I am trying to extend their "level of frustration" by doing Tot (triangle of temptation) with 11 month Marley and 18 month Schubert.
When Schubert is not there, she will not even go near the food.
She is waiting for Schubert to return.
Anything I can do?
... or should I just not worry?
Tot means, they were separated for eating, but they always knew the other was close.
I do separate them for training sessions, or they go for walks individually.
but most of the day: they spend together.
