My best friends just got Duke a few sweatshirts from Casual Canine and they all have the hole for the D ring. The only problem I encounter with those sweatshirts is that they do not cut the portion under his belly so when he pees outside, the urine is stuck in his sweatshirt. I had to modify that after our first walk.
Also, it isn't as attractive, but Duke as a Puppia harnest vest so I sometimes would put a shirt on him then the vest outside to keep him warm.
