Answer
Well, she's a larger breed. She may not come into her first heat until she's a year old, or older. She may come in a little bit earlier than that. If you're going to have her fixed when she's 6 months old, then you should be safe. Some vets will perform the spay surgery on a puppy when they're younger than 6 months old. You may want to ask around and see if a vet around you would be willing to do that.
