It was hard to figure out the fit for Flossie, because she has a slight body and small waist but is longer and tall. I sent in my measurements and got a recommendation for size. It fits her pretty good, but it's as small as it will go at the waist. She is kind of squirrely about new things (and life in general), but she does love her coat! We've had a lot of snow this year so far and she loves to go out and play. It stays on pretty good even when her friend, Glinda, is attacking her and rolling around with her. It keeps her warm--no more shivering. She can blast in and out the doggy door no problem. It keeps her warm in her crate when she is in the car or at the agility arena. There's no way to add a picture to show how beautiful she looks, but she does loves her coat!
