A Blue Merle Yorkshire Terrier is a Yorkie carrying the merle gene — producing a mottled, marbled coat pattern with dilute blue/grey patches, often paired with one or two blue eyes. The look is striking and rare. The genetics need a careful breeder.

The merle gene, in plain English

Merle is a single dominant gene that lightens random patches of a dog's coat (and sometimes their eyes). One copy of the gene produces a beautiful blue-merle look. Two copies — called "double merle" — produces serious health issues: deafness, blindness, and immune problems.

That means an ethical Blue Merle breeding pairs one merle parent with one non-merle parent — never merle to merle. Our program follows that standard without exception. Every Blue Merle puppy at Designer Yorkies comes from a single-merle pairing.

What Blue Merle Yorkies look like

The merle pattern is unique to every puppy — no two are alike. You'll see:

  • Patches of dilute (lighter) blue/grey on the typical Yorkie blue-and-tan base
  • Possible blue, partial blue (heterochromia), or both-blue eyes
  • Often a small white blaze on the chest or feet
  • The same silky, hypoallergenic single coat as any Yorkie

What to ask any Blue Merle breeder

Before reserving a Blue Merle puppy from any breeder:

  • "Is one parent non-merle?" The answer should be yes.
  • "Has the merle parent been Embark-tested for double-merle?" Should be yes — and you should be allowed to see the result.
  • "What's your health guarantee on merle-related issues?" A confident breeder offers a multi-year written warranty.
  • "Can I meet both parents?" If the answer is anything but yes, walk away.
