What Pro Collar is made of
The dog that deserves a collar built to match.
For owners who already have the Eclipse or a PRO harness and want a collar to match — same construction, same hardware spec, same guarantee. For giant breeds whose strength demands steel at the D-ring. For dogs whose current collar has worn through, frayed, or failed.
The DUO Guarantee
Lifetime guarantee on materials and workmanship. If it fails for any reason — we fix or replace it. No time limit, no fine print.
"Everything DUO makes starts from the same question — what would actually solve this? The Pro Collar exists because most collars aren't built to the same standard as the harness they sit next to."
