Australian Shepherd

We are exploring the option of rehoming our 10 year old Australian shepherd. She is extremely loyal. Due to her anxiety around our son, and 2 years of exploring all avenues of ensuring she is happy, we have decided to see if there may be a better home for her. She has a clean bill of health with all recent tests and blood work showing so. She would do best with a good sized yard and a stable home with no young children. She has a herding instinct so no cats. She is good with most dogs, but prefers lazy dogs to lounge with.
