Your don't need to put a harness on your pup because this jacket has two clips for securing one or two leashes. I generally use two leashes when walking my 85 pound boy so that I can keep him from chasing the unexpected critters we encounter.
As an experienced tailor, I am pleased with this solidly constructed jacket that includes a zip pocket and reflective piping. The outer fabric layer is windproof and water repellant while the inner layer is smooth fleece.
Well worth the price.
