My pet dog

Pleae help me to correct them, thanks!

I have a pet dog. I named it Doggie. Doggie is a white coloured shepherd dog. it is very lovely and It always licks my cheek. Doggie had been trained before ehile it is in the pet dog. So, it knows how to go back home, sit, stand and stay.

Doggie is special to me because it is just like my best friend. everytime when I come back from school, it will run out quickly to welcome me. it will jump onto my arm and lick my cheek. when I am free, I will play with Doggie in the garden. it will lie down on my feet, roll over and squirm around me until I give it a stomach rub. I am happy to have a friend who is never busy and can always play with me when I am lonely.

Besides, Doggie is just like my family safety guard. it will always help us to take care of our house. I remember that once there was a thief who tried to steal something valuable from my house. On that night, all of us were asleep. None of us noticed that the thief had broken into out house.

Luckily, we have Doggie. Doggie barked at the thief fiercely when it noticed the thief. It helped us to chase away the thief. All of us were as happy as a lark because nothing had been stolen by the thief.

I am very happy to have a pet dog like Doggie. I believe that caring for animals is important. So, I promised that I will take good care of Doggie forever.
