Some examples of grizzle & tan colour

Grizzle & tan is by far the most common colour in Border Terriers today and varies from very dark grizzle to light grizzle with varying degrees of tan colouring from very rich red to pale tan.

Lettie above, she is quite a pale grizzle & tan

Maizie above

Bruce above, darker grizzle but still classed as a grizzle & tan
 

Luther above, another darker grizzle but still called a grizzle & tan

Young puppies are often quite dark, yet grow up to be normal grizzle and tans. The dark puppies in the photo are aged 3 weeks and grew up to be the same colour as Sniffy.
