Welcome to my bio everyone, my name is Nada. Ever since I was little, I have loved animals because they are so loving and kind. All they need is you attention, love, and care but I didn't understand them very well because I didn't get the chance to raise them. Well, That changed when my family and I got our first dog Rocky, a German Shepherd. Rocky was fun and loving with funny quirks. Being loyal and protective of us, he made me see the nature of a German Shepherd. Now, we have another German Shepherd named Mia. She is a wonderful dog and a rescue who just needed a second chance in life. Mia has long grown from being a terrified dog to the brave and caring German Shepherd that she is today. P.S: Here is a picture of our beautiful German Shepherd, Mia.
