Dogs are popular animals that people like to keep them. Since the past, people have used them for taking care of other animals like chicken, cow, sheep and etc. Also, police use dogs for finding drugs. Because dogs can feel the smell of drugs and they are too useful for them.
On the other side, some people keep dogs called pets. These people often keep pets for fun or some other reasons and they enjoy this job. Also, they must pay too much money for keeping pets like dogs.
The truth is, I don't like to have or keep pets and I only like to see animals in nature.
