Ok, this is an odd thing. My 8 week old ShihTzu ( I have had her one week) is good sleeping all night, except on days I am at work (2 days a week) she eats later and then often goes poo on her training pad around midnight. This is when she will typically bark. Maybe it is before she eliminates, maybe after. I am sleeping, wake up and try to ignore her whine/bark thinking she will go back to sleep. When I do get up (once she is quiet) I find she has eliminated on her pad. Should I be getting up sooner as I think she is alerting me she needs to go and for some reason doesn't want that in her ex-pen on the pad? I am confused by this situation.
