This is the kind of harness Tatum has...
I just did a quick search for a "step-in dog harness" and got this picture. I don't remember where I ordered it. Maybe you can find this kind in stores, I'm not sure. What I like about it is that they just step into it and it closes at their back - instead of having to put their head through a little loop. Just easier - and doesn't mess up her topknot!
