Help Bella get her ACL repaired!

Hi everyone! My name is Melissa, my best friend and roommate Megan's Australian Shepherd Bella was walking along the river in Fort Collins and somehow tore her ACL. We went to see the veterinarian yesterday and found out that she is in need of surgery to repair it. This news really came as a surprise, not only was the extent of the injury a surprise but the cost to repair it. Anything will help!
