I have been litter training my puppy. She is just about 4 months old. She was doing really well - I would see her run to box to go poop but all of a sudden she is having accidents everywhere. She will poop right next to her box but not in it or she will go hide from me and poop there. Why does she do this when she knows where she should be going? We just moved to a new apt. which may be confusing but the box is still in a very visible place and she usually goes there to pee but hardly ever to poop. Anyone have a similar situation? I have heard this breed is hard to train but about what I age is pretty normal for them to be accident-free? Thanks for any advice.
