Great dog in need of new home

We adopted Cassie in 2017, and she has been an amazing addition to our home the last 8 years. We recently had our 2nd child, and while Cassie is not aggressive with him, she gets very excitable when he is near, and is worrisome to my wife and I she will accidentally harm him. Cassie was a very shy sheltered dog when we got her, and has transformed into an amazing dog with lots of personality and will kiss you to death. She is great with other dogs. She deserves a great home where she can have lots of attention and free reign
