Female specimens are used because the odor of truffles remembers the hormones released by the male.

The method of collection is similar, it must be stopped before it will eat the truffles and award, but due to the size of the pig some quite expensive expedient is necessary.
First of all it can be used until to a certain size, beyond which it becomes difficult to transport and manageable, serving means larger than the simple car trunk, and it should be tied with a leash to a thick rope, considering, finally, that in some cases it may be dangerous to humans attacking it, even fatally.
The environment is heavily deteriorated by this animal, because with the nose tends to rummage in the ground, sometimes causing irreparable damage.
Finally, it is evident how it is not sufficient a dog -house and a garden to house it, but it requires the appropriate spaces, a significant amount of food, not to mention the smell that it emanates.
