I have a 15 ob shih tzu. Would this fit him if I got an extra large? The reviews are saying they run small
Answer by Sandy • Dec 16, 2025
I have a 13lb Shih Tzu & had a large but it’s tight. I am now buying an xlarge
Are the straps adjustable so it can be loosened or tightened as a long haired dog's hair length changes?
Answer by • Dec 13, 2021
The vest harness has some room for adjustment but the surface of the hook-n-loop fastener needs to cover at least 80% in order to be secure.
Is this made in america
Answer by • Oct 26, 2021
This coat is made in Vietnam.
Did the Mountaineer iI coat/vest come with the harness or does the harness have to be ordered separately?
Answer by • Nov 02, 2021
This harness doubles as a fleece vest as the harness is part of the vest.

A handsome little fellow
As mentioned in previous reviews, one must watch the sizing. Winston is a 12.5 lb Pom and is wearing an XL. It fits him perfectly and makes him look quite dapper

fits so well
I love this, I think it looks super warm, and Rory does not seem to mind it. It is so convenient that they are both harness and jacket!!

Runs extremely small
Love the color and the material. Waterproof outside, and super soft fleece inside. My dog is a 30lb aussiedoodle, and I got an XL because I read reviews saying sizes

Great and multifunctional
I love that I can keep my pup warm without suffocating him with a harness and a jacket. This jacket has both !

sizing
Although Mikey's girth measured 18inches, and this description said 18.9, it was too small for him. I've ordered the extra large, and hope this will do.
