Solutions for dogs eating randomly when going out:

1. You can buy a dog muzzle. You can put it on your dog when you usually go out.

2. You can choose to take your dog out while running. If you run, it will not have time to eat randomly.

3. When you go out for a walk, tie the dog leash. The length of the leash in your hand is just long enough to prevent the dog from lowering its head.

4. If the dog eats randomly outside, the owner needs to tell it in a stern tone that it cannot eat.

5. It may also be caused by pica, a lack of certain trace elements in the body. The owner needs to adjust the dog's diet and provide it with nutritious food to ensure a balanced nutritional intake.
