RexDuchess silver whistle

Rex by House of Mutt


Solid silver whistle necklace made in Birmingham by the world renowned Acme Whistle Company.  Solid silver rings and faceted charm bead threaded onto a comfortable and secure, soft, nappa leather thong.  Hallmarked in Birmingham with the unique Rex hallmark.

Available in both 210.5 and 211.5 pitches.

If you’re not of aficionado status and want guidance, we recommend going for the 211.5 (‘two eleven and a half’) pitch, as opposed to the 210.5 (‘two ten and a half’) which is most commonly used in Field Trialling competitions.


Made by hand in Birmingham’s Jewellery Quarter by the Acme Whistle Company, who have been making whistles at this same site since 1881.

A few facts about Acme:

  • They invented the original Metropolitan Police whistle in the 1880s
  • They have sold enough Thunderer Sports whistles to fill 12 Jumbo Jets
  • Their largest ever single order was for 7 million whistles in the 1980s
  • We'd love them to make 7 million Duke and Duchess whistles for Rex!
  • They first made a solid silver whistle as a gift for Her Majesty The Queen and have adapted that original mould for us

The collaboration between Acme, the provider of the world’s best dog whistles, and Rex by House of Mutt, the provider of the world’s best dog kit (we believe!),  is an exciting development for both parties.
