The Stretch Fleece Vest was made after our popular fleece vest. Unlike the regular fleece vest, the Stretch Fleece Vest is super stretchy and fits dogs up to 100+ lbs. We made it so versatile that it evenfits a mini pig. Usually our sizes tend to run small for dogs under 35 lbs, but not for our Stretch Fleece Vest! This is our first attempt to offer bigger sizings for larger dog breeds due to popular demand. If your furry friend has a unique body shape and you have a hard time finding a comfortable soft fleece vest with proper sizing, our stretch fleece vest is definitely right for you.
