Quick Summary
The best material for a dog collar is full-grain vegetable-tanned leather, it is the most durable, most comfortable, most skin-safe, and most environmentally considered option available for everyday wear. Collar choice then depends on three further factors: the right size for your dog’s neck measurement, the right width for their breed anatomy, and the right style for their activity level and daily routine. This guide covers all three, with The Lille Björn’s confirmed size chart and breed-specific recommendations throughout.
Your dog’s collar is more than just an accessory. It’s also something that plays a role in safety, comfort, and their overall wellbeing. When you think about the best dog collars, think about your pet’s personality, size, breed, and activity level. Size, style and material are some of the biggest considerations when choosing accessories, including collars, dog leashes and dog harnesses. This guide will help you make the right decision for your beloved animal.
The Importance of Choosing the Right Collar
Your dog’s collar has many uses. It’s a place to attach identification tags and their dog leash. It’s also something that reflects yours and your dog’s personality. Choosing the wrong collar will leave your pet uncomfortable and can even be dangerous. That’s why it’s important to take the time to find the ideal collar type and accompanying accessories for your best friend. Let’s find out more.
The Best Material for a Dog Collar
Why Material Comes First
Material determines everything that follows: how the collar feels against your dog’s neck for 16+ hours per day, whether it irritates or soothes sensitive skin, how long it lasts before degrading, and how it behaves when wet, dirty, or repeatedly stressed.
Nylon
Nylon is inexpensive and lightweight. It’s also quite durable and comes in a variety of colors and patterns. It’s a good choice for short-haired dogs, but may cause tangles and matting in dogs with longer hair.
Neoprene
If your dog loves swimming and getting wet, or is generally very active, neoprene makes a good choice. The material is durable and water resistant and can handle a high activity lifestyle.
Metal Chains
Metal chain collars are for training contexts only under professional guidance. They are not appropriate for everyday or all-day wear: they concentrate pressure on a very small area of the neck, have no maximum tightening limit, and can cause pain, bruising, and tracheal damage under sustained or repeated tension.
Vegetable-Tanned Leather — The Best Choice
Full-grain vegetable-tanned leather is the best material for dog collars for four specific reasons:
- Hypoallergenic and skin-safe: processed using only plant-based tannins with no chromium salts, synthetic dyes, or chemical preservatives. It is the safest material for daily neck contact, particularly for dogs with sensitive skin or existing skin conditions.
- Naturally antibacterial: the natural tannins in the leather create a surface that resists bacteria and odour, a meaningful hygiene advantage for a collar worn every day.
- Softens and conforms: vegetable-tanned leather starts firm and softens over weeks of daily wear, moulding to the exact shape of your dog’s neck to produce the most custom fit any collar material can provide.
- Lasts 5–8 years: a quality leather collar outlasts nylon and synthetic alternatives by years, making it more cost-effective over the dog’s lifetime despite a higher upfront price.

Selecting the Right Size
If your dog’s collar is too tight, it can restrict breathing and be quite uncomfortable. Over time, this can lead to health issues that you certainly don’t want your dog having to live with. On the other hand, a collar that is too loose allows your pet to slip out, which can be dangerous if you’re on a walk and there are cars and other dogs around.
How to Measure Your Dog’s Neck
It’s important to determine the right size when buying a dog collar. Keep in mind that if your dog isn’t done growing, you will have to buy a new collar several times as they get bigger. Monitor your dog’s collar closely so you know when it’s time to move up to a new size. Use these steps to get the job done right:
- Use a flexible measuring tape at the base of your dog’s neck. Measure snugly around the middle of your dog’s neck where the collar will naturally rest. Be sure the tape is snug against the neck but not too tight, and don’t leave extra space. The collar should fit comfortably without pinching.
- Our collars are true to size, so it’s important to measure correctly to ensure a proper fit. Each collar size reflects its inner circumference range. For example Size S (27-32 cm) аits necks measured between 27-32 cm. If your dog’s neck measurement falls within a specific range, choose the collar size that corresponds to that range.
- Check for breed recommendations because some dogs have special sizing needs, such as bulldogs with their thick necks or Greyhounds, who generally have very thin necks.
For the complete protocol see our dog collar measuring guide.
The Lille Björn Size Chart
Understanding the common sizes for various sized dogs gives you a good place to start. Consider the following general recommendations, then use that as a guide to help you find the best fit for your beloved pet.
| Size | Neck Circumference | Typical Breeds |
|---|---|---|
| XXS | 17–22 cm | Chihuahua, Toy Poodle, Pomeranian |
| XS | 22–27 cm | Yorkshire Terrier, Miniature Dachshund, Maltese |
| S | 27–32 cm | Shih Tzu, Cocker Spaniel, Whippet, Standard Dachshund |
| M | 32–37 cm | Border Collie, Beagle, French Bulldog, Greyhound (small) |
| L | 37–42 cm | Labrador, Golden Retriever, German Shepherd, Greyhound (large) |
| XL | 42–47 cm | Great Dane, Mastiff, Saint Bernard, Rottweiler |
The two-finger check: once the collar is buckled, slide two flat fingers between the collar and your dog’s neck. Two fingers with light resistance = correct fit. Cannot fit two fingers = too tight. Two fingers slide through easily and the collar rotates freely = too loose.
Check the fit monthly for adult dogs and fortnightly for puppies, growth and seasonal coat changes both affect fit.
Choosing the Right Style
Design is definitely a great way to showcase your dog’s personality (and your own), but you should also take function and comfort into consideration when making your choice.
Collar Width
Width determines how pressure is distributed across the neck and which breeds are best served by each option.
Classic width (2.5–3 cm) suits most breeds: medium dogs, small breeds, and any dog without specific anatomical requirements. Lightweight enough for all-day wear without bulk.
Wide width (4–4.5 cm) suits large breeds, giant breeds, and sighthounds. A wider band distributes leash pressure across a larger surface area, reducing the force per square centimetre at any point on the neck. For Greyhounds and sighthounds specifically, a wide collar also provides meaningful escape resistance: the structural stiffness of a wider band resists the folding that allows a narrow collar to slip over a narrow head. For more guidance, see our complete guide to choosing the right collar width.
Rolled collar suits long-coated and silky-coated breeds (Setters, Spaniels, Afghan Hounds, Borzois). The cylindrical profile glides through the coat rather than pressing it flat, preventing the matting that a flat collar causes at the contact zone over months of continuous wear.
Collar Type
- Flat collar: the best everyday collar for most dogs, comfortable, versatile, and appropriate for all-day ID wear. Correct for most breeds and lifestyles.
- Wide flat collar: the correct choice for sighthounds (Greyhounds, Whippets, Salukis) and large breeds where pressure distribution matters. For sighthounds specifically, a martingale collar from a sighthound specialist can be used alongside the wide flat collar for walks where maximum escape security is needed, the flat collar carries the ID, the martingale handles walk security.
- Rolled collar: for long-haired and silky-coated breeds where coat care is a consideration. Prevents matting at the contact zone.
- Breakaway collar: a useful option for dogs that frequently move through dense undergrowth or tight fencing, where a standard buckle collar could catch and trap them.
Matching Collar to Breed
Different dog breeds have different needs when it comes to choosing the best collar. That includes their size, hair length, hair type, and activity level. Let’s find out more about this.
Small Breeds
Chihuahuas, Yorkshire Terriers, Maltese, Shih Tzus, and Toy Poodles suit a narrow lightweight collar in XXS (17–22 cm) or XS (22–27 cm). The collar’s weight should be proportionate to the dog’s frame, a heavy wide collar on a small breed is disproportionate and uncomfortable. For Chihuahuas and other toy breeds, a back-clip harness for leash attachment alongside a slim flat collar for ID is the most protective everyday setup, keeping all leash tension off delicate necks.
Medium Breeds
Beagles, Cocker Spaniels, Border Collies, Australian Shepherds, and French Bulldogs typically fall in size S (27–32 cm) or M (32–37 cm). A 3 cm classic width collar suits most medium breeds well. Border Collies typically measure 34–40 cm, suiting size M. French Bulldogs consistently have thicker necks than their body size suggests, always measure before ordering and err toward size M or L.
Large Breeds
Labradors, Golden Retrievers, German Shepherds, and Huskies typically suit size L (37–42 cm). A 3–4 cm width provides the right balance of pressure distribution and proportionality. Golden Retrievers measure 37–44 cm on average and suit size L well. For large breeds that pull consistently, a back-clip harness for walk use alongside the collar for ID is the most protective setup.
Giant Breeds
Great Danes, Mastiffs, Saint Bernards, and Newfoundlands suit size XL (42–47 cm) or above. A wide collar of 4–4.5 cm is appropriate for the neck proportions of these breeds. For measurements above 47 cm, contact The Lille Björn directly for custom sizing options.
Sighthound Breeds
Greyhounds, Whippets, Salukis, Italian Greyhounds, and Pharaoh Hounds require a wide flat leather collar specifically as their lean, fat-free necks cannot absorb concentrated collar pressure, and their narrow heads create a genuine escape risk from standard-width collars. See our complete sighthound collar guide for full sizing and recommendations.
The Case for Vegetable-Tanned Leather in Detail
What Is Vegetable-Tanned Leather?
Vegetable tanning is done using natural tannins, found in tree bark and other plant matter. These tannins take the place of chemicals that are used in other tanning techniques. The result is an eco-friendly process that lends sustainability and character to your dog’s collar.
Best Uses for Genuine Leather Dog Collars
Leather is comfortable and breathable enough for daily all-day wear. It holds up well to normal outdoor conditions. If the collar gets wet, allow it to air dry away from direct heat and sunlight. Condition with a leather conditioner every two to three months to maintain suppleness. Leather is particularly well-suited to large, active dogs and to dogs with sensitive skin, the two groups where material choice is most consequential for daily welfare.
Collar Maintenance
When you choose a leather dog collar, you choose a durable and long lasting option that will age with your pet. However, to keep it in top shape, you should practice proper care and maintenance on a regular basis. Follow these steps for the best results:
Taking care of your leather dog collar is simple and helps keep it looking great and lasting longer. Here are a few easy tips to maintain its quality and durability:
- Clean it regularly: Use a damp cloth to gently wipe away dirt and debris. If needed, you can use a small amount of mild detergent diluted in water to clean the collar, but avoid soaking it or scrubbing too hard. Harsh cleaners should be avoided, as they can damage the leather. A quick wipe-down every so often is usually all it needs to stay fresh.
- Condition the leather: Leather can dry out over time, so applying a leather conditioner once a month (or as needed) helps keep it soft and prevents cracking. This will ensure the collar stays comfortable for your pet and keeps its beautiful appearance.
-
Keep it dry: While a little water won’t harm leather, too much can weaken it. If your dog loves swimming or playing in the rain, it’s a good idea to remove the collar first. For extra protection, you can use a water-resistant coating. If the collar does get wet, let it air dry naturally—don’t use direct heat or sunlight.
-
Check the hardware: inspect the buckle, D-ring, and snap hook regularly. Solid brass hardware is an excellent choice because it doesn’t rust, while stainless steel is highly resistant to rust but might develop small spots over time with frequent water exposure. Regularly inspect the hardware and attachment points to ensure everything is secure and safe for your dog.
With a little care and attention, your dog’s leather collar will stay in great condition for years. A clean, conditioned, and well-maintained collar not only looks good but also keeps your furry friend safe and comfortable.
Frequently Asked Questions: Choosing the Right Dog Collar
What is the best material for a dog collar?
Full-grain vegetable-tanned leather is the best material for dog collars. It is hypoallergenic, naturally antibacterial, softens to a custom fit over time, lasts 5–8 years under daily use, and is made without the chromium salts and synthetic chemicals that can cause skin reactions in sensitive dogs. It is also biodegradable, the most environmentally considered collar material available. For dogs with very water-intensive lifestyles (frequent swimmers), neoprene is a functional alternative.
How do I measure my dog for a collar?
Wrap a soft tape measure snugly around the middle of your dog’s neck, where the collar will naturally sit. That measurement in centimetres is your collar size on The Lille Björn chart. Confirm the fit after ordering with the two-finger check: two flat fingers with light resistance between the collar and the neck is the correct fit.
What size collar does a Border Collie need?
Most Border Collies measure 34–40 cm at the middle of the neck and suit size M (32–37 cm) or L (37–42 cm). Measure individually before ordering as Border Collies vary considerably in build. A 3 cm classic width collar suits the Border Collie’s active, medium-necked profile well.
What collar is best for a Greyhound?
A wide flat leather collar of at least 4 cm in width the Vero Wide or Aeris Wide. Greyhounds have lean, fat-free necks and heads narrower than their necks, making a standard-width collar both a pressure risk and an escape risk. A wide flat collar distributes pressure safely and provides meaningful escape resistance. Most Greyhounds suit size M (32–37 cm) or L (37–42 cm).
What is the best collar material for dogs with sensitive skin?
Full-grain vegetable-tanned leather as it contains no chromium salts, synthetic dyes, or chemical preservatives, which are the primary contact allergens associated with collar-related skin reactions. Its naturally antibacterial surface also resists the moisture and bacteria buildup that worsens existing skin conditions. Dogs that have reacted to nylon or chrome-tanned leather collars typically tolerate vegetable-tanned leather without issue.
Should I choose a wide or narrow collar for my dog?
A 3 cm classic width suits most medium breeds well. A wide collar (4–4.5 cm) is the correct choice for sighthounds, large breeds, and giant breeds, the wider band distributes leash pressure more evenly across the neck surface. A rolled collar is the right choice for long-coated and silky-coated breeds where flat collar contact would cause coat matting over time. See our complete guide to choosing the right collar width for your breed.
When should a dog wear a harness instead of a collar?
A back-clip harness should handle leash attachment whenever: the dog pulls consistently; the breed is brachycephalic (Bulldog, Pug, French Bulldog); the dog has tracheal sensitivity; or the dog is a small or toy breed where any neck pressure is a welfare concern. In all these cases, the collar is retained for ID tag attachment while the harness carries the leash. The combination of flat leather collar for ID, back-clip harness for walks is the most considered everyday setup for any dog where neck pressure is a consideration.
The Right Collar for Your Dog
The perfect collar is the one that fits correctly, is made from a material appropriate for your dog’s skin and lifestyle, and is sized and styled to suit their breed anatomy. For most dogs, that means a full-grain vegetable-tanned leather collar in the right size from The Lille Björn’s XXS–XL range available in Classic and Wide profiles, five colours, and with optional name engraving for permanent, silent identification.
