White Hair

Question
hi! i have a female labrador retriever. she is 8 months old. for a while i'm observeing that she is growing white hairs in neck, abdominal areas and tail.although lab shread hair but she is loosing hair in a greater rate. is there some sort of vitamin defeciency?please suggest some remedies.

Answer
This could be diet related.  As I said in my other answer, she needs to be eating a dog chow.  If there is no way you can buy one for her, the link I gave you gives links to a good recipe at the end.  It is also normal for a Lab to shed some.  Females shed just before they start their reproductive cycle, heat.
