@cherif Hi. You need to know that the Basenji tends to become emotionally attached, thus you can't keep her away from you, specially at night. (They were developed to fear the dark, and this is an inherited trait that’s difficult to break.)
regarding her "peeing" issue, you need to figure out what is the cause. In my opinion, she is doing so because you are away... but with time she will get used to your absence during the day. Here is a tip: Get her a Kong, and everyday, before going out to work, put some Peanut butter inside the Kong and it will distract her for a long time.
PS: share pics of Pipa:)
@tanza She is thank you ! However i have a small problem, don't know if you can help: how can you make her stay alone for 2 hours without crying her soul out, and without destroying everything in the Kitchen? Last night was her 2nd night alone in the kitchen and you don't want to know what she did... i think she was committing suicide lol... any recommendations?
