My pet

I have a pet named Lucky. He is a very small dog, and he is really smart. One of the reasons why i think he is smart is becuase since the first day he came to my house, i had taught him that when he is doing something wrong i say "no!" and he stops and looks at me, then if he is doing something really bad, i hit him a little bit in his mouth and i say "no!" so he stops and learns not to do it again. Also, i taught him to bring me the ball. Everytime i play with him, i throw the ball and he runs to get it, then i call him, and he comes to me with the ball. This two tricks that my dog had learned it took a lot of time for me to teach him, but now he is educated and that is proof that he is intelligent and obedient. I will try to keep teaching him more tricks because i want him to be a good dog.
