Does my dog need a collar? New pup parents ask the question a lot, and the answer is simple: yes! Every dog should have a collar. Not only are they necessary to attach leashes, licenses, IDs, and vaccination tags, but they can also be helpful when training.
However, not all dog collars are created equal — and some are downright inhumane. Moreover, different types of collars are suited for various purposes, dog sizes, and life stages.
So which collar is best for your pup? We tested tons and came up with a list of superlatives. Our pet product review team considered several factors during the trial process, including price, ease of use, effectiveness, style, and durability.
Dog Collar Materials
Collars come in a variety of materials, each with drawbacks and benefits.
Dog Collar Materials: Neoprene
Best known as “wetsuit material,” neoprene is a soft rubber material reinforced with nylon. It’s strong, highly durable, and stretches well. Water-loving dog breeds — like American water spaniels, barbets, Irish water spaniels, Portuguese water dogs, Newfoundlands, and Labrador retrievers — do best with neoprene dog collars. They’re also great for puppies and dogs with skin allergies.
Unfortunately, not many companies make neoprene dog collars, so the selection is limited. Plus, they can be a bit bulkier than pure nylon options and a little less budget-friendly.
Dog Collar Materials: Nylon
Nylon collars are the most common and come in a wealth of styles and colors. The material is great for everyday wear — both outside and around the house.
Dogs with skin irritation issues may have problems with nylon collars. In such cases, a neoprene one may work better. Also, they may stink to high heaven after a while and are difficult to clean. But they’re usually on the less expensive side, so replacing them isn’t a huge investment.
Dog Collar Materials: Biothane
Biothane is another collar material that’s good for water-friendly canines. The non-toxic substance is made by coating a polyester base with either polyvinyl or polyurethane. A great alternative to other options, biothane is flexible, softer than many other dog collar materials, and less expensive!
Moreover, biothane is tough as snot and lasts a long time, making it a good choice for rough and aggressive dogs who chew on their collars. Budget-wise they’re a good choice since you won’t have to buy as many as often.
The only downside to biothane collars is that they can be difficult to find.
Dog Collar Materials: Leather
Leather is the Bentley of collar materials: it’s high-quality, lasts for years, and looks good! But leather is also the most expensive option. However, for people with a budget, they’re durable, classy, and easy to wipe. Moreover, since they’re made of a natural material, they’re better for dogs with certain skin allergies.
Leather collars come in two types: flat and rolled. Use the latter for canines with thick hair that mats easily. If durability is a concern, make sure the collar is long-grain leather and not bonded leather. The latter disintegrates at a much quicker rate than the former.
Like nylon, leather can start to reek after a while — which may be a consideration for people with sensitive olfactory systems.
Dog Collar Materials: Chain
Chain collars should only be used by professionals in controlled environments. Moreover, they should never be left on an unattended canine because the risk of self-strangulation is high, especially in colder months when the metal is less pliable.
Chain collars are not an everyday option. Not only are they impractical since they don’t work properly with most leashes, but they’re also dangerous in most circumstances.

Do you want to personalize a dog collar? Look no further than ZTZ’s personalized dog collars. They run about $25 but are strong and last a long time. Instead of using overlays that quickly wear off, ZTZ’s collars have laser engraved buckles.
Fashion is the word that immediately came to mind when we first saw these collars for people who like to personalize. They come in a variety of prints, and the shiny, silver buckle makes them a tasteful standout. They’re the kind of collars that will garner compliments from strangers.
Keep in mind that the buckle is quick-release, which means it may snap off if your dog fights or gets tangled in something. We see this as a welcome safety measure, but it may not be for rambunctious pups. That said, our team member with a feisty puppy said ZTZ’s collar worked great and didn’t snap off.
To personalize, you have the choice of inscribing a name, address, and telephone number. We suggest, however, you only use the name and number sections because revealing your address isn’t the safest move.
The ZTZ Custom Laser Engraved Collar comes in five sizes — from XS to XL.

Best Martingale Dog Collar: Country Brook Petz Martingale Heavy Duty Nylon Dog Collar
- 1 INCH WIDTH | Adjustable from 15 inch - 21 inch neck. Be sure to use our martingale sizing chart for the most accurate fit. (Use the true “snug” measurements)
- NO BUCKLE | Perfect for training, Martingale-style collars give you gentle control over your pet. Designed to be escape proof, this collar slips over the head and tightens when pulled. Traditional Martingale style collars do not feature a buckle.
- Personalize your pup with rich, fashionable colors and mirror like metal hardware. The classic style of this collar looks cute on both boy and girl dogs. Our unique collars will give your pup character.
- Silky soft nylon webbing means your dog will stay comfy. Adjustable so you can have the perfect fit. Worn like a hug.
- Made in the U.S.A. with nickel plated steel hardware for superior strength; won't break or fray as easily as plastic collars. Not for tie out.
The Country Brook Petz Heavy Duty Martingale Collar is the best rated in Amazon. But that’s not why it’s our number one pick. That’s just an added bonus and what initially caught our attention. We considered this the best overall martingale collar because it checks all of our requirements – durability, comfort, style, size, and cost.
This martingale collar is made of high tensile strength nylon with box stitching located at pressure points to increase durability. This heavy-duty material is soft and comfortable; it isn’t going to snap easily even if your pup is a strong puller. More importantly, nylon is able to handle moisture and humidity well. Getting it wet, either by cleaning it or because of your dog’s antics, isn’t going to affect its sturdiness.
This best-rated collar also features welded nickel-plated steel rings which won’t break or corrode. There’s no risk of the metal rubbing against your fur baby’s neck and causing discomfort or, worse, chafing and/or sores. Whether your dog’s hairy, hairless, or hypoallergenic, they’re not going to notice this collar until you’re pulling the leash.
Aside from being well-made and sturdy, we loved the fact that Country Brook offers a wide selection for dog owners. From sizes that fit Chihuahuas to German Shepherds and colors ranging from mango to royal blue, you won’t have a hard time finding a martingale collar that suits your energetic doggo. Plus, it doesn’t hurt that the collar only costs around $10. Your wallet won’t feel the pinch.
Obviously, there are numerous benefits to getting this heavy-duty martingale collar from Country Brook. Based on our doggos’ experience, your pets shouldn’t have any problems wearing it. In fact, out of all that we tested, this collar performed best whether dry or wet. But we did find a few customers who weren’t so happy. A few mentioned that the color leached onto their pup’s furs which can be an issue unless you wanted a hot pink dog (or something similar). And if you have an enthusiastic dog on your hands, you might find it difficult to slip on the collar and adjust the fit properly.

Best Overall Flea Collar: Seresto Flea and Tick Collar for Dogs
- Provides 8-months of continuous flea and tick prevention
- Seresto flea and tick collar for large dogs works through contact, so fleas and ticks do not have to bite your dog to die
- Veterinarian-recommended flea and tick prevention for dogs in a convenient, odorless and non-greasy collar; No need for messy monthly treatments
- Starts to repel and kill fleas within 24 hours of initial application
- Flea and tick collar for large dogs also helps treat and control sarcoptic mange and kills lice
When it comes to the prevention and treatment of fleas and ticks, the flea collar that is recommended by most vets is Seresto. Its two main ingredients are imidacloprid and flumethrin which, as this study shows, is incredibly effective in taking out fleas and ticks. Of course, we couldn’t just take their word for it. We had to do some testing on our own.
Based on our experience, this flea collar had no odor at all which makes it ideal for sensitive noses (and we’re not just talking about dogs here). Plus, it comes with a non-greasy formula. More importantly, our happy volunteer (one of the doggos of our staff) didn’t catch any fleas or ticks after we left him romping around outdoors.
Of course, flea prevention is not the only thing this collar is good for. According to Bayer, it should be able to kill fleas – both adults and eggs – within 24-48 hours after application. Using a different dog, we did find that it does reduce the number of fleas we could find on his fur within their promised time frame. And none of our volunteers had allergic reactions to the collar while wearing it for several days. So, fast-acting and effective? Check!
Some other things that you need to know about the Seresto collar. It features reflector chips for visibility at night. It comes with a quick safety release mechanism in case the collar gets caught on something. Plus, the collar can also treat sarcoptic mange.
As much as we loved this product, we do have to be honest about some of the drawbacks of using the Seresto collar. First is the cost. Compared to other collars in the market, this one is priced at over $50. It definitely does not come cheap (though well worth the price). The second disadvantage is that this flea collar is only water-resistant, not waterproof. Unless you only let your dog bathe or get wet once a month, the effectiveness of this collar against fleas goes down from 8 months to 5.
Overall, the Seresto collar receives a huge thumbs up from us. Just keep in mind that Bayer offers two types of Seresto collars. One is for large dogs weighing 18 lbs and over. The other is for small dogs weighing less than 18 lbs. Make sure to read the label before buying.

The 8 Best Dog Collars: Reviewed for 2021 FAQs (Frequently Asked Questions)
What Is the Best Type of Collar for a Dog?
It depends. Collar choice depends on several factors, including size, breed, skin sensitivity, and water exposure. Scroll up to see our picks for best dog collars in multiple categories.
What Are the Safest Dog Collars?
Generally speaking, breakaway collars are the safest. They prevent strangulation in the event your pup gets caught in either shrubbery or the jaw of another animal.
Should Dogs Wear Collars 24/7?
Dogs should wear collars every time they leave the house. Not only are collars needed for a leash, but they’re also ID facilitators. And pets with ID tags are much more likely to find their way back to their humans.
However, if your pet is safely inside and there’s no chance of escaping, it’s fine to remove collars and let the area’s skin breathe.
What Are the Best Dog Training Collars?
Our pick for the best training collar is PetSafe's nest training dog collar, a simple option for everyday training.
Who Makes the Best Leather Collars?
Coach, Gucci, and Burberry — the venerated luxury brands — all make haute couture leather dog collars. But they’re costly. Our pick for the category is Moonpet’s padded full-grain leather collar.
Are Prong Collars Safe?
Prong collars are outfitted with fang-shaped links — called “prongs” — that cut into dogs’ necks when pulled. They’re similar to choke chains, they’re inhumane, and they should not be used. No, prong collars aren’t safe.
Are Shock Collars Safe?
This is a tricky question. On the one hand, the vibration administered by shock collars is, technically, safe and has not been shown to cause damage. Used liberally among hunters, they do work well when training pups for the hunt.
However, there’s an argument to be made that shock collars are inherently inhumane because they can cause fear, anxiety, and aggression in some dogs.
Moreover, some malfunctioning shock collars have caused electric burns.
Generally speaking, shock collars are an extreme tool that should only be used sparingly by trained professionals in highly controlled environments.
Should I Harness My Dog?
To harness or not to harness? It’s a question that a lot of dog owners have been asking as of late. Unfortunately, the answer isn’t simple. Whether or not to use one, in large part, depends on the dog. Some love them because they loathe things around their neck. Others find harnesses too cumbersome.
Ultimately, the only way to determine if your pup should use a harness is to get one and see if they take to it.
How Do I Choose the Right Size for My Dog?
Sizing is essential when choosing a collar. To get an accurate measure of your hound’s neck:
- Use a flexible measuring ribbon. If you don’t have one, use a shoelace or piece of string.
- Wrap it around your pet’s neck and mark where the two ends meet.
- Get a ruler, stretch the string parallel to it, and note the measurement that corresponds with the mark.
How Do Collars Work?
Collars work in a variety of ways. Basic ones simply attach around the animal’s neck. These types usually contain D-rings, onto which leashes are attached and identification is hung. On the other hand, technologically enhanced training collars may emit pulses, light signals, and vibrations.
