Could a pit bull beat up rootweiler?

It is not possible to accurately predict the outcome of a fight between two dogs of different breeds, as there are many factors involved, such as the individual temperament and training of each dog. Both pit bulls and Rottweilers are strong, muscular breeds that can be aggressive if not properly socialized and trained. However, it is important to remember that dog aggression is not a breed-specific trait, and any dog can become aggressive if it is mistreated or neglected.
