My top choice for a choke free harness is Susan Lanci's quick release step in harness design. We love them! They are super soft, durable, washable, customizable (tons of colors and crystal options) and made in the USA, which is important to me. They also come in half sizes and you can order different sizes to check fitment and return them for free. We LOVE them! Best wishes!!!
You can take a look below at the website where we order ours, though there are many places to order them from.
