After reading some topics over the past few days its made me interested in colour quirks or mutations/ non standard colours that can crop up within different breeds of dogs. Unless you are within a breed you may not have come across said mutations and iv been taken by surprise and google a few after reading some posts on here...... so I have decided to start this thread out of pure interest.

Bullmastiff

Long Hair- http://advisory.bullmastiffinfo.org/medicine/cosmetics_longhaired.htm
Dudley- http://advisory.bullmastiffinfo.org/medicine/cosmetics_dudley.htm
Pied- harks back to the breeds origins and sometimes a pied pops up
Black- essential a brindle with poor markings but appears to be black

feel free to add your own breed.

My Bullmastiff boy is a dudley without a doubt. He is a light fawn colour with a wonderful reddish/chocolate brown muzzle, he has amber with a hint of green eyes and a liver nose. I know he is not genetically a correct colour but he is gorgeous! He gets alot of attention as people wonder what he is! He looks too pale for a Dogue de bordeux and obviously people look at our Bullmastiff bitch with her dark mask so it confuses them! In the litter there were many 'correct colour' pups and about 3 dudleys. He has the most wonderful temperament and is actually soppier than our bitch (this may be a male thing?) Would be nice to know if anyone else has one. :)

Very few people know about the colour mutations within dobermanns.

The breed standard actually allows four colours - black and tan, brown and tan, blue and tan and isabella (fawn) and tan.

There also "white" dobes (albinos), which are most definitely not allowed and rightly so, being horrifically inbred (all descended from one female born in the 70s, bred to her offspring and them to their siblings/offspring and so on).  They tend to be white with cream points, and typicall have blue eyes but can have pink.  The blue eyes are why a lot of people call them 'white' - they believe that albinos can only have pink eyes (not true, partial albinos such as the dobes can have blue).  They are prone to sun damage, photosensitivity and temperament problems as well as the usual raft of dobe health issues.

From time to time all black dobes crop up as well.

Looks-wise of course there are variations in ears and shape - one of mine has ears like a manchester terrier while the other two have 'normal' floppies :-)

We have mismarks in Cavaliers ranging from a splodge on the muzzle to a completely brown half face. I once saw a picture of a virtually all white Cavalier, should have been a tri as he had just one tiny spot on his body and a few strands on his ear. And of course the wholecolours often have a bit of white on them.
