When our housemaid left us for a job abroad, our pug looked lonely and seemed to have lost its appetite although he eats when cajoled or when hand fed. That housemaid had treated our pug like a son so maybe their closeness is what has caused our dog's loneliness. When our housemaid was still here, we noticed that the pug would always be by her side. When we arrive home, our 2 other dogs would go gaga over our arrival but the pug was not that avid. Obviously, we are just friends to that pug and not its master for his master is our housemaid. But that was 2 years ago and now our pug seemed to have his loyalty back to us.
