Gracie has her collars. But I only put them on when I let her go outside to do her business in the morning just in case something happens. When I walk her I put on her harness and attached to her harness are her Tags. She has one with her name and address on the front and in the back it has my name, home phone number and my cell phone # and the other is her rabies tag. Even though Gracie is microchipped I feel much better if she has her tags with her just in case.
