Reece has a regular collar which he doesn't always wear. I use that and a regular leash when I take him out. I am having a hard time finding a harness small enough to fit him. I think I might have to get a cat one for him. I prefer harnesses on smaller dogs because they seem so delicate and if for some reason I had to yank the leash, I'd be afraid of hurting the little neck. Reece is excellent on a leash though so I doubt I'll ever have any problems with him on a regular collar.
