If you are crate training your dog, you need to show them that this is where they will sleep. You should put their food in the crate when they eat, but leave the door open. They'll build a positive view of the crate this way.
Get your dog the proper nutrition required for canine health. A bad diet can cause your dog many problems.

A proper diet can affect how well they react to training.
It is a simple task to teach a dog how to roll over, just be sure to keep some dog treats handy! The first step is a simple “lay” command. Hold a treat between your forefingers near the left side of your dog's head, and then slowly pass the treat in front of his face and to the opposite side. He will follow the treat by rolling over. Whenever your dog does actually roll over, say “roll over” out loud. Repeating this over time forms a mental association in your dog's mind that eventually causes him to roll over on command. Have patience since your dog may not get the trick quickly. However, once he does, he'll be the center of attention at the dog park.
Stay away from high end training devices like shock collars. They often do not function well as they say they do and are a lot more expensive as opposed to conventional methods of training. Plus, shock collars can discourage your dog from behaving properly. Usually if you do this your dog will respond in the wrong way.
Approach an unfamiliar dog slowly, offering only the backside of your hand for his inspection. This lets them warm up to the scent and they'll most likely trust you. Once a dog is used to your scent, it will trust you and obey your orders.
Now that you have been provided with this useful information, you are on your way to having a well behaved dog. Knowing the proper training techniques is the only way to train your dog properly.
