Anyone who has got a bulldog can brief you up on how hard it can become when training puppy bulldogs. Bulldogs have an attitude of their own and an independent streak in them, which makes it even more difficult to bring them under control. You must hold the authoritarian position when teaching them rules, but you must be very cautious too, as slight aggressiveness in your part can bring out the hostile face of the breed and spoil all your efforts.
These dogs are amazingly smart and once trained can be one of most trustable companions that you can have, but in the beginning he may not be ready to accept your leadership and show his attitude in everything. The key is to hold your patience, train him for short sessions of 15 min/day and observe and pursue him in the right manner, so as to bring out his friendly side.
Keep your mood upbeat when training puppy bulldogs as this breed is extremely sensitive and is likely to pick up the mood that they observe in you. If you are happy, they are too!
NEVER extend physical punishment to your pup while teaching him commands as this can give him a wrong impression and force him to distrust humans forever.
