fighting female guinea pigs

Question
I have three sisters from a pet shop iv had them a couple of months now and quite often i hear and see one of them attcking the other 2 iv had to separate her and put her with a different female all together she still doing the same. Iv taken her back to the pet shop where i got her from and the owner wasn't much help he basically just said to take her back and he will re sell her in a week or so, another pet shop told me to get her neutered but i don't really want to risk it.

please help im running out of ideas im thinking of taking her to and adoption part of a shop

Answer
neutering will do absolutely nothing, just a waste of money and risks the healt of your piggy. sometimes you get an aggressive pig like that, if they grew up together then bonding is pointless as they already have bonded and so it is more down to personality or enviroment.

the only suggestion i can give other than keeping the guinea pig on its own is increasing the size of their living space, if a pig feels confined then they do tend to be more aggressive with each other.

best of luck.
