I have 2 kids 3 & 4 yrs old, my wife is 90 lbs. which is a potential problem with controlling the dog on a leash. I am considering a Rottweiler if it will make a good (safe for my family) pet. I had a boxer before so I am fully aware of what owning a boxer mean ( high energy est..) I'm just trying to weight the pros and cons to make sure I get the best dog (best fit) for my family. thanks in advance for your help.
