We had sleepless nights with our Poppy for 4 weeks... She was locked in her crate in the living room at night and would cry all night long
she would poo everywhere (literally!
) and had to be bathed every morning. After 4 weeks of this I had enough... I took the basket that was in the crate and the dog and put both in the conservatory, turned around and closed the door!
best thing I ever did!!! little darling stopped crying and slept through or at least did her thing without tears! that's when we realised Poppy was claustrophobic!
crate training... through the window!
maybe your Poppy is like that too?
