What happens if you hit a dog every day?

Beating a dog every day causes serious harm to its physical and mental health. First, frequent beating causes injuries—skin damage, fractures, muscle damage, internal bleeding—and can disable it in severe cases. Second, from pain and fear the dog gradually loses trust in the owner and may show avoidance, barking, or defensive aggression.

Also, from stress the dog may become very anxious and depressed, leading to behavior problems like excessive licking, tail-biting, or head-shaking. Finally, daily beating lowers social ability; the dog may be very wary or fearful of other dogs and people, unwilling to be approached and even showing aggression.
