I got a problem

......Cute and pretty as he is, this almost 7 month old is becoming territorial. And I'm finding myself not trusting him at times that I need to handle him. He's starting to make contact with my body parts

, if I have to get something out of his mouth he SHOULD'NT have, or moving him out of an unsafe or bad, or comfy situation, and a rather large area he claims when it's meal time

. He's rather serious about all this too, and I try to scold him and shake him silly by his collar, but it's not getting through to him. I can feel he knows he is scaring me too

. How can I get on top of this.....and HIM?????
