Cassie is about 2 years old, and we picked her from a litter of her foster dog mama. She has grown up with kids, and treats kids she doesn't know very well. A new home for her would be someone very active who would spend a lot of time with the relationship. We cannot. She needs to run A LOT every day. If she is outside, she also needs a fence taller than 5 feet. She loves to run, explore, play tug of war, chase squirrels and bunnies. She is high energy, an excellent guard dog, very intelligent, and about halfway trained. House broken, responds when called, doesn't bite, but is exciteable and will jump on strangers to say hi. She is very difficult to walk on leash.
