I'd meet the animal before I wrote him off. A friend of mine has a coyote blend. She took her time getting to know me and is very protective of her pack, but she is safe off leash and very playful. But that's a domesticated blend, not a full coyote.

But from what I've read the Dingo also forms very close and permanent pack ties. Dingo's sound like an interesting animal. I like the 20 year life expectancy.
