You can have it done then although personally i am going to let my Rottie x GSD who is just 5 months have a season first then spay her about 3 months later.
There are lots of fors and againsts having it done early, and i have in the past had it done as early as 6 months with no problems or changes in the dogs coat or anything else.
Will save you the mess of the season and unwanted attention from other dogs. But some do argue about coat is never the same etc etc.
I have a 10 month old JR Male that i had castrated at 8 months to stop any problems in the home when my bitch has her season.
Go with your personal circumstances and what is best for you and your dog.
