Purebred, German shepherd looking for a new home (Newbury Park)

Sadly, due to having to relocate, I am looking for a home for my German Shepherd.
Her name is Gigi, approximately 7 years old.
She is healthy, intelligent, loyal, and loves to go on walks and hikes.
She is is a sweetheart that loves being around people, and is also a watchdog that protects the home.
She is well trained and well mannered and walks well on a leash.
A recent visit to the vet shows that she is healthy and up-to-date on her vaccinations.
She is also neutered.
Gigi is no longer a puppy and does not chew up the backyard.
I am looking for a nice family that has a decent size yard and can spend the time that is required for a Shepherd.
Please understand that I need to verify that she is going to a good home because there are a lot of scammers out there who will take advantage of a free dog.
