Don't forget, there are no out of the box ready dogs, unless you want to spend many thousands getting a fully trained one. It takes time and consistent training to make a good dog that does what you want no matter what the breed. After you gt the pup you train, train, train for the results you want, if you don't know how to train you find someone that does or you buy references that tell you how to train the the results you want. I don't even know what to make of this,
(Is it possible to hunt (boar, deer, bear, mouse) with a single scent hound) unless it is a typo. Your profile says you are in Brazil. Are there even bear in Brazil and on the chance you meant moose instead of mouse are there moose in Brazil. I could be wrong but I don't think so.
