Collar Sizing Guide


POSITION

Wrap a soft, flexible tape measure around the center of your dog's neck where the collar would naturally sit.

WRAP & MEASURE

Pull the tape snug against the fur but not too tight. Take the measurement at the thickest part of the neck.

ADD THE TWO-FINGER RULE

Slide two fingers flat between the tape and your dog's neck. This ensures optimal breathing room. Because premium BioThane is structured and will not stretch, an accurate neck measurement ensures the best fit.

SELECT YOUR SIZE

Match your total measurement against the official ZOZOLU size chart below.



S 8" – 12" Toy Breeds, Puppies, Small Cats

ZOZOLU TIP
If your dog's neck measurement falls directly between two sizes, always size up to ensure maximum comfort and prevent any chafing.
