I have a litter of Kune Kune's and have noticed one of the boys looks like he has a hernia, it has been getting bigger the last few days. I have felt around and it doesn't feel like a testicle like the other boys and i'm pretty sure it is a hernia. He appears to be in no pain at all and eats and runs around as much if not more than the others. What would be the advice for a pig destined as a pet??
