Vegeta greeted me at his gate happy to leave his kennel. When we reached the interaction pen, he spent most of his time with me in the shade. As I was scratching the middle of his back, I found his "sweet spot," and he loved that. He also liked getting on my lap and giving me hugs. I later learned that Vegeta came in with his neighbor Goku, and they're from the same home. That would explain that whenever one passed the other's gate, they wagged their tails and wanted to touch noses.
