the sleeping doggie

My dog, Robin, almost 3 months old is now sleeping under the sofa I'm sitting on. He is very calm and like an angel WHEN HE SLEEPS. Once he wakes up, something like a...naughty fairy or a cute little monster runs about wildly, breaking me out in a cold sweat.

I don't have a child, if I had, how!? or what could I!? I felt dizzy. I respect all 'motherly love' going through tough (also happy?) times. I had dogs but no responsibility when they were babies. So this time the first.

A few days ago suddenly he screamed, he bit into a crate and his canine teeth were caught, one of them was broken and oozing with blood. Soon I realized he was trying to unlock the door. He was outside the crate at that time, and copied me.

He is okay, still sleeping soundly.
