If ur dog starts sniffing at da ground to pee or poop, a drum should sound. in that case DO NOT PULL THE DOG AWAY it will hate u. also the only way to be sure that u are coming up to a prezzie in 1 of da ? boxes, the music will fade and then u will get a prezzie!! also when a dog iz cumin up, the screen will go white and ur dog will lay its ear out and bark twice hope dis iz helpful!!
