I made a similar pattern tutorial years ago and after many questions and comments decided to update it :) You’ll find full pattern photos, instructions, and measurement charts to make this sweater for ANY size dog, using ANY hook, ANY yarn and ANY crochet technique you like! It’s easy enough for beginners and works up in a snap!
