What is the best collar for a dog to wear?

Now, I’ve had a few dogs in my time—from tiny ankle-biters to big ol’ couch-hogging hounds—and if there’s one thing I’ve learned, it’s that one collar definitely does not fit all.

Little fellas, like Chihuahuas or Yorkies, do best with something lightweight—maybe a nice thin band, half an inch or so. You don’t want ‘em dragging around a collar heavier than they are. On the flip side, if you’ve got a bigger dog—say, a Lab or a Shepherd—you’ll want a thicker, sturdier collar, closer to an inch or more, to handle their strength and keep things secure.

No matter the size, though, the real trick is finding one that fits just right. Not too tight, not so loose it slips off, and comfy enough for all-day wear. A good collar should sit nice and flat on their neck, fasten snug, and have a spot for ID tags—because you never know when curiosity might get the best of ‘em.

End of the day, the best collar is the one your dog barely notices—but you can always count on.

What is the safest collar for dogs? 

The safest collar should be adjustable to fit the dog’s neck with room left over, is easy to remove, and carries a dog’s identification tags securely, says Collins. Although you wouldn’t put a heavy collar on a toy breed’s neck, the collar’s weight is not as important as other factors, like ease of removal or collar thickness relative to neck size, he says.  

Do vets recommend collars? 

Anytime your pup’s out and about, a good collar is a must. Not only does it help folks ID your dog if they get loose, but it also gives you something to grab in a pinch—say, if you need to gently pull your dog away from an unexpected scuffle at the park. Think of it as your safety net. Even if your dog wears a harness for walks (which we recommend, especially one of those well-made no-pull types), a collar is still handy as a backup. Harnesses can slip or fail, and when they do, that collar could be the thing that keeps your dog safe and by your side.

Should dogs wear collars at home?  

Veterinarians agree that it is best to take collars off whenever dogs play with one another or are at home alone. “For ultimate safety, it’s best never to have a collar on a dog at home, unless you are with them the whole time,” says Collins. “The point is it can get caught on a piece of furniture, on another dog’s collar, or a dog could get its teeth on the collar, or they could get their foot through it if it’s too loose.” Since so many things can go wrong, removing the collar makes sense.  

How tightly should a collar be worn? 

A lot of folks go by the old “two-finger rule” when fitting a dog’s collar, but truth be told—it oughta be a bit looser than that. You want it to lay nice and flat, without bugging your dog or digging in, kind of like a comfy T-shirt collar. When it comes to where it should sit, aim lower on the neck—closer to the shoulders and away from that tender spot near the throat. That helps keep your pup safe if they pull or lunge. And don’t forget about collar width. Little necks do better with thinner collars, while medium or big dogs can handle a wider band. Most of the ones we tested were ¾ to 1 inch thick, which worked just fine on a medium-sized pup, but if you’ve got a smaller dog, you’ll want to go with something a bit narrower—like a half-inch—so it fits just right without weighing them down.

Ah, the age-old question—like Coke vs. Pepsi, but furrier. Collars are the classic choice for everyday wear. They’re great for holding ID tags and give you something to grab in a pinch. But for actual walking, harnesses spread out the pressure across your dog’s chest and back instead of concentrating it on their neck. That’s a big deal for dogs who like to pull (looking at you, sled-dog wannabes). A good harness can make walks safer and comfier for both of you. In other words, collars are for ID and backup, harnesses are for going places without a chiropractic bill.


Martingales get a bad rap sometimes, but when used right, they’re actually a great choice—especially for pups with slim necks like Greyhounds, Whippets, or any dog who thinks slipping out of a regular collar is an Olympic sport. They tighten gently if your dog tries to back out but don’t choke like old-school choke chains. Just make sure it’s properly fitted so it only tightens enough to prevent escape, not to strangle. Used correctly, martingale collars are safe, smart, and perfect for the Houdini hounds out there.


Absolutely! In fact, getting your puppy used to a collar early on is smart. Think of it like puppy kindergarten for gear. Start with something lightweight and soft, so they don’t even notice they’re wearing it. And don’t forget—puppies grow faster than weeds in a rainstorm, so check the fit often and be ready to size up. Early collar training makes life easier later, especially for walks, vet visits, and making sure they’re always ID’ed in case they go on an unsanctioned neighborhood adventure.


If you’re asking, it might be time! Seriously though, even the best collar doesn’t last forever. Check it every so often for fraying, worn buckles, or loose stitching. Most folks replace them once a year or so, but heavy-duty dogs or swimmers might wear theirs out faster. And if your dog has outgrown it (looking at you, still-growing pups), time to size up! A fresh collar isn’t just about looks—it’s about safety, too. After all, you wouldn’t wear the same pair of socks forever, would you?
