Why you should think
twice before getting a blue Corso.... it's not just Corsos, its the
color. It's gorgeous but it has more health and skin problems than
any other color. Blues are beautiful but are a diluted form of
black and as such are a recessive gene that can cause life long skin and
health conditions. It is the same as blue Doberman syndrome, white
boxers, etc. The less blue in a line the less likely you are to
have problems but it's always a significant risk with any blue dog.
Below is an explanation of why this color causes a problem.
Color-dilution alopecia appears to be
the same disorder as Black Hair Follicular
Dysplasia but covers a wider range of coat
colors. It is also called Blue Doberman
Syndrome, Fawn Irish Setter Syndrome, and
Blue Dog disease.
Blue coat color appears
to be caused by at least two different
mutations in the MLPH gene in the 30 breeds
we studied. The commmon mutation causes
dilute coat color in most dogs that are born
blue or grey. The symptoms of this disorder
vary widely among individuals for reasons
that are not clear at this time. The
symptoms seem worst in Large Munsterlanders
but Newfoundlands, Doberman Pinschers, Great
Danes, Weimaraners, and Italian Greyhounds
can all have symptoms. Patchy hair loss on
the ears, head and along the spinal column
seems to be the most common symptom.
Dermatitis, wrinkled skin, allergic skin
reactions, etc. all occur. Some dogs are
free of symptoms early in life and then
develop them later.
We have collected DNA samples from blue
dogs with and without symptoms to try to
understand if the groups in each group had a
different mutation. However some dogs with
the common mutation and some without it had
CDA symptoms and others did not. There may
be a slightly higher chance that males may
suffer more severe symptoms than females.
