When you're not home does your dog still wear it's collar?

That is the first time I heard of this. I mean I can see how it is possible, but if your house is safe, it is rare it can happen. But I always keep my dog's collar on. Honestly, when you are gone is the most important time they should wear it. If something was to happen such as someone breaking into your home, a natural disaster where you cannot get your pet, or something like that happened, when someone finds your dog they know who to contact. When you are home, it is less likely (though still possible) for your dog to get out because you are around him. When you are out of the house, that is when most dogs escape and need their collars the most.
