For powerful dogs (38–47 cm) like the Border Collie, Australian Shepherd, and dogs with a sturdy neck. This wide 4 cm band is a real statement and distributes pressure optimally.

Prevent returns: Many owners order unnecessarily large. Measure the neck tightly. At 46 or 47 cm, L is perfect; XL is really too big. Choose this 4 cm version for a robust, bold look.
