I am always pleased with the quality of RUFFWEAR products. They are Definitely made to last. My Doberman LOVES his “PJ’s”. He whines to let me know he wants them on. Then lifts each foot without my asking to put through the leg holes. Too cute.

love this coat!

it's the perfect weight for active dogs in the winter! Only complaint is the zipper sometimes starts to unzip.

Great quality

Awesome product. The quality is wonderful and it’s very easy to put on as the zipper is on the side. This jacket is also very easy to clean. We had it on our pup at the dog park this winter where it (of course) got super muddy and it held up to cleaning very well. Overall awesome jacket and will be buying more products from Ruffwear in the future!

Great jacket, needs adjustments

I bought this jacket after buying the Fernie Jacket & has the same issue; the material is great, it does keep my dog very warm and comfortable during our outings. My only issue is that the sleeves rubbed her skin raw, the abrasion on her skin during activity made it hard for her to continue wearing it. She’s got very short hair and if the sleeves could just be made a bit longer & more loose so that it gives the skin some breathing room. I have no other issues with it, perfect winter jacket for most dogs

It fits!

Great lighter-weight jacket for my 140 lb dog and it fits perfectly! I’ve never found a jacket that fits him this well because of his size but the XL is perfect. I love that the sleeves give a little extra coverage. It zips on/off easily too. I would give it 5 stars if I could put it in the dryer.
