We have just discovered that Cocoa is actually only 9 months old, according to his Vet Records. He has made a great deal of progress since arriving here. He has accepted us as being the alpha's of our pack, and does not growl, snarl, or even put up a fight when ever we take away his bones. This is an extremely important milestone for him!
He has also learned to stay off the couches. He is not allowed in any of our rooms alone, this way he is under constant supervision. He still does not ask to be let outside, but he now responds to the verbal cues of "Outside?".
He still has some aggression issues with one of my dogs, but it is diminishing. I feel confident that it won't be long before learns everything he needs inorder to find his lifelong human companion.
