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.

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.

Wonderful Product. Wonderful Company.

I love Ruffwear products. The quality is outstanding. I have never been disappointed, and that includes the Fernie jacket. I bought one for both my pointer mix (S) and terrier mix (XS). Items fit true to size, the colors are beautiful, and my dogs don't mind wearing them. They also seem very warm. Love the fleece. I also have to shout out to the staff at Ruffwear. Everyone I've ever worked with have been absolutely wonderful. Unfortunately, it's rare these days to experience such exceptional customer service, which is why I have to make a note of it. Ruffwear will continue to be my go to for this simple fact alone.

Great sleeping jacket

My Labrador, Walker, does not like being cold at night when we camp. This jacket is the perfect solution for him after a full day in the river watching my husband flyfishing.

Fernie jacket

Love the Fernie jacket keeps the chest and belly of both my dogs nice and warm. I do wish the sleeves were more roomy.
