Mo, rotties if raised from puppies can be big giant babies that love everyone. Some rotties are babies to their owners and then behave aggressive
toward strangers that visit. It's kind of tricky Mo, you can have protection with a rottie, but at the same time you don't want the rottie to bite your friends or family members.
It's best to ask a dog trainer or seek advise from your local animal shelter.
I hope I was able to help a bit.
