Havanese and Havashu dogs and puppies come with different nose colors. The main two are black and brown.
It is the nose color that identifies a "chocolate", not the coat color.
Chocolate with brown hair and white patch
Tricolor black with tan and white points
Dogs' noses can be pink, brown, black, gray or even white. Havashu dogs usually have either black or brown noses.
The genes that produce chocolates are recessive, meaning that both parents have to carry the gene for the trait to be expressed (to show in the dog).
The skin ("leather"), eyes and pads' colors are also determined by this gene, and will be lighter on a chocolate than on a standard Havashu.
Other recessive genes include those for cream, black and tan, and red coats, and for sable hair.
Havanese coats can be black, silver, chocolate, red, gold, champagne, cream, blue or white or dilute (lighter) versions of any of these. They can have dark dorsals or saddles and tails, points, masks or spots,
They can be sable (individual hairs have a dark tip), brindle (striped) or solid colors. Depending on the distribution of color, they may be labeled as Irish pied, half and half, particolor or piebald (just the crown of the head is a different color). And their hair can be anything from straight to wavy to curly.
With so much variation, and the tendency for puppies to change color as they age, it can be difficult to choose a pup based on color. But regardless of the color of their fur, these puppies are sure to please.
