The 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.

Second Fernie

The Fernie has been the perfect sweater for my go everywhere chihuahua. It keeps her cozy in the San Francisco fog. We loved our first Fernie (green) so much that we ordered a second (orange). She gets so many compliments & people really notice the quality of the Fernie sweater. We’d love Ruffwear to make a charcoal or black version!

Warm & Snuggly Welshie

Being Welsh Terriers are never noted as breeds for sizing, this one was a bit tricky. Our boy Roo, it turns out, is right on the high end of one size and low end of another. Welshies have chests that are quite broad for their size but the small was enormous and sadly the beauty of this jacket was entirely lost on him. I re-ordered through Ruffwear directly for an XS and it fits him like a glove. One inch longer along the back and perhaps a bit more wiggle-room for his chest area (their fur is extremely thick) and front leg openings would have been ideal but other than that, he has gotten so many compliments. He has no problem doing what he loves best, running and jumping (and better still if a squirrel is around) in his new beautiful duds. His "mom" loves the easy on and off of that perfectly designed zipper it! Thank you Ruffwear from Roo & mom <3 L. Marrero Bronx, NY

Excellent jacket

Perfect for our 7 month old Lab. We live in upstate NY and it keeps her good and warm on long walks and allows for plenty of freedom of movement

Size inequality

I purchased these jackets for my daughter's dog. She is a small pit with a barrel chest,. We measured her chest size and ordered the right size. However, she swims in it, it's just way too long for her body. Perhaps they can ask for body length as well and make the products fit all body types?!


Hi Heather! Thank you for your feedback. Here is a link to our Fit Guide for the Fernie Jacket: If you scroll down to the "Product Dimensions" you can see the length and neck measurements for the various sizes. This is especially helpful if your dog falls between sizes! Feel free to reach out to us via email, or phone, 541-388-1821 if you would like further assistance.

Even fits a Pittie

I had the hardest time trying to find a jacket that could also be worn inside on cold days that could fit the peculiar build of a pitbull. Everything else I tried was either too long or he busted out of it like the Incredible Hulk. The fabric is a high quality sporty fleece with a nice side zipper that is away from his face so he can’t chew it off. Easy to wash too.
