Hi Banger,
I don't mind what anyone calls me, as long as its not insulting :D Wow, has this thread really brought out some wierd debates.
Just to be clear, I said to check out the discipline measures of the training programs, just so you'd know in advance...not that you would ever do that to Max. :D
Not being famililar with dog clubs, I'm not sure of what type of obedience training you went through. I'm experienced with 8-10 week courses that meet once a week and then has nightly 15-30 minute homework assignments. Then there is a type of graduation and a second level can be attended. Nothing fancy, just basic groundings of behavior and expectations.
The reason I am stating this again, is that even you have said that Max is unpredictable. Well...to you, he is. To Max, well, he is just being Max. He has his own logic somewhere inside of him. There is consistency in his behavior. I've seen it from your numerous postings describing his actions.
When someone attends a lengthy class and works daily with a dog, eventually the owner/handler begins to see how the dog views the world and his surroundings. Each animal is different. One of my dogs will have her ears up when she figures something out. The other licks her chops when she realizes that she's doing what I want. I can see the gears in their minds work.
If you can anticipate a reaction, you can work on it before the situation gets worse. Stop it before it happens. That's your responsibility as a human because dogs just can't do this. Co-training lets both of you know what the other intends to do.
You live with Max...not all of these experts that you've seen and paid. You have to be the one to figure out what he is thinking and how he sees his world. Being told by experts after only a brief time, is only learning what they experienced, especially when he is completely removed from the household ...not how he interacts with you and your family.
I have noticed that you are extremely reactive and not proactive when it comes to Max's behavior. Because Max is not easy, you have to be the one to see where his actions are leading. For at least the next year, you cannot just relax and let things happen. It sounds as if he is your dog, so this is your responsibility...not your parents.
Have it set up that you can easily get ahold of him. NO more chasing through the room. I've had situations where the owner basically tied the leash to his belt and the dog went where he did. Sure, it was an inconvenience, but the dog didn't get into any more trouble with chewing and asserting itself with people. Within a month, he could be trusted off of the leash (within reason). Just as if you had a toddler, you always have to be the one to step in and take control of the situation.
For instance, your mother's feet. The first time he bothered her and she did not want him to, he should have been removed from the situtaion (down/stay, ejected from the room, ---something)...not let it happen for a half hour, that's for certain.
If he growls at something, don't react uselessly. Do something to change the situation and let him realize that he is not in charge .... such as dominant/down, lying down, ejection, or if you're on a path, turn him around and run him through basic obedience commands. Hitting, yelling, snapping newspapers, panicking, bellowing ignored commands will not end this problem. (oh, and don't use extend-leashes with him for a very long time--the handle just does not allow good control)
Seriously, if Max continues to be unpredictable in your mind, eventually he will become another tragic statistic. You have to figure what works for you and Max out on your own. {German Grandaddy's favorite saying : You have to be smarter than the dog to train it} We can only offer suggestions.
Using his lineage as a possible reason for his behavior is basically a waste of time. There is nothing you can do about that, even if you determine his Dam had a screw loose. There has always been the argument of Nature vs. Nurture. I view them as a blend, just like you cannot describe an acre using only width and leaving out length.
It sounds as if Max has had enough incidents happening to him while he was young to enhance his sensitivity. Purebred or mutt, dogs are dogs. The highest champion would still throw and rub himself happily upon carrion. Ick :(
Of course, this is all just my humble opinion :rolleyes:
Happy Easter
