I had a rottweiler (he got stollen) & when he was a puppy he was box trained (he'd sleep in his box ect.), when he was about 9 mounths old, I put myself in a BIG box & started to call him... when he found me he was so mad that I was in a box he riped the bax apart. when he finally could smell my finger thru a whole he licked my finger & went out of control ripping up this box untill I was safely out of the box...... I remeber one time I took him down to the river around where I live... I was only 11 & I was splashing in the water... he came running in the water (he was tied up he chewed thru his rope), he got in the water grabed me by my shirt & drug me back to the river bank... Now if that isn't love I don't know what is... he got stollen 5 years ago... & I have another rottie that when ever I ride my horses he gets mad becauses I'll yell at them or something, & he'll start barking his head off.... he broke out of the house once came running to me & stood infront of me growling at my horse..... I love my rottie & I'd do anything for him
