My Maltipoo puppy is only 8 weeks old, but he's really excited to learn how to do tricks...He's highly motivated by Fillet Mignon dog treats or just his regular dry puppy food...He's been trained for the last four days and he masters the command "Sit", "Hand Shake", "High Five", "Fetch", Spin", "Jump",...so his average is like 2 tricks per day...He's a fast learner and we're really proud of him ^_^
