pluto training update (slow)

Two months in and Pluto can sit when he sees food, but without food he just looks at me. Very dissapointing. I tried the hand signal method from YouTube, he just thinks I am waving at him to come closer and then he jumps on me. The trainer at the park said to keep sessions short, like 5 minutes, otherwise he gets bored. I thought I was doing that already but I think I did 15 minutes every time. Now I do the short ones and it is better, becuase he is less distracted. He learned come this week, finally. Ten treats for one good recal, I call it the Pluto tax. Still working on stay. He is only 4 years old, he will get it one day, I think.
