Have you ever come across a Black and Tan/red Irish terrier? I don’t mean black guard hairs, but true black with reddish/tan undercoat?  

I have had many litters but have never encountered this.  The picture does not show the red in her coat.  I call her Livvy for the olive ribbon at birth.  I can one million percent guarantee she is full Irish Terrier as my bitches have zero chance of coming into contact with another dog and I only have one male Irish at home. 

Livvy
