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.
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.

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

Caring for others would ruin your life???
