When you are crocheting for your pet, you need to consider especially his/her comfort in first place. So think of this sweater pattern as a stitch pattern, this is only an example of how it fits and looks on my dog. It is made by using front post double crochet and back post double crochet techniques. Therefore I can say it is a very easy pattern and just adjust your measurements according to your pet's sizes.
