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.

Toasty Warm “sweater” Jacket

Brady loves the Fernie Jacket! We ask him if he wants his “sweater” when he is cold, and he jumps right up. It’s easy to put on, and is very durable.

Nice sweaters

Great quality. Good fit and easy to get on. Only drawback is that they are way too long for my dogs. I just applied Velcro and roll them up to fit after they are zipped.

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
