I have a shih tzu one and half year old who poos at night, I walk her 2twice a day, I don't feed her after 6pm and I let her out in the garden before I go to bed, I tried putting her in her cage at night but she just poos in her bed and howls and cries so now she sleeps in the kitchen with my other dog. She doesn't do anything through the day when I am at work. I am desperate for help as I have 2 small children and considering putting her in a rescue centre
