A

The correct answer is D (run after the dog while shouting its name).

Explanation:

A dog off-leash can be difficult to retrieve if you don’t know how to do it correctly. According to professional trainers, the least effective method is to chase the dog while shouting its name.

This is because the dog will most likely think that it will be punished for returning or that you are playing a game.

To be successful in retrieving a dog who had managed to slip off its leash, you should offer treats and call the dog’s name in a calm and cheerful manner.

To prevent the dog from running away, you could purchase a dog harness, which is much more difficult to slip off than a collar.
