I bought this harness for each of my 30 lb Tollers a few years ago and still love them. I like how they provide free range of movement in the shoulder, are light weight and still look new after years of use. We have a new puppy in the house and I'm writing the review as I'm picking out a new Perfect Fit harness for him! I also have the Ruffwear Front Range harness that I like for longer hiking adventures, but this is my go-to for everyday walks and hanging out around town (when there is not a pandemic).
