I think I wanna get a dog.
What are you going to do with a dog?
I will take care of him, feed him regularly
Dogs are great!  A responsible dog owner always cares and feeds his or her animals.
Actually, I really hate dogs.
It sounds like you're considering getting a dog on an impulse. If you don't like dogs, then you shouldn't get one just because the mood strikes you. A dog is a huge responsibility, and you should be ready to take care of it and give it love and attention when you get one.
