Totally agree with you. Bloods are great animals. I have one that was really jumpy at first. Not a biter but just nervous. Now, I make a point to at least touch him every day, and I hold him a couple times a week. The nervousness is almost completely gone. Sometimes he doesn't even huff any more.

Interaction is key with these guys, I think. And consistency, too. You might be able to turn the corner with Sid.

Best of luck!
