Best Dog Collars for Small Dogs: Fit, Comfort & Safety

The best dog collars for small dogs are light, soft and adjustable, with hardware that won't give way when your little one zooms around the yard. Our favorite is the Channing Dog Collar, an ultra-soft navy velvet collar in a slim 5/8-inch width for tiny necks. Our second choice is the Katelin Dog Collar, a waterproof pink and yellow ombre collar made for summer splashing.

If your toy breed has a delicate neck or a history of coughing, pair that everyday collar with a harness for walks.

What to Look for in the Best Dog Collar for Small Dogs

Little dogs come in every shape and personality, from couch-loving Chihuahuas to zippy Jack Russells, but a few features suit them all. For a broader look at the basics, our guide to good dog collars covers the fundamentals.

A Lightweight, Soft Collar for Small Dogs

A heavy collar on a tiny neck is like wearing a winter scarf in July. Look for slim, light materials with a soft finish so the collar doesn't rub, drag or weigh your dog down during a long day of supervising the mail carrier.

Adjustable Sizing for Small Dog Collars

Small dogs come in a huge range of neck sizes, and puppies keep growing. With an adjustable collar, you can dial in a snug fit now and let it out later. Our XS fits necks from 8 to 12 inches, and if your dog is more medium than mini, our Medium covers 13 to 19 inches in a 1-inch width.

Sturdy Hardware on a Small Dog Collar

Fashion is fun, but the buckle and D-ring still need to feel solid, click shut securely and stay put when your dog shakes, scratches or tears around the yard.

The Best Collar Types for Small Breeds

For most small dogs, a well-fitted flat collar is the comfy everyday choice for ID tags. If your little escape artist slips out of everything, a martingale can help, though it needs a careful fit and supervision while worn. Our guide to different types of dog collars explains the rest.

When a Small Dog Needs a Harness

Toy and small breeds like Yorkshire Terriers, Pomeranians and Toy Poodles are prone to tracheal collapse (when the windpipe weakens and flattens), and pressure on the neck can make their coughing worse, so vets often recommend switching these dogs from a collar to a harness. Clip the leash to the harness for walks and take it off once you're home, and keep a light collar on for ID. If your small dog coughs, honks or tugs hard on walks, have a chat with your vet.

The Best Small Dog Collar for Summer

Summer calls for a collar that dries fast and cleans up in a flash, which is where Katelin comes in. It's waterproof, mud proof and quick-drying, with a pink and yellow ombre as sunny as a beach day, so you can rinse off sand or a mystery puddle in no time.

Adding a Little Style With Small Dog Collars

Once comfort and fit are covered, the fun part begins! Channing's soft navy velvet looks dressed-up even on an ordinary trip around the block, and you'll find velvet in lots of other shades across our range.

Fitting and Everyday Safety for Small Dog Collars

Even the cutest collar needs a little everyday care, so keep these habits in mind:

• Check the fit regularly, so the collar sits securely without squeezing. Our guide to tightening a dog collar has the steps.
• Keep an eye on your dog while they wear it, since a collar can get tangled during play or in a crate.
• Add an ID tag plus their rabies tag.
• Watch for rubbing. Redness, hair loss or matting under the collar is a sign to loosen it, clean it or try a softer material.

Some little ones need time to warm up to a new collar, and our piece on whether dogs like wearing collars has tips if yours seems unsure.

Frequently asked questions

Is a martingale a good fit for a dog with tracheal collapse?

We'd skip it, since a martingale tightens around the neck when the leash pulls, and neck pressure can worsen coughing. Use a light flat collar for ID and clip the leash to a harness for walks.

Does my mostly indoor dog still need tags?

Yes, if your dog goes outside at all, even for quick potty breaks, add an ID tag plus any required rabies and license tags. Little dogs can dart out an open door faster than you'd think!
