Button up, Furbaby! Holding two strands of yarn together and One piece design makes this a quick and simple sweater to make for your four-legged kids. Plus no leg holes for easy on and off. Buttons are attached within the crochet and having 3 allows for adjustment in size on the Belly band. For Small pattern is worked using a K hook and Simply Soft Yarn. For Medium sized dogs, a L Hook is used and Red Heart Super Saver yarn. As, although both yarns are deemed “Worsted Weight” the Simply Soft is thinner. When worked in the yarns and hooks reccommended the small size is 11 inches around the neck and 13 1/2 inchs from the top of the cuff to the bottom edge. Size Medium is 14inches around the neck and 16 inches from the top of the cuff to the bottom edge. The small fits my Miniature Dachshund (about 10 lbs.) The Medium fits my Standard Dachshund, (about 22 lbs.) The sweater is constructed with a ribbed cuff around the neck to allow for stretchability for sizing and your pets comfort. Also, gussests are added at the shoulders and ribs to conform to the shape of your dog. Pattern instructions include both a large flower, small flower and dog bone for decorating as you choose.
