Collar Sizing Guide
How to Measure
for Your ZOZOLU Collar
Before selecting a size, follow these four steps with your pup to ensure a perfect, comfortable fit.
Wrap a soft, flexible tape measure around the center of your dog's neck where the collar would naturally sit.
Pull the tape snug against the fur but not too tight. Take the measurement at the thickest part of the neck.
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.
Match your total measurement against the official ZOZOLU size chart below.
| S | 8" – 12" | Toy Breeds, Puppies, Small Cats |
