oh my.. please research the breed more! You cannot just go out and get one!..you need to research them and if you can, spend some time around a full grown adult saint, they are a giant breed dog. It is not uncommon for males to reach over 150lbs, make sure you are ready for such a huge dog. with big dogs comes big responsibilities, bigger vet bills, bigger food bills, bigger everything, belive me i know! They really are a great breed, i am glad you are considering one, but please, PLEASE familiarize yourself with the breed, THEN think about getting one. There are hundreds of saint bernards, and other giant breeds, across the country, because their owners really wern't ready for such a big dog, and the dogs are the ones who have to suffer
