Small dog training isn't much different from training other sized dogs other than the fact that they are small.
When training them commands like sit, stay, heel and so on, it is important to have a direct done with them.
Not to yell or make a tone they should fear, just a tone that is dominant.
When doing small dog training, be sure to be patient with them.
All dogs have different personalities; get to know your puppy for who he is.
Working with your puppy and how they are personality wise will get your training through a lot quicker.
Dogs have emotions too and you need to understand them when you are training.
Small dog training can be easier than training a larger puppy as the larger puppy is harder to keep control of when in the training phase.
Consistent training with any dog is the way to ensuring ample training progress.
Always stick to the same commands for actions that you want your puppy to perform.
Train the puppy by one person, multiple people attempting to train the puppy at once will only cause confusion.
If you are doing small dog training on a hyperactive kind of dog, it can be a bit more difficult.
Calming them down before training by taking them for a walk can help.
Make sure when you feed your puppy that they are fed at different times than the family is eating.
Feed the dog in an area that is out of sight of the dinner table.
Keep in mind that small dog training is almost the same as training any other puppy.
It comes down to commands, being patient and being persistent with them.
Follow through with daily training with the puppy, and follow it up with play time after the training.
In the end you will have a well trained dog.
