My 17 month old intact male has a hernia, I don't believe in neutering/spaying at 6 months so I just plan to have it fixed whenever he's neutered. That said there is a risk that the intestine can drop down through it so I'd definitely have a vet look at it just to be safe but I think the risk is small.
