This is a small charm I used in order to bring someone I liked back into my life.
You'll need a small dog figure, preferably paper, clay (not baked), or rubber.
Something to consecrate or bless the dog with.
A paper and pen.
On the paper write out the person's name, and what the dog is supposed to do with that person (such as break a relationship, create one, etc). Bless the dog with basic "life" that you control. This is nota physical life, but more like a spirit dog that you are creating to do your bidding. Take the paper and roll it up, either put it in the dog's mouth or tie it around the neck. Stick the pin in the dog's leg somewhere. Tell the dog that the pin will only be removed once the charge has been fulfilled. Place the dog somewhere out of sight so it can do your biddings. Wait.
Good luck in your endeavors!
