Truffles?? No luck?

[Tamalak]

I lead a pig around on a leash in Lichenwold (white forest biome) for the better part of an hour today. He followed me and did nothing else. He has truffle snout 10. Am I doing something wrong?? Does anyone else have luck finding truffles?

10 is almost as good as nothing

I found a few black. 2 pretty much after an hour of pulling a pig along
