well, she wasn't actually ferreting, just watching, best way to learn IMO, she learnt to sit and wait and watch, just what parker does before he catches
If you look on the pic of me crouched with her you can see she is on a lead, so not running around chasing anything, plus we werent putting nets up and down, so it was only 2hours we were out for. agree if she was walking for that long it would be too much for a 3month pup, but she just learnt to watch and be quiet. all valuable skills. we took parker out as soon as he had had his jabs and is brilliant ferreting.
