He is about 3-4 months old. We have started some very basics with him. I do need to get him out on a leash. Will be getting him his own leash tomorrow. I am excited about that for him. I just know very little about the breed other then prejudiced opinions similiar to many of the other 'protection/working/police' breeds. I had read there can be a problem with male/male dog aggression with the dobes. He will be neutered in a couple of months so that should help there. Wondering if there is any other positives or negatives I should know about this breed.
