I have a female havanese who was a cranberry mocha color turned white. What health problems should I look for?

Paris was and is a lovely ***** who is now a year old but I would not want to breed her if she has problems I'm not aware of. She has the brown pigment so has the chocolate gene. I've heard of some problems and want your insite on the matter.
Answers:
Do you have pictures of her, before and after the color change? The "cranberry mocha" throws me off...but if her pigment is brown, it probably is b/b at work. I'm not completely certain what to think about turning white. Although, I know some breeds carry a recessive gene known as "graying". For example: Yorkshire Terriers, Poodles. I'll have to look into it more, but my guess is she has the gene. Well, actually, two copies of it...one from the sire and one from the dam. Otherwise, it wouldn't 'show'...it would be carried/hidden. Again, I don't know what to think about the problems you were told about...what exactly was said? Are you certain it's color related...and not line or breed related?
ETA: Yes, Havanese have the "graying" gene. I found a website that states "SILVERING GENE - The majority of Havanese carry this gene to some degree." Graying/silvering...it goes by both names. Here's a link (it's toward the bottom of the page): http://www.cornerstonekennels.com/havane... and found another website http://homepage.usask.ca/~schmutz/diluti... Oh, I stand corrected though, it's apparently a dominant/partial dominant gene...not recessive.
Can you tell me more about the "problems" though...?
She is fine.usually when animals get older sometimes thier coat changes colors...so maybe that could be it!!
