Unfortunately, 90% of baby boar trios don't make it to adulthood together.
Your options depends on how much space you have got, how our rescue and vet access is.
- living alongside: possible but not ideal for a sociable piggy. it depends on being able to provide him with constant interaction and stimulation through the bars.
- boar dating: many of our recommended rescues will allow you to bring your boy for dating under expert supervision at the rescue, so he can choose for character compatibility, ideally with a laid-back adult boar if the has been badly bullied. Another baby could mean a repeat of the bullying once the youngster is hitting the teenage hormones himself.
- neutering: only recommended if you are thinking about pairing up with a sow or two after a 6 weeks post op wait.
You will need to find either a general vet with plenty of guinea pig neutering experiencing (usually by neutering for a rescue) or an exotics vet with practice in small furries operations in order to minimise the risk of especially post-op complications. I have got the surprise daughter of a suppoesedly safe over 5 weeks post op boar, just to prove the point about the 6 weeks wait, which is practised by good standard rescues anyway and seems to the be the safe waiting period.
On the plus side: cross gender bondings are the most stable of all piggy pairings once initial acceptance has happened (again, ideally at a rescue under expert supervision, so you know that things will work out when you bring a new mate or two home).
We have got UK good standard piggy savvy rescue and vet locators on the top bar, but may also be able to provide links for rescues and vets in other countries.
