Dogs react to food.
Give small treats to reinforce good behavior as you teach a dog tricks.
As they learn, take away the treats a little at a time until they are obeying commands without food.
Repeat the action. Repetition is key when you teach a dog tricks.
They need consistency to understand what action they are being asked to perform,
and repeating the action solidifies the learned behavior.
Work with the dog every day. Training has to be done on a regular basis in order for the information to stick with the dog.
Taking time every day will ensure that the tricks that have been learned in the past will continue.

Keep training sessions short 3-5 minutes is plenty

Do not say the verbal cue until your dog is doing the behavior.

Do many short training sessions per day.

Train old behaviors like new behaviors in new places, around new people, or in the presence of other animals.

Act as if your dog has not learned the behavior, and start at the beginning, until he has generalized the cue.

Smile at your dog while training. Speak in cheerful tones.

Do not chat with your dog while training him, it confuses him as to what word he should be listening to.

Do not repeat cues, if your dog is not responding to a verbal cue change something you are doing or make adjustments to the training environment.
