Hi

Ive read alot that rottweilers arent usually suited for first time owners and ive also read that boxers if commitment is put in to them are good as first dogs...but whats the difference between having each because of what ive read about these breeds is that they are both very energetic and need alot of exercise and also that they are both big dogs and can be stubborn...so why are rotties more difficult to have as first dogs and boxers not so much?

all answers are appreciated..thanks
