Fall Clothes for Small Dogs: Boo’s Closet, Sweater Weather Edition

The sweater comes back out.

The definitive Boo image is a teddy-bear face looking out of a tiny hood, and fall is when that hood came back out. Bay Area evenings turn cool and foggy early, and Boo’s closet followed the weather: the orange t-shirt through the warm months, then the hoodie at the first cold snap. Fall clothes for small dogs are that moment, the week the dog is suddenly glad to see the sweater again, and this page is about reading it right and having the right light layer ready.

It is a short list on purpose. Coats, boots, which dogs need a layer at all, and how to measure are on the winter page. The Halloween costume and the Thanksgiving outfit have their own pages. This page is the layer in between: the hoodie, the flannel, the first sweater, and the one piece of fall gear that is not clothing at all.

When should a small dog start wearing a sweater?

When the dog tells you, and in fall it usually tells you on the evening walk first. A small dog that trotted out happily all summer and now hesitates at the door, shivers at the curb, or hurries home is asking for a layer; a dog that walks, sniffs, and takes treats as usual is dressed right in nothing. Some dogs get there in September and some never do, and the winter page covers which is which. The first few weeks of fall are about watching the dog, not the forecast.

The fall layers, in the order they come out

None of these were Boo’s; they are the picks we think he would have loved, chosen today for a small dog in a cool fall.

1. The hoodie. The Boo garment. A fleece-lined hoodie with a pocket is the first thing out of the drawer in fall and the thing a small dog wears most days until the real cold. This one had close to eighteen thousand reviews, the most of any hoodie our search turned up, and at that count the chart has been tested on every shape of small dog. The hood is for the photo; most dogs wear it down. The soft fleece dog hoodie for small dogs.

2. The fleece turtleneck, three of them. The light layer for the first cool week, before the hoodie: thin, quick to dry after a foggy walk, and easy to pull on. The winter page builds its whole wardrobe on top of this one, and fall is when it starts earning its keep. Fitwarm’s fleece turtleneck three-pack.

3. The flannel. For the pumpkin patch. A cotton plaid shirt with real buttons is not warm, exactly, but it is the fall photo on a crisp afternoon, and it layers over the turtleneck when the afternoon turns. Four hundred reviews. Paiaite’s plaid cotton dog shirt.

4. The cable-knit sweater, two of them. The first real sweater of the year, and the one that stays in rotation through Thanksgiving. A two-pack in green and brown, twelve hundred reviews, and the green one does St. Patrick’s Day in March. The cable-knit dog sweater two-pack, green and brown.

5. The fall bandana, two of them. For the dog that is not ready for a layer and the owner who wants the leaf-pile photo anyway. Pumpkins and leaves on one side, plaid on the other. The fall dog bandana two-pack, small.

The walk that is suddenly dark at five

The clocks go back and the evening walk is in the dark for the next four months. A small dog in a brown sweater on a dark sidewalk is invisible to a driver, which makes a light the most important fall purchase on this page.

6. The light-up collar. A rechargeable LED band that goes around the neck over the regular collar, visible from a block away, and it charges from a USB cable like a phone. Seventeen thousand reviews, and the small size fits a Pomeranian. BSEEN’s rechargeable LED dog collar.

7. The reflective harness. The other half of being seen: a padded no-pull harness with reflective strips, which catches headlights at every angle a collar does not, and is the right thing to clip a leash to on a dark walk anyway. More reviews than any other small-dog harness we looked at, by a distance. rabbitgoo’s reflective no-pull harness, small.

When the winter coat takes over

The hoodie and the sweater carry a small dog through fall, and the day you need a real jacket yourself is the day the dog needs the winter coat, which that page covers along with boots and the measuring guide. Whether the dog likes any of this is its own question, and the first wet week of the season sends you back to the spring page’s raincoat.

Boo’s year-round wardrobe is in Boo’s Closet, and the year-round view of it, season by season, is on the seasons hub.

Frequently Asked Questions

When should a small dog start wearing a sweater in fall?

When the dog shows you: hesitating at the door, shivering at the curb, or hurrying home on the evening walk. Some small dogs get there in September and some never need a layer at all. No thermometer reading decides it.

What should a small dog wear in fall?

A light fleece or a hoodie for cool mornings and evenings, a flannel or a light knit sweater as the season turns, and a bandana for the dog that is not ready for a layer. A light-up collar or a reflective harness for the evening walk once the clocks go back.

Do dogs need a light for night walks?

A small dog in a dark sweater on a dark sidewalk is hard for a driver to see, so yes: a rechargeable LED collar or a reflective harness makes the dog visible from a block away, and it is the cheapest piece of fall gear with the biggest payoff.
