Not recommended for dogs who pull or lunge. Our collars and leashes are designed for trained, controlled walking.

Our buckle collars are spaced out in 1-inch increments. We recommend choosing a size that coordinates with your dog's neck measurement at the middle hole. Be certain to allow for some wiggle room on either side to allow for fluctuations in weight and/or fur. We are always here to help, so please reach out with any questions you may have.

Small: 10" - 14"

Medium: 14" - 18"

Large: 17" - 22"

X-Large: 21" - 26"


Between sizes? Size up for growing puppies or thick-coated breeds.

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:

1. MEASURE YOUR DOG'S NECK

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.

2. CONSIDER YOUR DOG'S GROWTH AND FUR

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.

3. IN BETWEEN SIZES?

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

4. SIZE RANGE COLLARS (BUCKLE COLLARS)

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.

5. FIXED-SIZE COLLARS

For fixed-size collars, 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 so tight as to cause discomfort or restrict 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 that you have selected the right collar size for your dog. Do not place an order if you are unsure of the collar sizing. Please email us with any questions to info@vividcanine.com

Caring for Your BioThane® Gear:

Rinse with water and mild soap and dry with a soft cloth. Stubborn stains? Gently scrub with a soft brush.

Hardware Finishes:

Solid Brass: Develops a natural patina over time. Clean with mild soap and water regularly to minimize tarnishing.

Nickel Plated & Matte Black: Clean with mild soap and water. May show wear with use (This is normal and does not affect the integrity of the hardware).

Important Note: Please make sure to always thoroughly dry all hardware after use in any water, especially salt water. This will help to prevent the hardware from rusting.

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 most common pet and outdoor odors

BioThane® Collars FAQ

Which hardware finish should I choose?

Solid Brass stays looking like new with regular cleaning. Silver (Nickel-Plated) and Matte Black (Zinc Alloy) buckles are plated finishes that stay sharp with minimal upkeep. Nickel-Plated and Matte Black buckles are lighter weight. Heavy use on plated finishes may affect appearance over time, but won't impact performance. Rinse and dry all hardware thoroughly after any exposure to water.

Are BioThane collars waterproof?

Yes, 100% waterproof. Won't absorb water, perfect for water adventures. Just rinse and wipe dry.


How do I find the right size?

Measure your dog's neck at the base with a flexible tape. You should be able to slip 1–2 fingers comfortably between the collar and your dog's neck. If your dog is between sizes, go larger. For buckle collars, choose a range where your measurement falls near the middle. Not sure? Email us at info@vividcanine.com before ordering.



Do I need to condition BioThane?
