I'm worried because my brother has Harleys tag in Arizona (when Harley came to live with me in TX he forgot to send it). But, I did get her microchipped and she wears that tag. I need to call him today and make sure he gets home with the tag next Saturday. Bella wears her tag on her harness too. I just got them both the step in kind of leash, in one piece. Where do you put the tag in that situation?
