Dog Owners always ask, it is possible to send your puppy to some Board and Training Facility, and they will be returned to my trained dog. The Answers is Yes and No.
Let me give you an analogy. Dog Training is like driving a car. Once you learnt how to drive, your skills depend on daily practice. For example, if you took 2-weeks of holidays and you will return home and start driving, your driving skills, road sense, parking, changing lanes need some time to be back to normal.
It's the same as dog training. If you don't practice the skill sets regularly, your puppy or dog will not be capable of performing the behaviour you are requesting.
So it will be like you will need a driver to ferry you around, as you are not capable of driving. And you still can't manage and handle the car.
