Hitting a dog on the nose won't kill you. However, hitting the dog's nose will bring pain and discomfort to the dog and may also lead to behavior problems. Hitting a dog on the nose is usually a punishment, but this should not be the way to train a dog.

On the contrary, active training methods should be used to help dogs establish correct behavior habits. This includes rewarding dogs for good behavior and ignoring or preventing bad behavior. This method is not only more effective, but also has a positive effect on the behavior and emotional health of dogs.

In addition to training dogs, there are many healthy, enjoyable and rich activities that can make dogs spend every day happily. Dogs need enough exercise, such as walking or running, and intellectual stimulation, such as playing or training. Spending time and attention on the physical and mental health of dogs will help you cultivate healthy, happy and well-behaved pet companions.
