Your relationship with your dog is an important one, not just for you but for him. It is even more complex that you have probably realized. There have been numerous studies that have shown that your temperament can affect how your dog reacts. At the University of Cambridge, Dr. Anthony Podberscek studied the varied personalities of the English Cocker Spaniel and their respective owners. During his study he obtained data that showed that owners who were more introverted, emotionally less stable and underdisciplined than the average person were much more likely to have aggressive Cocker Spaniels than people who had average scores for these above mentioned characteristics.
Although these studies show extreme cases, it does show how important the bond is between you and your dog. In an ideal situation, the relationship will be mutually beneficial. One in which you offer care, a safe environment, proper training and attention and where he can offer you his unwavering loyalty and companionship.
