My purebred maltese has black hairs around her eye!!?

I recently brought a 6 week Maltese, i've been told she's purebred and even viewed her parents! However she has a collection of black hairs above her left eye. See photo......
I have read that maltese puppies only really comein white with tan around the ears! Does this mean she's a cross breed?????

Both her parents looked like maltese!

Maybe. The only way to be sure you have a pure breed is their papers, which you didn't mention having. It is quite common for pures not to have papers - the owners happened to have pure breeds that mated. But its probably just an irregularity, similar to black spots on the tongue. If the black hairs are the only characteristic inconsistent with breed regulations, then she probably is a pure breed, with a slight appearance flaw. Normally, this would mean she can't be bred or shown, but again, you didn't mention papers, so you couldn't do that anyway.

By the way, adorable doesn't even come close. My God, that dog is gorgeous...

No

The word -- and the papers -- are only as good as the breeder. As you've said, I can find no evidence that black-pigmented hair is ever allowed in the breed. From one web site:

"Next, the coat. Is it pure white? A lot of dogs have lemon spots, which is acceptable, but anything other than lemon, or off-white markings, is not..."

The fact that the "breeder" sold you the puppy at 6 weeks old is also evidence that they were not good breeders. No puppy should leave its litter before the age of 8 weeks.

Hard to say if she's 'cross-bred', or that perhaps one of her parents is. As I said, don't rely on whether or not you got registration papers -- they are only as good as the ethics of the breeder.

Unfortunately, it doesn't sound like this breeder was very ethical.
