[nagdu] Chocolate labs

[Ann Edie]

There was an article a while back which described the genetic relationship
between the different Lab coat colors.  As I remember, it is not as simple
as just one dominant and one recessive color, but depends on the combination
of genes in each parent for several generations back.  But as I recall,
litters do include pups of different colors, including chocolates with
another color in the same litter.  But I may, of course, be remembering
incorrectly.  I'll try to find that article on the web.

However, I do know, for sure, that TSE and Guiding Eyes, at least, have and
do put out chocolates as  guides.  My first guide, Bailey, was a chocolate
Lab, bred and trained by TSE, and he was very mellow and responsible, and
was an excellent guide for nine working years.  And he was definitely bred
for temperament and other working characteristics, but was a lovely
chocolate color to top it off.  As I recall, I was told that several of his
littermates also made it successfully through guide training and placement;
I don't know their colors.  Bailey was the only chocolate in our class.  He
was a holdover from a previous string, so his littermates probably went out
before he did.

Best,
Ann

I was told Chocolate Labs were bred purely for their color, not temperament
or behavior.  As with any dog, some chocolate labs are fine but many have
issues, temperaments and behaviors that do not make them viable guide dogs
worth breeding for programs. The larger, better established guide dog
schools, who have their own breeding programs, breed for health,
intelligence and disposition.  Chocolate labs are not born in black or
yellow litters.  Black is the dominant color, yellow is recessive and Black
and Tan labs are a genetic mutation that only effects coloring.   Donna
