While I understand that family’s schedules are often difficult to align, it is helpful to have as many people as possible present. This provides greater consistency with your pup leading to a greater success rate in achieving your goals. A lack of consistency can provide confusion. That being said, those attending should be age appropriate. I find that young children provide more of a distraction and cause difficulty in the parent’s ability to concentrate during training. It is helpful to provide your child with an activity or game during this time to allow you to stay focused!
