How old is he? My girl Pipet was great at potty training and the bare basics, as a 1,2,3 year old she was very bitey, not in a mean way, but those little teeth are and were sharp!! She was trained to the phrase…."BE NICE" and you need to say it with only slight force behind it as any more is considered a challenge. If she kept biting I would wrap my hands in a pair of socks and make it clear that with socks, it was play time, without, it was BE NICE or you get no attention. She learned VERY fast. Sit and stay are not in the basenji dialogue until they are at least 3 year's old in my experience though I know they are all different.
Pipet uses standard language commands, I taught her to come, sit, stay, by saying COME and whistling a distinctive 3 tone blast that is unmistakable. She was trained in a graveyard where she and I walk and she can run lose. As for sit, well "SIT" is the word and it just taes time and patience, but there can be NO other distractions. I say WAIT, no matter if she is 1 foot or 200 feet away she stops and freezes as long as I repeat the commands about every 8 seconds. This obedience only came with age though. Until she was 3 (now she is 5), she had to be on a leash with a harness, no collars as she would slip out of them with a single pull. AND UNDER NO CIRCUMSTANCES CAN YOU YELL AT HIM!!! A Basenji will not be backed into a corner under any circumstances.
Take Diesel away from the house to train him, my two have always learned the most when on long walks. This was true for my first Basenji (a male) and is now true for Pip. The biting should be cautioned by the BE NICE command as they react if you say OW! Because they do not intend to hurt the one they love.....but if he is young, I really suggest you go for the sweat socks and make it a game. Like the books say, Basenjis are like cats, they play like cats, they ignore us like cats and they sleep with us like cats. I let Pip be herself and demand that she also follow my rules and she is so good, so obedient now that I am amazed with every passing day. You can see her on Youtube under "Pipet the well trained African Basenji"
I have a male(unfixed) male purebred basenji named Diesel. My fiancee and I got him from someone in minnesota who assured us he was great with kids(toddlers, babies) etc and was very docile and that he was already trained. I did teach him the whole potty training thing but i've been trying for three months to get him to sit stay or even listen to me for that matter. He has started biting him and I hold no power over him except i'm the one he wants to sleep with at night.(He's not allowed on the bed.) I'm getting frustrated and need help. I'e looked over every forum, tried practically everything and nothing is helping.
