Teaching a Young Dog New Tricks

I am learning plenty of new tricks. My immense brain gets so bored that I must humour my Minions and learn their commands to entertain myself. Here's my report card for the first 1/2 of my year:

Good tricks
- Sit
- Stay
- Come on whistle
- Fetch toys
- Drop said toys
- Shake paws/hands
- Do business (not really a trick, but I can go more or less on command if I need to)

Could do better
- Stay command when Minions have walked more than 5 m away
- Catching frisbee before it hits the ground (I almost had it today but it hit me on the head a few times)

Fail
- Lie down (I still have no idea what the Minions want me to do here!)
- No jumping on plates/laps while Minions are eating

Overall Grade : B+
