My new pet has about 70 words.

Hi, I'm somebody. I have a new pet. It is a dog. This is a very good one. It has a small nose, a small mouth and an hour suit. It has big eyes and big ears. Its legs are short and its tail is short. It is brown. On Sundays, I often take it for hiking. But from Monday to Friday, I have to go to school because I am a student. It is a puppy. I don't know if there is any mistake.
