Every dog needs a collar—mainly because it’s the best place to attach their leash, ID tag, license, and rabies vaccination tag.
With so many styles to choose from, you can easily find one that matches your dog’s personality (or yours!). But collars aren’t just for looks or identification. They also serve important functions, and not every type of collar is right for every dog.
Regular Collars

Flat Collar
A flat collar is the most common type of dog collar. It comes with either a buckle or a plastic quick-release clasp, along with a ring to attach an ID tag and leash.
You can find them in all sorts of colors and designs, making it easy to choose one that fits your dog’s personality.
When fitting a flat collar, make sure it’s snug but not too tight. It should be loose enough that you can slide two fingers underneath but not so loose that your dog can slip out of it.
Martingale Collar
Also called a limited-slip collar, the martingale is designed for dogs with narrow heads, like Greyhounds, Whippets, and Salukis. It’s also a great option for dogs who tend to wiggle out of their collars or for nervous dogs who might try to back away on a walk. If your dog is anxious or prone to escaping, a martingale collar is a must-have.
This collar has a loop that tightens slightly when your dog pulls or tries to slip out. Unlike a choke chain, it won’t keep tightening to the point of choking—just enough to keep the collar secure. It’s a safe and effective option for dogs who need a little extra security.

Head Collar
A head collar works kind of like a horse halter. It has two straps—one goes around your dog’s neck, sitting high behind the ears, while the other loops around their muzzle. The leash attaches to a ring under the muzzle loop.
This type of collar is great for strong or energetic dogs that pull on the leash. Because it controls their head rather than their neck, they can’t use their full body weight to pull.
Getting your dog used to a head collar takes time and patience. Start by letting them wear it for short periods while rewarding them with treats. Once they’re comfortable, use it only when you’re walking them on a leash. Never leave it on all the time—eventually, they’ll figure out how to get it off and turn it into a chew toy!

Aversive Collars
Aversive collars are designed to stop bad behavior by causing discomfort or pain—but they’re not a humane or effective way to train a dog.

While they might make a dog stop a behavior temporarily, they don’t teach what the right behavior is. Worse, they can create fear and anxiety, which can lead to aggression.
Positive reinforcement—using rewards like treats and praise—is a much better way to train your dog and build a stronger bond.
Choke Chains
As the name suggests, choke chains are metal collars that tighten around a dog’s neck when they pull. Unlike martingale collars, there’s no limit to how tight they can get, which means they can choke or even strangle a dog.
These collars can cause serious injuries, including trachea damage, neck sprains, nerve damage, and even death. They’re also very easy to misuse, making them a dangerous choice. With so many humane and effective collars available, there’s no good reason to use a choke chain.
Prong (Pinch) Collars
Prong collars work similarly to martingales, but instead of fabric, they have metal links with blunted prongs that press into a dog’s neck when the leash is pulled.
The idea is to mimic how a mother dog corrects her puppies, but in reality, these collars can easily be misused and cause unnecessary pain. Like choke chains, they’re not a safe or humane way to train a dog.

Shock Collars
Shock collars work by sending an electric signal through metal contact points on the collar. This can range from a mild tingle to a painful shock.
They’re often sold as training tools or used with invisible fences, but they’re controversial and increasingly being removed from stores. Shock collars can cause fear, anxiety, and even aggression toward people or other animals.
While they might stop unwanted behavior in the moment, they don’t teach the dog what to do instead. That’s why they’re not a good training method.
Electronic Fences
Electronic fences use shock collars to create an invisible boundary. When the dog gets too close to the edge, they first hear a warning tone—then, if they keep going, they get a shock.
The problem? If a dog is excited or scared enough to run through the fence, they’ll get shocked again when trying to come back. This can make them afraid to return home, leading to lost or stray dogs.
The Better Alternative
If you want to train your dog effectively, skip aversive collars and go for positive reinforcement methods instead. Rewarding good behavior works better, keeps your dog happy, and strengthens your relationship.

Special Use Collars

There are many types of collars designed for different purposes, but not all of them are effective or necessary. Let’s break them down in simple terms.
Bark Control Collars
These collars are meant to stop excessive barking, but they don’t fix the real reason your dog is barking. Dogs bark for many reasons—fear, boredom, excitement, or protecting their territory.
While bark collars might make them bark less, they don’t take away the stress or emotions causing the barking in the first place.
- Spray Collars: These release a puff of citronella or air when your dog barks to startle them into stopping. However, they don’t always work on high-pitched barks. Also, if your dog is around other barking dogs, their collar might get triggered even when they’re not barking.
- Ultrasonic Collars: These give off a high-pitched sound only dogs can hear when they bark. Some dogs respond to it, but others don’t.
Flea & Tick Collars
These collars are treated with chemicals that help keep fleas and ticks away. They’re worn along with a regular collar and need to be replaced as recommended to stay effective.
Vibrating Collars
Instead of using a shock, these collars vibrate to get your dog’s attention. They can be helpful for training, especially for deaf dogs who can’t hear voice commands or clickers.
Elizabethan Collars (E-Collars)
These are the wide, plastic cone-shaped collars vets give dogs after surgery or injuries. They stop dogs from licking or scratching wounds so they can heal properly.
Most attach to a regular collar, and some have Velcro closures. Your dog should still be able to eat and drink while wearing one, but if they really hate it, there are softer, more comfortable options available.

GPS Collars
These collars have GPS tracking to help you find your dog if they ever get lost. While they’re great for keeping track of pets, they rely on satellites and battery life, so they may not work well in remote areas.
Each collar serves a different purpose, but the best choice always depends on your dog’s needs. Want help picking the right collar for your pup?
