(3 yrs old) Good with kids, cats and large and small dogs

Hello, my name is Garren, which means Guardian and I will protect you. I live on a horse farm with my foster mom but she says that I cannot be around farm animals unless I am on leash because I am too obsessed with them. I love my three grown German Shepherd brothers and my little sister, Kitzel. We play and have fun although, I do have to be observed because I get so excited when I am playing.  My foster mom says that I run like a Gazelle:-).  I am mindful in my huge crate and I don't mind going into the outside kennel, but I had rather be beside my foster mom. She says that I am so intelligent and I always try to do just what she asks. I have an enormous amount of energy and I will need a very German Shepherd savvy owner. By the way, I love to swim, I take a walk to the pond every day with my family and I swim laps. I surely would love a forever home.
