We have had our yorkie since January, she is 4 yrs old. It took a while for her to adjust but the previous owners said that is was trained to go outside, which she has done successfully until now. The last week she has gone in her confined area area, mostly poop. So I decided to buy a crate, last night at 1am, she was barking, she had gone poop in the crate. I just don't know what to do, thought there might be a problem with her digestive system, but she doesn't have loose stools. Someone help, can't figure out the change in routine.
