I presume he hasn't been neutered?

If not, then I think that basically explains it and it's likely to happen quite often through his periods of "heat".

Don't worry about it though, it is normal if the dog isn't neutered and your perhaps planning to breed him or something.
He's 100% bang on. It's just that time of the season isn't it?
