I'm looking for a bit of advice when it comes to selecting our next dog. I have owned dogs in the past such as a working line American Bulldog and Bullmastiff and want to get some considered opinion on the pro's and cons between getting a work capable Rottweiler or Dane/Mastiff/Arab cross that will likely come from hunting lines. It will be coming into a home where it will be the only dog with young teenage kids. In short I have never owned a dog that comes from the breeds that occupy the very top positions of breeds considered the most intelligent of which the Rottweiler does. What am I dealing with on this front? Would the Rottweiler be on a completely different level when it came to trainability and general interactions?
Any insightful commentary from people that have had exposure to both would be appreciated.
