With any dog that I have ever worked with, a simple rule is to be smarter than the dog when training. I think it's just that basenji's are that much smarter than other dogs that I have worked with. And the fact that they are much more independant in their thinking than other common breeds. It may not be harder for you to train them but I do think they take more patience and understanding than most other breeds. It is very easy to make a mistake with them and you must be willing to learn their needs.
It's not that I have written off the use of clicker training. I would love to learn a better understanding of it. I happen to like the success of the method I have used and am of the old school thinking that if it's not broke then don't fix it. The whole reward with treats idea has never worked for me, probably mostly because it goes against some of my core beliefs. But that doesn't mean I don't think it won't work. I don't believe it is the best way for me at this time. Largely because I am unskilled in it and don't have enough confidence in it.
I do not know how to apply clicker training effectively for walking on lead. But I do know first hand how well a pinch collar works for teaching a basenji to not pull on its leash. Before using one I thought perhaps I would need better understanding on how to use it but after trying it out on myself first, I learned that it took less skill that a choke chain and was much more effective. Before basenji's, I would say that a choke chain and about 15 minutes is all it would take for me to have a dog that would heel well. With my basenji I was constantly having to correct her with the choke chain and she just wouldn't "fall in". After moving to the pinch collar it only took the occassional correction and she got the idea and quickly found pleasure in her obedience. I look forward to applying the cinch lead that I now have the next time I need to train a basenji. It seems to work even better than the pinch collar but it's really hard to tell because she is already so well behaved from before.
As I said in my first post, I am here because I want to learn more. And that means that I am open to all ways that others are suggesting that works for them. I will enjoy hearing about all of the skills and techniques that others have that are willing to share them with me. Perhaps even a thick-headed old guy like myself can still learn a few new tricks, with the help of kind people from here.
