My Yorkie is 13 weeks old now, and just received his rabies vaccine and was given a tag to wear. As of right now he hasn't been wearing a collar...just a harness when we used the leash. I am going to search the internet today to order him an identification tag. Does anyone have any place they'd recommend? My main question to everyone is how does your Yorkie wear these tags? Do you have a collar with these attached, then place the harness on as well if using a leash? Do you attached them to the harness? Do you leave a collar or harness on at all times? Thanks...my husband and I can't agree on what to do!
