the poor dog probably triggered it gasping for air and trying to get out.
how about this, put the owners inside a vehicle with windows rolled up and secured from the outside so they cannot get out and see how long they last.
scumbags.
Why do you need to set an alarm when the security system is in the car?
I take my dog everywhere and leave ny windows mostly rolled down and never lock the car muchless set the alarm.
Hell, if I don't need my keys for a store membership tag, my keys are also hidden in the car also.
Try and get in, you will be surprised
