From there you can go into a Protection Alert(non biting protection title), the "sport" titles or Police Dog titles. Starting with 1 and working your way up. In the sport titles, you have a choice of Suit, Sleeve, or muzzle. Depending on what you're doing the titles can have slight differences. If doing a P1 sleeve title, many of the exercises are still done in a suit except for the bites. So it is a good idea to expose your dogs to seeing a suit before the trial. Here are videos of the P1.
