Ink pens are best left in the desk or on counters well out of reach of Basenjis. And if you think you have something high enough out of reach you better move it back a little bit farther. I have observed my Basenjis getting things off of counters that I thought were safe- their paws are used just like we use our hands. Basenjis are notorious paper shredders. Tissues, toilet paper, paper towels, newspaper, homework, etc. are not safe if a Basenji is in the right mood.
House plants can also be a problem.
Not only in just the destructiveness, but also in the aspect that a number of house plants are poisonous and could cause your dog to become seriously ill or even die. A crate is a must for your Basenji. This is the only way to keep them from injuring themselves or destroying your home while you are gone. It also is a must in the car. Basenjis are VERY quick and can be out your car door or window before you know what has happened.
