How to Cut a No-Sew Sweater Sleeve Dog Sweater

Getting the fit right is the secret to a sweater your dog will actually wear. Measure around the widest part of the chest and compare it to the sleeve. A thin dog suits the narrow cuff end, while a bigger chest needs the wider top of the sleeve. Cut the leg holes small first, since you can always make them bigger.
