When to spay a Giant Breed Dog?

[4 Dog Mother]

My daughter Christy had her Great Dane spayed at 8 months. She is now 4 - mabye it is too early to tell but she seems to have grown up fine. Her vet had recommended after 6 months.

Thanks everyone for your opinions and advice. I am currently trying to get ahold of the breeder. My vet suggest to do it as early as 6 months. So I will see what the breeder has to say. I just want what is best for my little girl. I googled to look for info, but didn't find any concrete info, just a bunch of opinions. So if anyone knows a good source to go to I am all ears. Thanks everyone for your time.
