I will talk about my favorite pet dog

First, dogs are smart, and we can also teach them some commands.

For example, if you are giving your dog food, say wait and the dog will wait for you to give him or her food.

Second, dogs are brave, and they can save people who need help.

Third, we can work with our pet dog.

For example, we can exercise together or run at a park together which is fun.

Overall, dogs can learn some commands that are helpful, save people, and work together
