When you were asked to housesit, did your boss mention specifically what she wanted you to do...feed the dog, take the dog for a walk, let the dog out couple times a day? I would just do what she had said she wanted me to do when she asked me to housesit. If she didn't mention the daughter would even be there, I wouldn't think she would expect you to be a wake up service or even cook dinner? If the daughter does have issues with you, and gets mad, I would be just calling up her mom and explaining that this goes far beyond what you thought and she might be needing to have a little "chat" with the daughter. If she is old enough for her mom to leave her to go on vacation and she didn't make arrangements for you to "babysit", I wouldn't!!
Sounds like the dog was your "job", not the daughter

Geeezzz, some people, and how messed up is that to pay a 35 year old woman to clean the kitchen for her own parents? People never cease to amaze me sometimes
