Any dog gets the taste of blood can be trouble. Another dog, goat, calf, ... could be next. Don't get me wrong Dog's eat cats, and I'm fine with that but if they're chasing bigger critters that can be a sign of trouble. Sounds like the fawn was smaller than he was. Most dog's that are close to people won't attack in that manner, sounds like clod might be a bit of a loner.
If he didn't kill the fawn your probably ok, if he did, ya might want to keep an eye on him.
In the end it comes down to how agressive and NUTS the dog is. If they loose their head and their aggresive yikes.
He's mixed vs. pure bred?
BTW - keep him away from mules if ya like the clod.
