If I have a dog, I will care about it.
Even staying with people who don't care about it will hurt me.
I would figure out what it wants, and I would really try my best to provide them.
It might ruin my life.
Therefore, I should avoid a dog.

In my opinion, people are more needy than dogs. Dogs seem to have simpler expectations than humans.

A dog usually wants a lot. It might be more than a person can give. People usually do not figure it out. They just feed the dog and lock the dog.
