Kayla

Firstly, do you intend to have the girl have babies? Guinea pigs breed very easily so be careful.

Its normal for there to be a bit of scuffle between 2 pigs new to each other but if any injury, however minor is caused, please consider separating and letting me know the details.
