Your doggy is adorable.
She is a mutt, though. I'm not saying that's bad, I've ALWAYS had mutts, not purebreds, but I just want to explain that breeding a Silky Terrier with a Yorkie doesn't create a new "breed."
The reason most people here don't like the so-called "designer breeds" like "yorkie-poos" and such isn't because they don't like mutts, but because they feel it's irresponsible to purposely breed mutts when so many are dying in animal shelters every day.
Also, most backyard breeders don't do any health checks on the parents. Frankly, I'm shaking my head at this woman saying a tiny dog like this would be able to rough house and wrestle with the kids. Small dogs are fragile and can break bones easily!
PLEASE have your dog spayed (if she isn't already) when she's old enough, you'll both be happier in the long run.
