The Ruffwear Fernie is a technical sweater for dogs, designed for everyday adventures from the trail to town. Advanced sweater-knit fabric offers the look of a sweater with a fleece interior, offering the warmth and performance of a fleece jacket. This sweater can be worn alone, or layered underneath other Ruffwear coats for additional warmth. Our “Sleeved” style jacket provides full coverage for maximum warmth. A convenient zipper on the left side of the jacket allows for a high-performance fit.

Awesome Warm Layer for Chilly Mornings in the High Desert

Handsome Henry loves his orange fleece. On cool desert nights he sleeps like a baby in his cozy crate with his comfy warm fleece on. Great fleece.

Top product

The sweater is very nice, our basenji loves it! The first one we ordered was way too big, so be careful with the sizing and make sure you measure your pet well, before ordering. But without any problems from the Ruffwear company we've changed it for a smaller one. The process was extremely fast and smooth, so we'd like to really send our appreciation to the company as they showed extreme regard towards us. Thank you! To all those considering buying this product, would definitely recommend to do so :)

Zipper wore out

Your Fermi dog sweater is the best. The cut of the garment fits my dogs body so well. It has been the best looking sweater I have seen also. The only issue was the zipper losing teeth and the not working anymore but because of your guarantee you replaced it with a new sweater so problem solved. My dog used the sweater everyday last Winter and the zipper wore out.
