So my sister purchased a sow several months ago we all loved that guinea so much that we recently purchased a bore at our last show. Because the bore was too young and therefore inactive and couldnt get our sow pregnant we put them together for a split secant to clean the cages .so gees what happened. We are about 75% positive that the sow is pregnant the only problem is that my sister keeps reading that if you are going to get a guinea pregnant you want to do it at the latest of 8 months or ells the hip boons fuse and it would spell the end for the guinea. Our sow is well past 11 months old and my sister is now in her room crying about losing her beloved Izzy. What I want to know is if this hole hip fusing thing is true and if so is there any way of saving her guinea pig?
