The first command that you are supposed to teach is SIT. With a few minor differences, most dog training tips agree with each other. The easiest way to teach this command is, without much effort, to cause the desired result to happen. Hold their food bowl above and behind their heads for the very young puppies. Your puppy is looking up, losing his balance, and is sitting down. By saying the command, SIT, you strengthen, then praise the puppy and reward them with a treat. During each meal time and with treats, repeat this process until he is SIT on command without a food stimulus. Older dogs have better balance, so it may be necessary to take an additional step. In order to keep your dog still, some dog training techniques suggest using a leash without slack, then just using a treat held above and behind his head, command SIT. If your dog resists, apply pressure just in front of his hip bone with your forefinger and thumb or slide your hand over the rump and apply pressure as you tuck your legs and tail under to cause him to SIT. Every other fundamental command will build on the success of the SIT command, as always, praise and treat for the desired outcome. You can learn more at Spectrum Canine Dog Training.
The second command you have to train your dog with is NO. As the trainer, and every member of the household, this command requires consistency from you. In a sharp guttural tone and alone, the NO command always needs to be spoken. Do not use it with the name of your dog, or in a panicked or high-pitched tone that comes naturally only if you were to walk in and see your dog chewing your favourite pair of shoes. In order to relay your displeasure, your tone needs to be authoritative sharp and strong. As a punishment, withhold attention. Consistency is the key to getting your dog trained.
