What's Wrong With Animal Rights

This essay has me confused now about what happiness truly is. The author explains happiness in human terms, and then went on saying animal rights group didn't understand what hapiness is to animals. I enjoyed the example used of the author's relationship with her dog Drummer. She showed how Drummer gets happiness from their trusting relationship. Due to their strong relationship she feels she should be the only person granting Drummer's rights. I'm not much of a pet lover so I didn't enjoy this reading.
