Dog Collars, Leashes & Harnesses

Dog collars are an essential accessory for every canine, and collars for dogs come in a variety of styles, materials, types, and sizes. A dog collar makes it easy to snap on a leash anytime for a walk or potty break. The collar can also provide necessary safety and/or contact information if your dog gets lost—hang your dog’s ID tags from the collar’s tag ring or get a personalized style printed with your dog’s name and your phone number.

Choose from a range of dog collar types to suit your needs:
• Standard dog collars: Classic style and function
• Fashion dog collars: Show off your pup’s unique personality
• Personalized dog collars: Include your pet’s name or contact info for safety
• Martingale collars or headcollars: Recommended for training use
• Chain or prong collars: Another collar option for training
• Electronic collars: Used for remote training, or with electronic fences

Select a collar in a material that suits your dog’s lifestyle and needs. You can find dog collars in nylon, fabric, rope, leather, silicone, vinyl, neoprene, reflective materials, and more in fun colours, prints, and styles. There are even lighted collars for added visibility on nighttime walks. Most dog collars are adjustable, and they come in various widths and sizes to accommodate a variety of breeds. Pick one that suits your dog’s personality and provides style, safety, and functionality on every outing!

FAQ 1: 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.

FAQ 2: 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.

FAQ 3: 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.

FAQ 4: Are thicker or thinner collars better for dogs?
Thicker collars are sometimes better, as they distribute pressure more evenly for comfort and safety—this is especially important for larger and more powerful dogs. However, a thicker and/or wider collar may be too cumbersome or heavy for smaller dogs, so consider weight and your dog’s frame size when choosing.

FAQ 5: 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.
