Dogs are not children and don't understand physical abuse.
When you hit any dog, it feels frightened and confusing. It can't understand why the leader of the pack wants to hurt it. The dog starts to mistrust your physical actions. Then, you'll experience great difficulty in handling your pet.
A dog may retaliate due to its survival instinct teaching it to do something for defense. Any dog has quicker reflexes than a human being. It is also much stronger and dire consequences will result if it decides to attack us. The dog may become aggressive out of fear. This type of dog is a dangerous dog, especially around children who may provoke it out of ignorance.
A better way is to attend an obedience course together with your dog. Techniques are demonstrated on how to behavioral problems. It is strongly discouraged to use hand gestures with your dog. To the dog, a hand gesture is threatening. The way to an abuse-free relationship with your dog is knowing the key to eliciting desirable behavior with positive reinforcements like praise and reward.
Dogs learn with positive reinforcements. The more you reward for positive behavior, the more it remembers that this is the desired behavior to please you. You can start by praising and rewarding your dog for the little good things it does. If you take good behavior for granted, your dog doesn't get any positive reinforcements or attention from you so it may turn to naughty behaviors to get your attention. Scolding it is like rewarding it with your attention so the dog learns that bad behavior is desirable as it gets your attention.
When your dog learns that good behavior gets good attention, it will naturally use good behaviors. It is the inherent nature of dogs to please their leader or human master. Avoid continual nagging or reprimands at the dog as it will get accustomed to scolding and these will not mean anything to it. When correcting a dog, immediately show it the correct desired behavior. Reward it for this to motivate it.
Use your voice alone to stop your dog from engaging in wrong behavior. Scold only when you catch it red-handed. Don't touch your dog while you're scolding it. This prevents it from fearing your hand or launching defensive moves on you.
