That's awesome! How do you go about teaching "roll over?" Gemma's tricks have come naturally because they are all things she had just done on her own to begin with, so it was easy to associate them with a command. She only ever rolls over when she's outside rolling in smelly grass, lol. I have no idea where to begin with something like that!
Well she has struggled with this one for ages, so i gave her a months break and tried a new tactic...
I got her in a Sit, then a Down, then with a very tasty treat in my hand moved it from her head down her side to her leg, so her head should naturally follow the treat, gravity takes over and she rolls onto her back (this is when you say Roll Over). Move the treat accross her body so its at the other side, she should then get up and she can have the treat x
Ha well, Honey does that too! Just every time she tried to grab the treat or got out of her down, i put the treat behind my back and said 'Too Bad!' - so the food had disappeared because she did something i didnt ask her to do.
