Say a "bad" person finds your dog - plans to keep it. A collar can be taken off and thrown away. A microchip, generally, is forever. Unless they are a sick, sick person - there's no way they can hide the microchip.
I agree with you on that. I just know that Zoe my heart dog ran off one day when there were fireworks on the fourth of July and she had no collar on. She did have a microchip though. The person who found her didn't know about microchips. I was lucky to have been driving around and see Zoe on this person's front porch. I know if she had a collar/tag on she would have been returned to me sooner. She was gone for a whole week.
