If I saw any marking in the house, inappropriate aggression towards people or other dogs, I would probably neuter any time around six months.
Cara is 11. She has only love our Samoyed in her entire adult life. No animal is worthy of breathing air. While Pam did take her about 5 years ago for a refresher course, she learned to ignore the other basenjis, not like them. If she freezes, she is definitely waiting for prey. Usually she keeps walking slowly, eyes seemingly forward, until she is within striking distance.
I wouldn't trust my dog to lie in wait until you truly are sure of their intentions. Even then, do you know if their behavior may be stressing out the other dog? And how many dogs and how much time do you have to play out this behavior?
On a good day, Moose the Samoyed runs into up to 10 of his harem on a long walk (usually 3 to 5). He's out to play, that's the goal. On a potty walk when my daughter or her fiance are in a hurry, they give him very little play time and he accepts it. No, he's not a basenji...but also an ancient independent thinking breed. They live to play. We get to decide when.
My point being, I understand that a behavior may be normal...but I am surprised at owners throwing up their hands and letting it go. There are many situations where you need the dog to keep moving, and you want training in force before that occurs. I am not sure at the resistance against that view.
