Thank you very much guys.

I would like to know some other things...
The bull stays most of the time in a small place, the kitchen and sometimes we get him to the room to watch tv and we leave him alone to rxplore some places there. Is that a problem?

I mean, if he stays the most time of the day in the kitchen and then later we allow him to stays in other places of the house, will he feel the need better to be in the room than in the kitchen that is smaller?

Or should I only allow him to be in other places when he learn to do "the basic needs"(or should I say learn to "use the bathroom")?

Thanks again folks, you seem very kind! =)

Ps. Sorry my English, I do not speak English at all. Yet!
