Our six month old Chessie is very aggressive with his food. He's okay with biscuits and small treats, but once he gets involved with his meal time. I've limited him to hand feeding only - and he still snarls and nips at me when he's waiting for his next handful of food. He seems very anxious, nervous, and afraid. I do not yell at him when he snarls, I just remove the food and distract him. At the end of mealtime, he remains in that emotional state for a few minutes and eventually calms down. We did have him neutered a week ago and expect him to calm down slightly in another week or so, but that's no guarantee.
Should I be doing anything more? Should I stop doing anything?
