This past weekend, I went to NYC so my cousin watched Hiro for me. I was going to put Hiro's collar on him but it didn't fit! I've used it since he was a puppy. Looks like I'll have to upgrade his collar. The only time I put Hiro's collar on him is when someone else is watching him, in case he runs off. When I take Hiro for walks, I don't put on his collar.
Before my NYC trip, I took off the ID tag and I hooked it to his harness with a split ring. I guess it fell off some time this weekend because when I came home yesterday, it was gone. =( I ordered him a Collar Tag from Boomerang Pet Tags after good reviews. Now I just need to get him a new collar. =)
