My Dog

    My dad bought me a dog on my birthday. It is a male golden retriever dog. I really love him as my pet. His name is Jiji. He has brown fur. His fur is really soft and he likes to be rubbed on his belly. He has a long tail and a big body. I always take him for a walk around because he really likes it. Jiji is already a part of our family.
