While you might find dogs that resemble an Irish Setter in appearance due to their coloring or size, they wouldn't be true Irish Setters unless they are registered with a kennel club as such.
What 2 dogs you mix with to get a Irish setter?
You can't get an Irish Setter by mixing two other breeds. The Irish Setter is a purebred dog, meaning it's a distinct breed that has been selectively bred for generations to maintain specific characteristics.
