I have two Chilly Dog sweaters for Shelby: a cream cable knit and a pink-and-gray one. And honestly, their job in our house is pretty simple.
They are coonhound pajamas.
They are warm — noticeably warmer than our Wilderdog Fleece Jacket — they fit Shelby well, they are easy to pull on, and she looks ridiculously cute in them. I just do not really use them as outdoor gear.
Quick Verdict
Overall, I am fairly meh on the Chilly Dog sweaters as practical outdoor dog clothing, but I like them much more as warm indoor sweaters. They are genuinely cozy, wash well and look adorable. The trade-off is exactly what you would expect from a knitted sweater: ours stretch, pill and snag, and once you take them outdoors they get wet and dirty.
Would I buy another? Probably. Not because I think it is the ultimate technical dog coat, but because apparently I am the sort of person who buys her coonhound cute pajamas.
Are Chilly Dog Sweaters Actually Warm?
Yes. This is the part I would give them real credit for.
In my experience, Shelby’s Chilly Dog sweaters are warmer than the Wilderdog Fleece Jacket. When she is chilly indoors, they provide a useful amount of warmth without needing to put her into a proper outdoor coat.
Chilly Dog currently sells a large range of hand-knit wool and wool/alpaca sweaters, including cable-knit designs. The exact fiber content varies by design, so check the individual sweater rather than assuming they are all identical.
Why I Keep Ours Indoors
Could a dog physically wear one outside? Of course. Chilly Dog markets its sweaters for cold-weather wear. But that is not how I use ours.
Knitted sweaters and woodland coonhounds are not an especially sensible combination. Ours get wet, pick up dirt and snag. Over time they have also stretched and pilled. None of that makes them bad sweaters; it just makes them much less useful to me outdoors than purpose-built dog gear.
So ours stay inside. Shelby gets to be warm and adorable, and I do not have to spend a walk wondering what branch she is about to attach herself to.
Fit and Ease of Use
The fit on Shelby is good. I have no real complaints there, and they are easy to put on.
That matters for something I am using casually around the house. If she starts feeling chilly, I can pull one on without turning it into a whole production.
How Do They Wash?
Surprisingly well. Despite the pilling and stretching we have seen with wear, I have been happy with how ours wash.
Chilly Dog’s current care instructions for many of its wool and wool/alpaca sweaters are machine wash cold and lay flat to dry. I would still check the care instructions for the exact design you own.
Durability: This Is Where the Knit Shows
Our sweaters have stretched, pilled and snagged. That is the main reason I mentally put them in a different category from something like a technical fleece or insulated dog coat.
For lounging around the house? Fine. For squeezing through brush, getting muddy and generally doing coonhound things? I have much better options.
Chilly Dog vs Wilderdog Fleece
This comparison is actually interesting because both have ended up being used as Shelby pajamas at various points.
The Chilly Dog sweater is warmer in my experience. The Wilderdog Fleece Jacket, however, is much more outdoor-appropriate: it washes brilliantly, handles normal dog mess better and is less vulnerable to the problems of a knitted sweater.
If I wanted something cozy for Shelby inside, I would choose the Chilly Dog. If I needed a fleece that could reasonably transition outdoors, I would choose the Wilderdog — although for deliberate cold-weather layering I still prefer the Ruffwear Climate Changer.
The Best Thing About Them
They look adorable.
There. That is the serious professional assessment.
There are dog products I own because they solve an important problem, and there are dog products I own because Shelby looks exceptionally cute in a cable-knit sweater. These fall firmly into the second category — with the useful bonus that they are genuinely warm.
Would I Buy Another Chilly Dog Sweater?
Probably.
Is that because I desperately need another one? No. Is it because they are cute and I am apparently incapable of resisting coonhound knitwear? Yes.
If you want serious outdoor winter protection, start with my dog coat comparison instead. But if your dog gets chilly around the house and you want a warm sweater that also happens to make them look absurdly sweet, I understand the appeal.
Bottom Line
The Chilly Dog sweaters are warmer than I expected, fit Shelby well, are easy to use and wash nicely. But ours also stretch, pill and snag, and I do not consider them practical outdoor gear for the way my dogs live.
For us, they have found their perfect niche: warm, adorable, indoor coonhound pajamas.
