Cocoa continues make progress. We can now take away any bones or toys from him at any time, so long as there are no other dogs around. He has accepted us as being dominant over him, but is still having issues around other dogs.
Cocoa is now walking quite well on a leash, so long as he is on a choker. He is no longer crying all night when we place him in the crate in the evenings, and willingly goes in when it's time.
We are now concentrating on his jumping, and his anti-social behavior towards other dogs.
