@Chealsie508:
Eeefarm- I read that article as well and while Oakley isn't having behavioral problems that I attribute to his not being neutered, or humping, I am dealing with him resource guarding me. I don't think neutering him will change this as it's not hormonal.
Yes, I am aware of the other thread. What struck me in the article I quoted was the assertion that neutering could cause aggression!
In my experience, Basenjis are seldom into humping humans. Personally I wouldn't be doing unnecessary x-rays. Since you would prefer to wait a bit, just do that. Unless you are under contract to neuter him sooner, I wouldn't be pushed into getting it done now. Your friend is right, a dog's a dog, but Oakley is your dog and she needs to respect that. You have to make your decisions based on what is best for him.
