Get your family involved in training your dog. With that, even if they won’t take parts during the training sessions, you should let them become more familiar of the commands that you use.
Aside from using the same commands, all the members of the household should also handle and train the dog the same way, so as to practice consistency
Train your dog in accordance to what is acceptable in your house
If you don’t want certain things for your dog to do inside the house, then you should train him not to do it.
For example, if you do not want him to treat your sofa as his bed when he grows up, then you should not encourage that behavior.
Do not let him climb the sofa regularly, so that he won’t consider it as his place to relax.
If you want to cuddle him, just sit on the floor, or put him on your lap.
