More: We got Nala when she was three months old, after she turned a year old we found out that she had Addison’s disease. She has a lot of anxiety takes a lot of medication‘s, but this does not keep her down. She is one of the best girls! I have two granddaughters, 11 months and three years old, she is so good with them so gentle and so caring. let me also point out she is my shadow, never leaves my side.
