first off Gracie2006, my Chloe looks just like you darker colored yorkie
we have problems like this wiht Chloe, she is just coming up on 5 months and we have had her since 8 weeks.
she does great and then boom accidents, and i swear sho knows cuz she runs and hides.
my only explination is that we have rearranged (gotten new furniture) and it messed up her space....it is funny because she comes ot me and trys to make up
anyway, i think i have not been concsistent enough.....maybe....i just nee dot get back to the crate more often, unless we are constantly with her, but even then is doesn't always seem to work.
as you can see i'm no help, and really just adding to yokie stubbornness *sigh*
