Favorite animals

I like animals very much. For example dog, rabbit, koala, and so on.
But I like dog the best. By the way, I have a pet. Let me introduce my pet. He is a black dog. His name is “Chiro”. He is small but cheerful dog. He is about 5 years old. He came my house when I was a junior high school student. We hadn’t pet since then. We anxious about how we grow him. But he grew. He is very noisy, so we are annoyed by his bow.But We like my pet “Chiro”.
