Great advice thus far. Why not crate the dog during the night so he's not dashing into places he shouldn't be? That'll make sure he doesn't jump up on the bed. If you don't want to crate him, you can set up a baby gate either keeping him in a room or keeping him out of your bedroom. Either way, it'll ensure he doesn't water your bed.

Furniture should be off limits except by invitation only and at that time the dog had better have a solid understanding of the "off" command. For now though, I would just drop all lap/furniture privileges. If you want to have him on your lap, sit on the floor and call him to you. From now on, he should lose all furniture privileges. If he gets up, you put him back down. If he insists on jumping back up after several attempts of putting him down, crate him for a bit and let him chill.

Have him on leash when people come over so you have a means of control. Instruct anyone coming into your house to IGNORE your dog. Don't say hi to him, don't reach down to pet him, don't even acknowledge his existence, just have your guests greet you and the other people in your household first. Your cockapoo may try to jump up but if people ignore him, eventually he'll settle down. Still keep him on leash so you can control his movements. When he's settled, you can have people meet your dog, but still keep him on leash. If he tries to jump up, reel him back in.

I don't really see the need for a prong collar at this point as it's not necessarily him being disobedient, just him not having a clue what's expected of him. I do think you can increase his obedience (train him to sit, down, come, stand, etc and work on it in different rooms and outdoors) and his exercise. A tired dog/pup is a good dog/pup. That'll help get rid of the nervous energy. Obedience should happen all the time. If you want to pet him, have him sit or down. If you want to feed him, have him hold a down and wait for a few seconds. Before going on a walk, have him sit at the door. During the walk, teach him to plant his butt on the concrete every single time you stop. Bring some tiny treats with you and teach him to focus on your face while walking and spit the treats out of your mouth so he learns that keeping an eye on you is fantastic. There are many ways to incorporate obedience training throughout the day.

Because leadership is so important, here's an excellent reference link to various leadership sources including the groundwork article from this site: http://www.germanshepherds.com/ubbthreads/showflat.php?Cat=0&Number=640483&an=0&page=0#640483

I definitely recommend Jan Fennell's book, "The Dog Listener." Excellent ways of gaining leadership through lifestyle changes.

Amy,
Well first off there is always hope. My biggest question which no one else have raised thus far is how much exercise do you give your pup on a daily basis. Some of this sounds like pent up energy and the word on this board is a tired dog is a happy and content dog. So the first thing I would do is give your pup more exercise on a daily basis. That would be number one on my list. At this age a good walk for about 15 mintues to a half an hour twice a day would more than likely be okay. That is a exercise walk and not a stop at every bush type of walk, just so I am clear on what a walk is. Number two is that I would not use a prong collar or anything else until you are 100 percent sure that your pup knows what you are wanting him/her to do, correcting a pup for not knowing what to do or is expected is not fair in my book at least. So first off back way up to the very basics, make all of that a positive and rewarding experience for your pup, reward, reward and then reward some more for the things you want to see in your pup. Corrections are more than fine in my book once I am 100 percent certain my dog/pup knows what I want from them and they are chosing not to do it.
Exercise
Train be consisitant here.

So back way up to the beginning, it will go much faster this time around, work on this EVERY Day. You can not blame your pup for your lack of training with him, do not get mad that is what you have kind of said yourself. So train every day, no distractions until you are ready to proff. Then the distraction will have some value. At 6 months I would not expect this pup to act like an adult dog, meaning that he/she will have a very hard time with distractions for sure. When they get older the distractions will not be as bad, but the attention span this pup will have is nothing like an adult will. So back up, slow down and expect from your pup what you are putting into them on a daily basis. Training at this age is very short and sweet, like 5 minutes at a time max. Also I would train only one thing at a time, like the sit, I would not have them both sit and down in the same session. After you work on both of them and are sure that you are sure that you are sure that they know thse diffence then work them both in a single training session, just not in the beginning.
Yes ED's DVD will help and answer many of your questions for sure. Sounds like your pup is very submissive so we do not need to go down the road of pack and rank order.
I always try and remind myself that my pup is a pup and ask myself what would I expect from a child of the same age, in most cases my answer is NOT MUCH... LOL A pup at 6 months is like a child at 6 months only they can run and play and get themselves into much more trouble.

PS. My dog is not allowed on any furniture in my house but then again I have a GSD and he is much bigger than your dog is.

How often is your pup exercised during the day? I didn't see you mention anything about that in your first post.

To me, exercise is a key role in obedience training with a dog. Sounds like the pup has got the jitters and is trying to work off some excessive energy.

If you are already walking him, maybe you're just not wearing him out enough.

Although obedience training can work too at tiring out a puppy, sometimes you will have better luck with the obedience training once you have let the little guy work off some of his energy first. That way he'll be more apt to pay attention to you and not be bouncing off the walls.

As for the jumping on guests & peeing. Are your guests petting and making a fuss of the dog when they come in? If they are, that part has to stop. Ignoring the dog when they come in is a good start at teaching him what is acceptable as far as greeting guests goes. Plus I found the the urination part (excitement peeing, not submissive peeing) is due mainly to excitement and if you ignore the little guy for a bit and let him settle down before you pet him, it usually helps.

I'm suddenly feeling very good about my dog

Several people have advised you to put a long line on him. In the house, my dog is on a 6' line. For us, that's long enough that we are able to get control of him if we need to, and short enough that it doesn't get wrapped around table legs and chairs.

Also, you don't say if you use a crate. If you don't, get one. If you do, don't be afraid to put the dog in the crate when you can't have eyes on him or give him close attention. When we have people over, if we even suspect our dog will be a nuisance to them, we crate him. See http://leerburg.com/housebrk.htm it's about housebreaking, but goes into detail about crate training.

My dog was a submissive urinator until he was about 9 months old (he's 11 1/2 months old now). We learned to let him meet new people outside. He would often urinate when my wife came home from work, so when she'd get home we'd take him outside to greet her.

I swear by the prong, and we put our dog on one when he was quite young. Hard pulling and fighting, and other disciplinary issues became non-issues or easily corrected by the prong. I think your guide should be that if he becomes easier to control with a line on a prong than with a line on a flat collar, then use the prong.

Good luck!

Amy, everyone has already been giving you excellent advice on this thread, but I'll just reiterate a few main points...

A. Order "Your Puppy 8 Weeks to 8 Months" (it's NOT too late!)
http://www.leerburg.com/120.htm

B. Get a nice crate, have Pup sleep in it & confine him there when things are too hectic for you to cope with the dog.

C. Don't let him run WILD around the house getting into trouble -- The minute you take him out of his crate, snap a leash on the dog, take him directly outdoors to relieve himself, and then keep him tethered indoors when he's not crated.

D. Follow Ed's advice in his "puppy groundwork" ARTICLE daily (there IS light at the end of the tunnel!)
http://www.leerburg.com/puppygroundwork.htm
And I would leave the Basic Obedience training for afterwards...

E. Force yourself to stay calm & quiet when interacting with Pup.

I'm sure this "out of control ca-ca-pooh" (sorry, couldn't help it) is a pretty smart little cuss & his training WILL go well, once you establish yourself as a leader & put a sensible routine in place for him <:-)

Good catch.

Structured daily exercise: always number 1, and I am embarrassed not to have said so.

Thanks to everybody. These are all great posts. It's funny, I read this forum almost on a daily basis and I've read all of this advice before but I guess I just needed it said directly to me to light a fire.
I really feel like I know what to do now.

Exercise, Exercise, Exercise
Fun SHORT obedience work nightly
Attach a long line
And STAY CALM!!! (among many other things)

Thanks again to everybody. Time for a fresh start.

And I do crate him at night and during the day while I'm at work. I always try to keep him out of the crate during the evenings b/c he's crated all night and 7-4 during the day (aside from my lunch hour). But if I stay consistent with the exercise then crating him part of some evenings shouldn't be a big deal.
Thanks to all.
