In the video, I do see a lot of basenji traits, but who know... some mixes look like nothing they are really related to. Some basenjis, espec mixes, can be quite large.
I used to always take Senji with me to the nursing home where my grandmother stayed for 1 1/2 years before she passed away. They allowed people to bring pets in to visit. Senji knew exactly where grandma's room was, even though it was down at the end of the hall. He also liked to jump into bed with grandma's roommate, who was a middle-aged stroke patient. He never got snarky or nippy at any of the other residents. It's like he knew they were old and disabled. The only time he's act up would be when he'd encounter the resident cat. 😃
