I agree. Caesar was pure chaos as a puppy. Once he was fixed and through the teething period we decided he was so out of control that we needed the Basic Training.
Once we completed the Basic Training we learned that we werent communicating correctly with him and he was an angel. We crated him while at work and at night as well. He didnt mind at all and Basic Training really is what did it.
Some dogs are naturally obedient like a shephard or collie. You can train them at home to sit and follow the basic commands. What makes the Basenji difficult IMO is that they are sight hounds and scent hounds which means they are always paying attention to the action. We did training in a Petsmart store with people walking by and lots of noise. It was really hard at first to get his attention to even start training. Once we found the stinkiest liver treats, it was smooth sailing.
Caesar was an indoor dog only for his first 3 years. We took him to the dog parks every weekend and he became very socialized.
He is 6 now and sleeps out of his kennel without any problem.
I truely believe the horror stories you are reading are true, and happen in the puppy years from people who do not invest enough time into their dogs behavior. You will have to commit to training a basenji if you want to avoid those stories. When I adopted Caesar I didnt realize this, if it wasnt for the Basic training, I would have lost my mind.
