Know your breed. Bulldogs tend to be very stubborn by nature. You can call their name endlessly and they may just sit where they are and look at you until you make it worth their while. Their stubbornness can also make leash walking a battle of the wills, and with their muscular physique pulling you their way, you may find yourself giving in a good deal of the time. Coming to the terms with the fact that you have a stubborn dog, should help reduce your frustration in trying to train them. Accept them for what they are and work with it.
