can you offer any advise, i have two female tibetans, 18mnth and 12mnth, my problem is that they are both still not house trained of a night.  also during the day if the door to the garden is shut, they will do it the house. The last couple of days one of them as taken to peeing on the rug in the living room. As i am moving house shorly where it is all carpeted, and the previous owners have a male dog,  I would be very gratefull for any advise.  I have tried praising them when i have see them doing somthing in the garden ,but to no avail. look forward to hearing from anyone that thinks they might be able to offer any help.
