We are getting a considerable amount of 'black seal' colored puppies. Solid, abstract and parti.
Seal is currently a complete mystery. Seal colouration makes black dogs appear brownish (with the nose remaining black), varying from a slight brown cast to a shade almost as light as liver. There is often a black stripe down the back, and the legs and tail generally remain darker than the main part of the coat. Seal dogs are born brownish whereas bronzing develops with age, and remember that a black seal will always have a black nose regardless of how light and brownish its coat is.
No genetic research has so far been conducted into seal, so it is unknown how it is caused or which locus is responsible for it.
Current theories include seal being an allele on the K locus (recessive to K, potentially something like a faulty K allele that works in a similar way to brindle), an allele on the A locus, or a modifier on an unknown locus that causes the A locus to partly show through on Kk dogs.
What does seal look like? The black appears black until bright sunlight hits the coat, and then it has a reddish cast to it making it look almost brown. That said (and as far as we know), a black seal dog will always have a black nose, regardless of how brownish its coat appears.
PARTI IS BASICALLY A WHITE DOG WITH BROKEN PATCHES OF COLOR. EVERY PARTI IS MARKED DIFFERENTLY IN BOTH THE COLOR PATTERN AND PIGMENT. THIS FEATURE MAKES THEM ALL THE MORE UNUSUAL.
TUXEDOS WILL USUALLY HAVE A WHITE BIB THAT MAY OR MAY NOT GO ALL THE WAY AROUND THE NECK, AND THEY HAVE AN ALL WHITE BELLY. THE WHITE WILL USUALLY EXTEND FROM THE ELBOWS DOWN TO THE FEET AND FROM THE HOCK TO THE REAR FOOT. HOWEVER, YOU CAN HAVE SOME VARIATION IN THIS WITH ONE OR TWO LEGS NOT HAVING ANY WHITE AT ALL. SOME OF THEM HAVE MARKINGS IN THE HEAD AND SOME NOT.
ABSTRACT IS CONSIDERABLY LESS THAN FIFTY PERCENT WHITE ON ANOTHER SOLID COLOR, WITH THE REMAINING PERCENT OF ANY OTHER ACCEPTABLE SOLID COLOR. THIS COLOR IS A SOLID COLOR WITH A SPLASH OF WHITE DESCENDING ANYWHERE UNDER THE CHIN OR NECK AREA AND CAN CONFORM ALL THE WAY DOWN UNDER NEATH THE BELLY AREA OF THE DOG BUT IT CAN BE A VERY LITTLE MARK COMPARED TO THE OTHER 90-95% OF THE SOLID COLOR, THIS CAN OCCUR IN ANY OTHER SOLID COLOR EXCEPT FOR THE WHITES.
