Ruffwear Singletrack Hydration Pack (size M)

We used it for a year and loved it. It's very low profile and doesn't get in the way of the dog adventuring/moving around. The side pockets fit these ruffwear water bottles - https://ruffwear.com/products/small-collapsible-water-bladder or you can buy off brand ones and they fit just fine too. This is a size Medium which fits dogs with a chest girth of 27-32inches. Currently $90 on amazon!
