For those who lock their dog boxes...
When do you lock your dog box? Immediately after loading the dog(s) and unlock when you reach your destination? Only when you are parking your vehicle and leaving the dogs inside and unattended for a period of time? Something else?
I lock my box only when my truck will be parked and unattended for a period of time. I NEVER lock the box when I load the dogs, I'm afraid that if involved in an accident I wouldn't be able to get the dogs out in an extreme emergency.
What do you guys/gals do?
