Jack Russell Terrier is a real perpetual motion machine. He is simply physically unable to sit in one place for a long time and get bored while waiting for the game. This dog will attract the attention of the owner in all possible ways. She perfectly knows the rules of conduct in the house and can deliberately violate them in order to cause at least some reaction from the owner, who is too carried away by her favorite TV series or new book.
It is important to remember the high intelligence of the pet. Physical activity must necessarily be accompanied by mental activity, otherwise, any activity will quickly get bored. Alternate commands and toys, come up with new activities.
