2. Hunter, a gorgeous and very well­-behaved retriever, was super comfortable wearing our size XL sweaters, but dogs come in many shapes and sizes! To ensure a well-­fitting sweater, compare your dog’s measurements to those shown on the schematics.
   While crochet is stretchy and will accommodate a range of sizes, you may want to adjust the pattern before beginning – perhaps making the Back of the sweater longer if your dog likes to be extra cozy or the neck bigger if your best friend is especially fluffy.
