My name is Luna!

We need to rehome our 3ish year old German Shepherd, Luna. She is a great dog!! We feel that she would be better with someone who has some space for her to run around. Unfortunately the home we live in doesn't have a finced back yard and it's unfair to her.
A little back history about her:
We first got Luna from the animal shelter. She is spade and has her shots and has a chip. She is very very kind with kids and has never bit or had any issues with my kids. She is house trained and she will walk with a leash and she will alert you when she need to go outside. She can get a little excited when you first go out but calms down after you tell her to. She is crete trained and will sleep and stay in her cage when you leave the house or sleep at night and if you want the cage that we have for her you can have it. She is curious about other animals, we have 2 cats and she has never harmed them. When she sees other dogs outside she wants to play and she loves to go on walks.
