To successfully train a dog you need what they call "high value treats" when it is new or complex learning. When just reinforcing normal behavior - like when they sit nicely and patiently and wait while you do something and you want to reinforce that behavior. It is important to remember that you want to teach your Bully what you want , not what you do not want. Nature abhors a vacuum, so anytime your Bully is doing something you like -reward it. Right now my 9 week old Buster likes to sit quietly at my feet when I make meals so I give him a little kibble now he knows this is good- mama likes this. This has transferred to sitting quietly for me when I ut his food down now. But for new learning high value treats are necessary. Especially since it is hard work learning new things - the reward has to be worth it. Patience gentleness and firmness kindness and boundaries are so important with Bullies. They do not respond well to aggression, anger, fear or harsh punishment. Redirect negative behavior, manage negative behavior, reward good behavior. And always be the leader. Good luck.
