Ever wondered what all of the color  
       combinations in Shelties were? 
                                            

 Markings can vary between each dog, They can vary with how much white they have for a collar, feet, chest, Muzzle, and Blaze. 
Whether your a Pet owner, Breeder or an inquisitive person by nature (such as Myself), I highly Reccomend the Book 'Sheltie Talk'. One of the Best books you will ever own!! 

Sable: 
Light Golden to Dark Mahogany Brown w/ White
markings. 

Tri: 
Black with Tan points and White markings.   

Bi-Black: 
Black w/ White Markings. 

Blue Merle: 
Blue (Silver/Gray color) with Tan Points and 
White Markings. Some Merle dogs will also have   
black flecking in the blue coat. Can have Blue Eyes or a Merle eyes.

Bi-Blue: 
Blue (Silver/Gray Color) without Tan points and
White Markings. Black flecking also Possible.
Can have Blue or Merle eyes.

Sable Merle:
Appears like the Blue Merle, only different shades
of Sable with  darker brown sable Flecks or spot. 
Some sable Merles will keep there Dark  
brown spots and some  will fade as they 
mature. Merle eyes are usually a good indicator as 
a Merle will only carry a blue or partial
blue eye. 

CHW: (Color headed White):  
50% or more white on a sheltie. Can be any  
color combination above. CHW Shelties are  
NOT to be confused with a Double Merle. A 
CHW  is simply a white gene. They are as normal 
as a  Sable or Tri.

Double Merle:
This is the result of a Merle to Merle breeding  
which usually will produce a puppy with mostly 
white coloring. Double Merle's are at greater risk 
for being deaf, blind or both. This should only be 
done by a seasoned breeder with knowledge of 
the color genetics. The resulting puppy can be a 
great asset to a breeding program but 
is not without risk.
