To choose the best collar size for your dog, we always recommend measuring your dog's actual neck size (where your dog's collar naturally sits). We do not recommend using your dog's current collar to obtain a neck measurement, as hardware, collar material, and thickness vary by each collar. If you are unsure about what collar size to choose, send us a message to and we'd be happy to help! If you would like a size that is not currently in the options, send us a message or leave a note at checkout and we'll be happy to accommodate you!

Fixed sizes 8" - 16" are available in widths 5/8", 3/4", and 1". Additional sizes in 1/2" increments up to 24.5" are available. For additional sizes above 16" 3/4" width, select any size and place a note in the order section with your size request. If you have questions, please contact us at

Tips for Measuring

When it comes to finding the perfect collar for your dog, getting the right size is essential. A collar that is too tight can be uncomfortable and restrict your dog's movement, while a collar that is too loose may slip off or pose a safety risk. To ensure a proper fit, follow these guidelines:


Using a flexible measuring tape, measure the circumference of your dog's neck. Make sure to measure at the base of the neck, where the collar will sit. There should always be enough room between the pet’s neck and the collar to slip one to two fingers between them comfortably. This ensures that the collar isn't too tight. Make a note of the measurement in inches or centimeters.


If your dog is still growing, it's best to choose a larger size to accommodate their future growth. Additionally, if your dog has a lot of fur around their neck or experiences weight fluctuations throughout the year, consider these factors when selecting a size.


If your dog's neck measurement falls in between two sizes, it's recommended to choose the larger size.


For collars with a size range, it's best to choose the range where your dog's measurement is close to the middle. This allows for adjustments both up and down, providing a better fit.


For collars with a fixed size, it is very important to obtain an accurate measurement of your dog's neck where the collar is normally worn, as these collars are NOT adjustable. Take into consideration the thickness of the dog's fur to be certain you are getting an accurate measurement of the dog's neck.

Remember, a properly fitting collar should be snug enough to stay in place, but not too tight that it causes discomfort or restricts your dog's movement. By following these guidelines, you can ensure that your dog's collar fits comfortably and securely.

We want you to be confident you have selected the best size collar for your dog. Do not place an order if you are unsure of the collar sizing. Please email us with any questions to



Hand-wash with mild soap and water. Dry with a soft cloth to maintain the longevity of your new leash.

Please note: We use solid brass hardware on all of our leashes and collars. Make sure to rinse and dry all hardware thoroughly after swimming or washing. Solid brass hardware can patina over time, to help keep your hardware looking new, we recommend occasionally polishing your hardware. Regular cleaning is recommended to keep your BioThane gear looking new.

Why Biothane?

BioThane is made with a Polymer coated webbing. The Polymer coating makes this webbing a great leather alternative, as it is more durable, waterproof, and easy to clean. It is maintenance-free, rinses clean in seconds, will not mold or mildew, and will not absorb odors.
