It's important with all dog training but especially with young puppies to use lots of encouragement, praise and rewards (positive reinforcement) in your training. Start your puppy training sessions as soon as your little puppy arrives at your home - it's never too early. Set your puppy up to succeed, concentrate on developing desirable habits in your puppy and preventing undesirable behavior. It's much a better alternative to put your puppy on the right path from the start, rather than trying to correct established problem behaviors later on.
Remember that training is an ongoing process. You will never be completely finished. It is important to keep working on obedience training throughout the life of your dog. People who learn a language at a young age but stop speaking that language may forget much of it as they grow older. The same goes for your dog: use it or lose it. Running through even the most basic tricks and commands will help them stay fresh in your dog's mind. Plus, it's a great way to spend time with your dog.

Aim to develop a behavior in our dog that reflects the harmonious partnership you both share. He should have enough confidence in himself and in your leadership. This way, he can be confident in situations, such as being left alone, because he knows that you will always provide the leadership and guidance required. He trusts and knows that you will come home.

You can start your puppy off on the right paw by teaching good manners from the moment you bring him home. Every interaction that you have with your puppy is a learning opportunity, and with gentle guidance, you can help him understand important lessons like how to greet new friends without jumping up, how to wait quietly for dinner and what to do with those puppy teeth. 

If your dog is nervous because of situations like fireworks, thunderstorms, or even being in a crowd, then distraction may be your best option. By working your dog's brain you will help him focus on you and things he knows, rather than on the unknown around him that's frightening him. While it isn't the time to begin new training, it is a great time to practice tricks your dog knows and can earn rewards for. Try rewarding your dog with treats for simple commands like sit, stand, lie down, shake, sit up, roll over and other tricks he enjoys

One thing that is very important with desensitization exercises is that during the retraining process, it is important not to expose our dog to large doses of the fear stimulus. The key with desensitization is to start small, and only very slowly increase the strength of the stimulus. In this way, our dog is able to stay calm, learn from the experience, and can slowly rebuild confidence.

You can teach your puppy at home and I'll help you. My puppy training book is called Respect Training for Puppies: 30 Seconds to a Calm, Polite, Well-Behaved Puppy. I'll show you my proven step-by-step training schedule for teaching your puppy all the words he needs to know, plus consistent household rules and routines, housebreaking, crate training, acceptance of being handled, calmness, gentleness, and general obedience training.

My unique method of balanced dog training brings peace and harmony into the lives of committed clients and their families, who understand that real change is possible when the right approach to their dog's behavior is consistently applied and practiced.  My programs serve to bridge the gap between human and dog communication, by helping you and your dog improve your relationship and bring peace into your life!  I can relate to many of my clients, because I too used to struggle with my dogs and tried many different training methods that were not effective for us.  I am so fortunate that I am able to help my clients - especially those who have tried other training already - find a successful program that gives them consistency, peace of mind, predictability, and a lifestyle that they can enjoy with their dog and family.
Also, I have not been able to find any truly convincing studies on the Thundershirt. The only ones I could find were sponsored by the Thundershirt company. This one looks somewhat interesting and talks about a hide-box and measuring cortisol levels and heart rate, but I was not able to find the actual Journal publication that they alluded to in the article.
Your dog must finish our Basic Obedience Package before we will teach them advanced lessons! We offer numerous advanced lessons! Some are: extended distance obedience (your dog will be sitting/downing on command from 50+ yards away from you), heel command (they come running, go around you and sit down right beside your left leg), watch command (stare at you until you release them), through command (go in between your legs and sit down), stand command (they will assume a standing position on command), front command (they will come running and sit directly in front of you no matter where they are), focused heeling (will stare at you the entire time they heel), touch command (they will run up and stand up against anything you point to), and many more!
^{Puppies can begin very simple training starting as soon as they come home, usually around 8 weeks old. Always keep training sessions brief — just 5 to 10 minutes —and always end on a positive note. If your puppy is having trouble learning a new behavior, end the session by reviewing something he already knows and give him plenty of praise and a big reward for his success. If your puppy gets bored or frustrated, it will ultimately be counterproductive to learning.}

Thank you both for the reply. We had noticed the beginnings of arthritis about a year ago, and our vet recommended we put her on a glucosamine regimen. Although I’m sure she experiences some level of discomfort from the arthritis, it hasn’t seemed to stop her from running outside or playing frisbee. She does seem to be experiencing some cognitive confusion, which may well be a result of her diminishing senses. She is better today, in terms of the panting and trembling…but she has still chosen to isolate herself in a corner bathroom, and is sleeping most of the day. But, she is calmer than is previous days. She does have a Vet appointment soon, so we will raise your suggestions then. Like with Lady, I just have been unprepared to seriously consider my life without her…but I would never want to subject her to misery, if it seems she has no quality of life. Again, thank you both for the reply.

No biting is more of an action taken to discourage puppy biting than it is an actual obedience training command. Puppies have a habit of biting anything and everything and this behavior should be discouraged from the beginning. Discouraging biting can be done with a variety of ways. One of the most used methods of discouraging biting is to firmly say “no” and replace the hand or fingers that are being bitten with a toy that it is acceptable to bite.
