I'm not exactly sure how to handle this.....but, Taco, who is 10 months old, neutered at 8 months), has recently started getting aggressive and growling, trying to maybre snap when I try to take something away from him (like all those things he thinks he needs to chew on or eat that he shouldn't (he did it when I tried to take a leaf away from him outside). This is a REAL growl, not a play growl. I really don't like this aggressive behavior. So far, the only thing that I have done is, take the item away, tell him "No, No, you're a BAD DOG and ignore him w/ no eye contact for a while. Is this the best way to handle this or should I do something else. HELP.....I don't like this behavior.
