Help! new guinea pig mom.

[Iheartpiggies]

Hi everyone! I'm a brand new at this so I have lots of questions. I'd appreciate it if you guys could help me out. Please forgive the long story, theres a summary at the bottom if you want to skip over the sob story.

I recently adopted two piggies to which the animal adoption place wont answer any or my emails or phone calls. I've been trying to get more information from them (such as where they came from and and how old they were etc.) without luck. One is around 3 months old (approximately) and actually came home to me with ringworm. The other is now 4 months I think.

But now that shes all better I've been trying to introduce my two little girls together to be friendly but it has been anything but that.

Out of the two girls, one is clearly more dominant which I understand should be the case. However, the smaller of the two gets completely scarred when the bigger one comes by. I know that there may be the usually rumbling and butt sniffing and chasing, but my question is, how long should this go on for? The little one ends up urinating all over the place like a water gun out of her rear end! (Sorry for the graphic image). She does this every time shes scarred of the big one at her bum and the big one gets a face full. Does any one else's guineas do this? Can she get dehydrated from it or something? She does it many times throughout the day.

I've tried all the usual let the two meet in a mutual free range place and the clean the cage with vinegar and rearrange everything so that it feels like a different cage but all that really happens is the little one gets bullied. This behavior happens when they have free range time and when they are in the same cage. I've had them in the same cage for about a day now, they were kept separate before.

Will I just have to accept the fact that they will have to live in different cages? Or will they eventually get use to each other I just have to give it time? It hurts my heart to hear the baby crying but I know that its just one of those things I have to ignore so that they can eventually be friends.

Any advice would be great. Thanks!

Summary questions:
1- How long should the usual dominant/submissive behavior go on for when introducing guinea pigs?

2- Do you think I need to completely separate them?

Your problems are just simple dominance issues. Unless they are drawing blood, leave them alone to sort out their issues. It can take hours to days for one to submit to the other.

I have a piggy that sprays when the others move in for rear sniffies. She's just a nervous, traumatized sort of pig. She gets better all the time, but still sprays them occasionally.
