I'm dog sitting a shih tzu for 2 weeks while my family friends are on holiday. I have my own pug and he's absolutely fine with her. However since her mummy went away 24 hours ago, she has hardly eaten even though I've tried to keep to her feeding routine as much as possible, she hasn't had a drop to drink even though she's had 3 walks and she's just sleeping the whole time - no interaction at all. Is this just a case of the misimis mummy blues? And should I be worried about the no water thing?
