How do I know what size collar to get for my dog?

The best way to know what size collar to get for your dog is to measure his neck circumference right where the collar will sit. Then, compare the measurement to the size chart for the collar you want, sizing up if your dog is between sizes. Chewy includes a size chart on all collar listings to make finding the right size easy. Most dog collars are adjustable so you can get the perfect fit—after adjusting, make sure you can fit two fingers snugly underneath.

Is it safe for a dog to wear a collar?

It is safe for a dog to wear a collar, provided it is the right size and type—and make sure it’s properly adjusted. You should be just barely able to fit two fingers underneath your dog’s collar, as a collar that’s too tight can cause discomfort or hurt your dog. A collar that’s too loose is also dangerous, as it can get caught on things and potentially impair breathing. Most regular collars are designed to be worn all the time—choose one in a comfortable, skin-friendly material—but monitor your dog closely for issues and don’t ever leave novelty or training collars on for too long.

Is it better to walk a dog with a harness or a collar?

It is usually better to walk a dog with a harness rather than a collar if your dog pulls or if he can easily slip out of a collar. Although a harness can provide better control and distribute pressure more evenly, many dogs do well on walks wearing just a regular collar. Consider your dog’s temperament, physiology, and training when choosing or ask your trainer or vet for advice on which one might be best.

Should dogs wear collars at night?

Dogs should wear collars at night during walks, but at home, some experts recommend taking your dog’s collar off when the day is done. Removing the collar can provide added comfort and allow skin to breathe, but many dogs do just fine wearing a collar all the time. Ask your vet for tailored guidance if you are unsure which is best.
