Got to ask yourself, do you really sleep well at night knowing that dog is sleeping in your childs bedroom? Not me bud because you do not really know the predictability of that animal but you may think you do which may be a tragedy.
Yes, yes I do. I trust a well trained dog over a person anyday. They do what they've been trained to do, and what will please their owner, and defend the pack at all costs. People 'think' and are completely unpredictable.
When i joined the army, I had top find a home for my dog, a Rott/doberman mix. Now my 76 yr old 4'11" grandmother has a guard dog/companion that weighs as much as she does. And the dogs mionds without a leash, sleeps next to her bed, and has even gotten the Jehovah's(Sp?) Witnesses to stop coming by (The dog almost never barks, and will suprise you when she walks out of the shadows unannounced). My grandma is the type of person that has always been afraid of larger dogs, and always had small toy breeds that a house cat could beatup. I let her take care of my dog for one weekend, and haven't gotten her back in over two years!
