Green Fernie jacket

I love it, and (more importantly) so does my dog! She was much warmer this winter after getting her the Fernie, and it doesn't seem to slow her down when she runs full speed through the woods. Giving 4 stars because it is a thinner/lighter jacket than I was expecting. Otherwise, just what she needed. And the green color is beautiful.

Fernie jacket for 10 pound beast

We have other Ruffwear products -- all good. This jacket works well on our 10 pound all white havaton who loves water, wet and mud.

Carson loves his jacket

This jacket is easy to put on. Having a Standard Poodle coats can be hard to fit due to their “big” chests. This coat fits great. Love it.

Good quality

Jacket is well made, with nice material. I used my dog’s chest measurement to pick the size like the chart says, and it fit him very well there. Only complaint is that it’s not cut for a hound - the tummy part doesn’t quite fit close enough.
