Pet Care Needed - Full-time / Part-time

My little puppy is 9 months. She half Maltese and half Shih Tzu. Her name is Mia, she is an inside dog that poop and peep on pads. She doesnt have eating schedule , she eats whenever she wants. She good with kids and other animals. She loves to cuddle and play fetch. She gets irritated when you play rough and when you raise your hand on her she gets upset. Besides that she mellow, really calm and quiet, she is a very sweet girl!
