We are getting a female rotweiler puppy and I understand that their nature varies from lovable to extremely ferocious. We actually need a good guard dog for the house but am worried if our 2 children (2 1/2 years and 8 months) may be safe around the dog. We have had a lot of dogs (ranging from alsatian, doberman, etc.) as household pets always having at least 2 at a time but the rotweiler will be a new breed for the first time in the house.
