I love Rottweilers because they are extremely intelligent, stubborn, independent, self assured, mischeavous and very affectionate.
Because of all the above traits, they are entertaining to say the least. They are constantly trying to get away with things when they're young, but are one of the most obedient breeds around when spoken to in a calm voice.
When raised correctly they are very calm around other dogs and good with children.
Oh and they like to sit on your lap, lay across your body when you're sleeping and give heaps of kisses.
