I use the velcro harnesses. I don't like colars for walking due to concern of neck injuries. I got this really cute red bandana one at
Designer dog harness, small dog harness, dog walking harness. - Girls. I had lots of problems with some harnesses knotting her hair and this is one that seems to work OK.
I also love using a denim vest with a ring for a lead. They make some precious ones and my YT seems to like that the best. I bought the "honolulu" for my sister's YT for Christmas this year. It is much cuter than it is on the website. My YT has the "boca". I think you have to scroll down to see them and can click to enlarge the image. I found mine at
Escape Proof Dog Harness Vests and they have matching leads as well. This vest keeps her hair from matting.
