How do you use ambivalent?

Ambivalent simply: having mixed-feelings about someone or something. It is used when something is very complex and you cannot decide on a certain stance. For example: I have a dog who is very energetic and makes big messes and he can sometimes be violent. I love my dog but he's making life a bit harder than it needs to be. In this situation I would be ambivalent about my dog. Sentence: I am very ambivalent about my dog, he gets very aggressive but he can be sweet sometimes.
