FAQ: Fi Dog Collars

What Fi models are supported?

These collars are compatible with Fi Series 3 and Fi Series 3+ devices.

What is the difference between Rugged, Sport, Classic, and Luxe?

  • Rugged -> waterproof canvas and maximum durability for active dogs.
  • Sport -> waterproof BioThane with lightweight everyday flexibility.
  • Classic -> patterned cotton fabrics for polished everyday style.
  • Luxe -> soft velvet with a refined look and feel.

Each collection is built around the same Fi-compatible setup.

Are your collars waterproof?

Rugged and Sport collars are waterproof. Classic and Luxe collars are best for everyday wear and should be dried thoroughly if they get wet.

What is the Dog Head Lock system?

It is a screw-lock system that lets you fine-tune the fit within each size range, creating a secure collar that will not slip or shift.

Where are your collars made?

All HUND HAUS collars are handmade in Denver, Colorado.
