Havanese and their colors are fun...
Luna has a brown (but not very visable) area on her leg:
But I think thet will be silver sooner or later just like the rest of her body (except for the top of her head)
This is a pic of her at about 8 months old
As a tiny puppy
About 3 months old
Not enjoying picture time at 1,5 years (but shows the brownish color)
At 2 years out in the sun
If I remember right, the 1st places she started turning brown/silver were belly and (inside fur) of ears (the outside fur of her ears is black).
She never got all that brown, just had a short time where she was kind of silvery-blackish-brown (honestly, I do not know what color I would imagine if a person told me what I just told you guys) and then jumped to silver.
Now WHY do havanese sometimes turn brown before silvering out is an interesting question and if anyone knows, they are welcome to explain.
