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.

Snuggle Jacket

This jacket is a little big on my pointer mix but she is a long and skinny weird mutt dog. We use this when it gets a little chilly out as she will shiver on her walks. But keeps her warm and she look so cute in it.

Great Jacket

Used to send our dog out and take her on walks. Easy on/off and makes her time outside comfortable.

overall fit and design is top notch . love the color and the reflective strips. however, i thought it was fleeced lined? just the neck area. my dog is short haired! i love everything except i thought it would be fleece throughout the coat and warmer for my dog! get the one up if you want warmth

The best

My dog Moody loves this jacket. It’s warm and soft and fits her perfect. Her measurements are 12” long back, 9” neck and 14” around the chest. She often wears the puffy vest with it.
