My dog is not fat yet I found this a little tight. Might need one size bigger.

UPDATE:Our trip went great and my little dog was super warm the entire time. The temperature ranged from 10'-30'F with strong winds and snow and ice. The hood stayed up the entire time, even in the wind, and the water merely rolled off the coat. I couldn't be happier with this purchase!!!

I purchased this coat in an XS to take my 5lbs Chihuahua to Eastern Europe in the winter. I'm super impressed with this little coat and am confident she will be warm while wearing it with a sweater underneath. We've already worn it around town and are stopped constantly to be told how adorable she looks! The fur on the hood is of excellent quality and my favorite thing is that the hood stays up keeping her little head warm! The arms of the coat cover her legs about halfway down and the length of the coat goes all the way to her tushy. The fabric is of high quality and appears to be water and wind resistant. The little pocket on the back is an actual functioning pocket. The only slight negatives are that the coat is a darker beige than shown in the picture and the neck area is a little snug. This is a great coat for the price!

I love that its warm and thick and long-sleeved

Love this coat! I've found most coats aren't long enough especially for super cold weather. This is the perfect length- someone even stopped us on our walk and asked if it was a custom coat! Great for blocking out wind and water resistant. I put a small t-shirt on underneath and my dogs was warm and happy! It is not very stretchy so be sure to check the measurements before ordering. The hood can also be taken off. Highly suggest this coat!

We have an old Maltese. This coat truly helps to keep him warm. It repels water pretty well but we have more snow than rain. The hood is removable which was important for us. Highly recommend.
