There ya go! He's comfortable putting himself in a submissive position with you, so I'd say you're doing a good job building trust.He is getting closer and closer to rolling over on his back for me to pet his belly, but it is his doing, not mine. I'm not brave enought to try to force him! Plus, when it's his idea, it seems like he's doing it out of respect for me instead of fear of me.
I think alpha rolls are ridiculous btw...unless you're a wolf.
