predominate which is more than 51%. The word predominate clearly means overwhelm
not as some imagine a marginal percentage. White and tan are the most often
seen, but the Tri colours (black, tan and white) are starting to emerge again
after being rare in the early 1990s. They have always been part of the Jack
Russell breed. The white, black tan and brown come in many patterns and varying
mixes of individual hairs, regardless of the shade, dogs are classed as plain
tan/white or tri.
Speckles or ticking are sometimes found. This
is not a fault as such but is not encouraged. The same applies to Fox Terrier.

dogs are white with tan patches - tan may include all shades of tan from lemon

another and the dog is the same shade all over (white the exception of normal
pigmentation variations, ie, slight lightening over cheeks/eyebrows/forehace,
darker hairs on ears etc. )

have some all tan patches as well as black patches, but the head of the

In other breeds this colour is often called sable/white.
A true tan/white(bruwn) is so dark in colour as to appear black and follows the
same tan or lighter shadung pattems as found in r\tricolours. Occasionally,
the head is tan and the body patches near black. Usually the undercoat is tan,
and the outercoat a mixture of black hairs interspersed with than.

The sabling of the tan/white

and Parsons Terrier . All Jacl Russells registered with the ANKC (bar those
descending from recent imports and those transferred from the JRTCofA Inc,
registered with a pedigree category of "100% imported bloodines) are known to
trace to early Foxing Terrier and will carry the genetics of the common colours
that appear in those breeds. I know of no@brindle Jack Russell in
