I just had it re-assured that basenjis are partly just a 2-3 year old child. My roommates kid is visiting, and his mom is having the same arguments with their 3 year old son as I have with Medjai.
"You just played, now you MUST go to the bathroom. I know you don't want to, but trust me, you have to."
"Take a nap, you played all morning, and you always want to play later."
They both will just look to see when the parent isn't looking and do what they're not supposed to.
I always tell people that having a Basenji is like having a perpetual 2 yr old….so actually, you give Medjai more credit than I give mine, LOL.
