One of the biggest mistakes is inconsistency. If today you allow the dog to jump on people, and tomorrow you scold him for it, he will not understand what is wanted from him. The same applies to the "come to me" command - if you call the dog only when the walk ends, he will start to avoid this command. Another common problem is the incorrect use of rewards. Treats should not be a bribe, but a way to reinforce good behavior. If you give a treat every time the dog simply comes to you without following the command, he will quickly understand that the rules can be broken. It is also important to pay attention to the emotional state of the dog: if he is nervous or afraid, training will be less effective. The owner should learn to read his pet's signals to understand when he is tired or confused. Discipline is not punishment, but a system of clear rules. If the dog knows that he will receive praise for good behavior, and there will be no encouragement for bad behavior, he will begin to make the right choices himself. Education is a daily work that gives excellent results if you approach it with patience and love.
