i no exactly what you mean, when me the mrs and the kids go to bed, and you have a Rottweiler bullmastiff cross at the end of you bed, and a bullterrier and an American bullterrier sleeping down stairs, we all sleep very well in our house, the best alarm money can buy, and they would all give there life for me, and definitely the kids, in a blink of an eye, would be lost with out them.
