You could get your boar neutered? Alot of rescues neuter guinea pigs for bonding purposes. If i was you id have a look and find a guinea pig you like, alot of rescues will bond them for you to check they get on. If you have a look here there are oftne piggies needing home and you could get soe advice from a rescue there. Its a bunny site but most of the rescues are very experienced with piggies too
