In Frisbee Dog you need to click on the dog to start the jump sequence, release the dog when you think the time is right to jump in order to catch the frisbee moving overhead.
You need to also take into account the amount of power in your jump, the longer you hold, the higher you will jump. Time your jump in this way so that you catch the frisbee.
You need to remember you are a Frisbee Dog. You therefore need to be careful not to catch a hand grenade or studded dog collar. The hand grenade will blow you up and the dog collar will decapitate you!
It is time for Frisbee Dog... now show us what a good boy you are!
