I have to admit, that post startled me also.
I don't want my dogs to "fear" me, but I do want them to know that I am the boss.
I don't have two Basenjis, but I do have two dogs. If they "argue" over a toy, and if the arguement doesn't become violent, I let them work it out.
If they actually get into a fight, which has only happened a couple of times and not any time recently, I use something {broom, etc} to push them apart, say "NO!!!" or "STOP!!!" and the aggressor gets locked in her kennel for a few minutes. If the fight began over a toy, that toy gets put away for a while.
If she gets snarky when released from the kennel, back in she goes.
Really, in the two years we've had Jazz they've only actually gotten into maybe three good fights. Jazz seemed to catch on quickly that that kind of attitude will get her nothing. And certainly won't win her the "prize" of the disputed toy. No way. No prizes for winning fights with her "sister".
I know many won't recommend this method because of the danger of being bitten while picking up the offending dog, but I'm pretty good at scooping up a wriggly Basenji-sized dog and holding it in a way that doesn't allow the teeth to get near me { hip on my hip, hand on shoulder}.
Although, Jazz has always been pretty careful about NOT biting at me when she's trying to get to Gypsy. {Jazz is always the aggressor in their disputes}. I think she learned early to be careful when she was young and the dogs got into a spat and my daughter was in the middle {it involved popcorn, and well, Jazz loves popcorn, thought Gypsy was moving in on it…..}. Jazzy did get a good nip on my daughter's arm {actually bled} and SHE seemed more startled by that than my daughter did! It was clearly accidental,and she's been very careful ever since.
Being unreasonably snotty with the other dog gets her kennel time. No discussion, just scoop, lock, and walk away. Works with her.
