One of my horses has been eager to play with every dog he's met. His version of "play" is treating dogs like they treat squeaky toys. The largest dog he's yet met was a bullmastiff and he didn't hesitate for a moment. He's also accustomed to working cattle and will chase even a bull if I ask him to.
I do wonder how he'd react to Odin, though given his history of chasing bulls, I suspect he wouldn't hesitate.
