i tried the buddy belt and it didnt fit right, was either too big or too small. wetnoseboutique was very nice and have a good return policy.
i use a puppia step in, this kind does not bother there neck at all. the over the head puppia can bother the neck more. but i am happy with the step in kind.
also for a really pretty harness, i Love the susan Lanci one, the kind that clips, not the velcro kind. they are expensive but gorgeous! i got the kind with the flowers and crystals, forgot then name of the style. its the newest style. so so pretty
