Instructions
Grab the dog's shoulders and make eye contact. Be as gentle as possible with your dog. You want the dog to respect your strength, not fear you. A fearful dog can often become more aggressive and act out by urinating or even biting.
Roll the dog on its back, holding it by the front legs. If it struggles to get up, continue to hold it firmly until it relaxes. Make eye contact; in pack animals only the alpha, or leader, is allowed to make eye contact. You want to make sure your dog knows you're the dominant animal.
Hold the dog on its back until it calms down or stops squirming. Wait for it to show some sign that it respects you, such as a side-to-side tail wag or relaxed body.
How to Train Dogs by Putting Them on Their Backs
Putting a dog on its back to train it is a technique that is discouraged by dog trainers, although it can occasionally be used when a dog is threatening or violent. The tactic, known as an "alpha roll" is designed to make your dog understand that you're the boss and must be obeyed. Unfortunately, in the animal world, the only time a dog puts another dog on its back is when it's about to kill it.
