We are going to get a new puppy. She will either be an english mastiff (which we are familiar with) or we are considering a mixed English mastiff and Bloodhound puppy. We know a lot about the mastiffs, but not a lot about bloodhounds. We live on acreage (12.5) and it wil;l have free roam. Is there anything we need to know possibly about this mix or the bloodhound portion that we should be concerned about. Any help would be greatly appreciated.
