They did get the Jack Russel to focus and they could do short training session it was very food motivated. Yuo might try a few very small high value treats like cut up chicken hot dogs or something then just don't give in until she sits still. The moment she is still, praise and treat. Repeat and repeat and repeat. However as soon as the training session is over she will be back on like a ball of fire.
