Caesar used to do this around 1-1/2 yrs old. The trainer told me to ignore it, that it was negative attention he wanted. I quickly found out that if mom walks away from basenji. Basenji gets to bite her butt! LOL.
My answer was Basic Obedience training. Not only to communicate better, but burns that energy. I also found a 15min walk did the trick as well.
You can use Cheerios as a treat and spend 15min on tricks for indoor play, or do like most of us do and multiply…..
Basenjis seem to need more play time than basenji parents have once you get home from work, clean up, settle down, make dinner, and clean up again. Multiples will burn that extra energy but the basenji 500s never end....:D
