Design by Crochet Parfait.
This adorable pet sweater comes with a size chart, so you can crochet this in basically any size that you need. It’s modeled on a teddy, but I’m sure it’ll be just a gorgeous on a puppy.
The pattern also comes with lots of photos showing the process from start to finish.
You will need a worsted weight yarn in two colors, an H and I crochet hook and three buttons.
