Random Extreme Aggressive Behavior

[Aprilbean]

I have a female Guinea pig, April, who is around a year and a half old. Shes always been super sweet, I spend at least an hour a day with her, most of the time she's passed out sleeping next to me but the issue is is that I can pet her, and shel be loving it, rolling over on her side and putting, but god forbid if I accidentally touch her stomach especially in the dark when she can't see, her personality instantly changes violently she shel aggressively attack my hand, latch on and sometimes draw blood, and then when I pull away and yell "ow" she gets even more mad and chatters her teeth at me, I've taken her to the vet two times now to make sure she wasn't sick and they said she was fine, I think what the problem is is that she thinks my hand is trying to assert dominance, if that makes sense. She hates other animals, We had to stop allowing her and our rabbit run around together in the living room because she would mount him dominantly and attack him if he went near her, the cats are even scared of her. She's also only sweet to me, I'm the only one she will lay down with and sleep on, April and I have a seriously great bond together to the point where I almost consider her a human haha.I guess my real question is is if anyone else has this problem and if there's anything I can do to convince her I'm not trying to dominate her when I accidentally touch her belly

Many guinea pigs don't like to be touched on the belly. As you are very close; she is drawing that line very firmly. But it is not matter of her trying to dominate you her, just to make that particular point. There are a few piggies that are not into other piggies. Many of them have been separated early and been kept apart from others of their kind, so they have never learned to socialise properly (which is much more differentiated than assumed, as recent research has found) and to see themselves as guinea pigs. She has obviously also never learned how to integrate into a group/hierarchy and is therefore trying to run the roost around her.

Thank you ! That makes a lot of sense, I bought her at pet smart a year ago so she probably didn't have any solid bonding time with other pigs and it probably wasn't a pleasant experience for her anyways,
