Oh chattiesmom! Im so sorry this has happened to you! BUt i am also soooo happy nobody was hurt! It is a horrible thing to experiance (My mom experianced it.. twice).. Your post gave me goosebumps. (I am terrified of the thought of a fire and I am in tears right now)
I Still hate the idea of crating when not home. But i also hate the idea of her being out and hurting herself (Even though we have everything that is possible to dog proof, dog proofed) ..

to you and all your family
And

to your son for getting himself and your furbabies out in time
