Why don't you train her to "here", then Ecollar condition her? Then you would know she would always come. I always have Ecollars on mine when we're out, that's my ace in the hole.
Thanks for the information. I would love for her to run wild and free when her safety is not in jeopardy.
When I take my waterdog to the nearby lake he’s always on an electronic collar. I can’t trust him 100%, but he always responds to the ‘tone’. He knows that means “drop everything & return to front.” Save him from getting into it with other people trying to enjoy the lake (fishermen especially).
