He is 2 and a half months old and I rescued him because his previous owner couldn't keep him with any other pigs because of his aggresson. He's lovely with me. Maybe he just didnt like his old cage mates!
He is still a bit too young for a neutering operation as his testicles have not yet descended.
You have got two options:
- boar dating at a good rescue under expert supervision, which means that you come home with a companion only if acceptance has happened. By using our recommended rescues, we can guarantee that you are in safe and experienced hands and that any new guinea pigs are quarantined and healthy. This way you minimise the risks of ending up with two boars that do not get on and always have the rescue to fall back on if things go wrong between the boys.
- neutering, which means research for either a good general vet with plenty of experience in guinea pig neutering or an exotics vet with practice in small furries ops in order to keep the risk of post-op complications down. You also have to factor in a full 6 weeks post-op wait before he is 100% safe to go with sows. The baby in my avatar is the legacy of a supposedly safe over 5 weeks post-op boar (not one of mine). This is not the only case I have come across.
Boar dating is the cheaper and quicker route, whereas neutering takes longer, is more expensive and comes with the operation risk, but you have the long term advantage that cross gender pairings are the most stable of all piggy bonds.
I only have got neutered boars in my house; most of them live with 1-5 sows each. Because of the presence of sows I can't risk having a full boar accidentally meeting them. Neutering does nothing to change the temperament and or behaviour; all it takes away is the ability to make babies.
