The lack thereof, the missing info that was posted and debated in this thread (on the wrong dog) was suited for that thread and that OP or her dog may very well be in trouble. I could only imagine what would happen to the dog if she continues to allow that dog in the bed, on the couch and plays tug with it. She is obviously an inexperienced CC owner and this is in no way meant as disrespect as we all once were none CC owners. If the current ways continue the dog will be out of control at 7 or 8 months and the aggressive biting becomes serious.
I could only imagine how many of these dogs could have been saved by not getting into first dog owner households or from going to Petco style obedience classes. 7 to 12 months seems to be a turning point at the CC rescue centers and by then the imprinting is so bad it makes it much harder to turn around.
