The Lucky Collar in Nintendogs is primarily obtained by discovering it during walks with your dog.
Obtaining the Lucky Collar
To acquire the Lucky Collar in Nintendogs, the most common method is to take your dog for walks. While walking your dog around the neighborhood, there's a chance they will discover various items on the ground. The Lucky Collar is one of these items, though it is considered an uncommon find. This means it may not appear on every walk, so persistence and frequent outings will increase your chances of finding one.
When your dog finds an item during a walk, they will often stop and indicate their discovery, prompting you to pick it up. The Lucky Collar, once found, will be added to your inventory.
