does anyone have a saint bernard? i am thinking about adopting one from woman who's son has left for college. she works all day and doesn't have the time to spend with the dog. i know they are large dogs, and my grocery bill will surely go up. just curious on how their temperment is with kids, (generally speaking of course) and other dogs. i do have a 2 acre fenced in yard, so when we were not at home, he would be able to roam and not have ot be tied up. my kids are 6 and 10. i work during the day but my husband works 2nd shift, so the dog would only be alone for about 3 hours daily. the lady said he is house trained, 8 years old. any comments?
