I’m considering having my 3 1/2 year old boar neutered. He’s been living with one other boar since very little but he has sadly just passed. I’ve been speaking to some rescue shelters and some other experts about grouping and for his age. All suggested female companions due to young hormones or potential fighting with males in general.
How safe is it and at his age?
also any suggestions on possible groups or preferably pairs? Thanks
Hi and welcome
I am very sorry for your loss!
I have adopted several boars neutered at this age and know of successful ops even in much older boars. Here is our comprehensive guide to all questions around neutering:
Neutered / De-sexed Boars And Neutering Operations: Myths, Facts and Post-op Care
The biggest risk factor in adult boars is not so much age but overweight. Please check around the ribcage whether your boy is a good weight for his size or whether he could lose some.
Our weight guide tells you how in the chapter about 'heft':
Weight - Monitoring and Management
Crucial for operation success is finding a good operating vet, either a general vet with plenty of practice in boar neutering (often for a rescue) or an exotics vets with experience in small furries ops.
Here is our recommended vets locator. Please be aware that it is based on member feedback and not comprehensive:
Recommended Guinea Pig Vets
Rescue dating your boar 6 weeks after his op once his post-op safety wait ends (to allow the semen in tubes that lead to the penis to die off they are not removed) is the best way of ensuring a good match. A happy guinea pig bond always relies on mutual liking and character compatibility. Initial acceptance during the bonding process is the biggest hurdle in a cross gender bond. You can look at a single sow or a well-bonded sow pair.

However, you can also consider dating your boar at a good welfare standard rescue that offers this service with another boar of any age; again mutual liking and character compatibility comes before age. Adult boars can be bonded, especially in rescues that offer residential bonding (as explained the second link).
