Review on Casual Canine Polyester Snowbaby 16 Inch by Megan Anderson

Very soft and fluffy and cute but smaller than recommended for the breed. I have a young pug that is not yet a year old, so it is still very slim. Small is recommended for pugs but I still ordered small/medium as I wanted to give her room to grow and sit comfortably. It ties under her arms and releases the Velcro so she doesn't have to strain while playing. I have to return it for a larger size but I'm not sure if a different size on medium would do. However, it seems crazy to order a large one. What would lab technicians or Saint Bernards wear?
