I have 3 female Guinea pigs. I've have 2 together for a while and decided to get another female. I did the whole quarantine and proper introduction. They have been the the cage together for a day alittle for 2 days. One of my Guinea pigs keeps whinning everytime the new one comes close to her, occasionally nips at her and the other one wont stop rumble strutting at everyone now. There hadn't been any really serious fights that I've seen. The newer Guinea pig raises up on her back legs and fluffs her hair like a dog shaking off? I'm not sure they are getting along just yet? How long does this dominance dance usually last for ? And why does my one Guinea pig keep whinning ?
