Have you ever assessed yourself as a dog owner?

I try to be a good owner but there some times that bad things are inevitable.

According to most books, it's often the owner's fault for having a highly reactive, aggressive or dominant dog. It's either the owner lacks the leadership skills or he/she wasn't able to establish proper boundaries from the very start.

I see some people lead a calm and happy life with their dog and keep asking myself, have I done something wrong?

Have you ever asked yourself questions as to why your dogs got the bad behavior?
