S- category: Landseer colour
originally written by: Marika Mäntylä
In basics, it's is very alike to the hereditary of the brown colour.
SS= black dog which does not carry the landseer-gene (though the dog may have white on the tip of the tail, paws, chest..)
Ssp= black dog with the landseer gene.
spsp= landseer coloured newf.
If you cross two landseer newf together, the whole litter will be landseer coloured.
If you were to cross a black (SS) with a landseer, the whole litter would appear black, but they all would carry the landseer gene.
If you were to cross two black newfs that carry the landseer gene, at least in theory 75% of them would be black and the rest, 25%, landseer coloured newfs,
Newfs that are either BBspsp or Bbspsp carry the landseer gene. bbspsp is a brown&white newf (born 1 per year in the world) BBddspsp is a gray&white newfoundland (in finland only 3 landseer ECT's born in total).
Irish spot- Happy Adventure Maggie
The amount and situation of the white's on a newfie vary a lot. An sisp dog will have a lot of"irish spots". The same combinations that produce sisp dogs, produce also spsp-dogs. swsw dogs have too much white. The genotype of the dog cannot be predicted only by watching the dog, the different genes that produce the white are almost impossible to define, since the dog may carry many different types and they may mix.
The breeding of ideal coloured newfoundlands is rarely possible.
swsw + R gene produce white boxers, and
with boxers, blue eyedness and deafness are related to the colours.
Although, the risk is only 8% higher than in other colours.
