Tried? As in - failed? Did the big dog lunge through the glass and eat them, or did you shoot them? I guess it doesn't make much difference. Either way, the whole glass needs to be replaced. The paperwork after an incident like that can be very time consuming.
But worth it.
They smashed the door glass with a big rock, then got surprised by someone coming into the parking lot and took off. Luckily, we had mirror tint on the glass, it was the only thing that held the glass in place. The alarm did not go off, as they had not entered the building. I was able to get the glass replaced yesterday and got a quote from the alarm company to upgrade the system to include glass break sensors. Thank goodness they did not get our new computers, one was still in the box with those convenient little carry handles. Yikes!
