La pattuglia dei dobermann al servizio della legge

I remember this made-for-tv film as a kid. I was 7 when this came out, and in 2nd grade. Doberman's scared me then. But as a dog owner I can't help but wonder if the writers thought this one through. What high end department store chain used dogs to guard their merchandise? Was this even a real scenario? I'm curious because even my well-trained service dogs are not left alone running around in our house all night unsupervised. They get into things and sometimes make messes. I can't imagine a high end store using such a service, when most stores lose merchandise to shoplifting regularly (it's called "shrinkage") and take that into account when setting their prices. And that is during the day when they are opened for business. So as an adult I find this scenario ridiculous.
