When using a crate, make sure that it is large enough to let your pup stand, turn around, and lie down comfortably. However, it should not be so large that your puppy could use a corner of the crate as an elimination spot. If your dog does start eliminating in the crate, you should stop using this method. Your puppy may have picked up this bad habit in a previous home, or he may be too young to deal with a crate.
Step 1: Using either a laser pointer or touch stick, get your dog in the habit of jumping up to touch the light switch. It is best to have him jump up with his pads on the wall (instead of his claws) touching the switch with his nose. I used a laser pointer here, because I would play with it as a game, knowing that he would really go after it—even if it's on a wall.

Dominance is a descriptive term for the relationship between pairs of individuals. Among ethologists, dominance has been defined as "an attribute of the pattern of repeated, antagonistic interactions between two individuals, characterized by a consistent outcome in favor of the same dyad member and a default yielding response of its opponent rather than escalation. The status of the consistent winner is dominant and that of the loser subordinate."[33] Another definition is that a dominant animal has "priority of access to resources".[33] Dominance is a relative attribute, not absolute; there is no reason to assume that a high-ranking individual in one group would also become high ranking if moved to another. Nor is there any good evidence that "dominance" is a lifelong character trait. Competitive behavior characterized by confident (e.g. growl, inhibited bite, stand over, stare at, chase, bark at) and submissive (e.g. crouch, avoid, displacement lick/yawn, run away) patterns exchanged.[34]
It is a common misconception that winning and losing games such as "tug-of-war" and "rough-and-tumble" can influence a dog's dominance relationship with humans. Rather, the way in which dogs play indicates their temperament and relationship with their owner. Dogs that play rough-and-tumble are more amenable and show lower separation anxiety than dogs which play other types of games, and dogs playing tug-of-war and "fetch" are more confident. Dogs which start the majority of games are less amenable and more likely to be aggressive.[14]
If you run into trouble, go back a few steps If you’re training your dog to do something new and you stop making progress, you may have increased the difficulty of the skill too quickly. Similarly, if you’re practicing a behavior your dog hasn’t performed in a while and she seems a little rusty, she may need some help remembering what you want her to do. If you run into training challenges like these, just refresh your dog’s memory by making the skill a little easier for a few repetitions. Go back to a step that you know your dog can successfully perform, and practice that for a while before trying to increase difficulty again.
My husband and I used Amazon Basics brand Puppy Pads while potty training our puppy. They are much cheaper than the name brand pads and we found that they actually seem to hold significantly more liquid too. This made our clean up job after work much easier since all we had to do was dispose of the pad (and not have to clean the tile floor beneath it).
Scent. There are several scents that are displeasing to your dog and emitting those smells into the air near his face will go a long way to deterring him from bad behaviors. The smells are typically citronella or mint so keep in mind that if you’re also not a fan, the smell may just bother you a bit, too. This isn’t the most common collar and it can be hard to find, but if your dog is particularly sensitive to smells, this may be the best bet for you.
Dog behavior is the internally coordinated responses of individuals or groups of domestic dogs to internal and external stimuli.[1] It has been shaped by millennia of contact with humans and their lifestyles. As a result of this physical and social evolution, dogs, more than any other species, have acquired the ability to understand and communicate with humans, and they are uniquely attuned in these fellow mammals.[2] Behavioral scientists have uncovered a wide range of social-cognitive abilities in the domestic dog. dog training collar
Some people believe that the only way to transform a disobedient dog into a well-behaved one is to dominate her and show her who’s boss. However, the “alpha dog” concept in dog training is based more on myth than on animal science. More importantly, it leads misguided pet parents to use training techniques that aren’t safe, like the “alpha roll.” Dogs who are forcibly rolled onto their backs and held down can become frightened and confused, and they’re sometimes driven to bite in self defense.
You may also notice common behavior problems in your dog such as jumping up, barking, or even aggression. The best way to correct any misbehavior is to interrupt it. Shift your dog's attention to something positive. Try running through cues that your dog has mastered followed by rewards. Keep your demeanor cool and confident, and be clear about what you mean. 

Stop them from barking. Excessive barking can be frustrating, especially if the neighbours are threatening to put in a noise complaint. Using a training collar can help to get rid of this habit, as it will activate as soon as barking is detected. For the citronella spray, the release will surprise them into silence, and the release of the odour will be associated with barking. For sound and vibration, it is much the same in that it startles your dog, and the more they bark the long the sound and vibration go on for.  

A training class is not there to train your dog. Its purpose is to teach you to train your dog so you will need to be committed to train your dog for short sessions (5 minutes) several times a day rather than just simply turn up for classes! This little bit of training everyday will be repaid with a lifetime of living with a well behaved dog. You will also learn to avoid problems before they begin as well as receive help to overcome any that you already have with your dog. go here for more
