I am enjoying some success on the dog training front. I'm not quite sure how I've achieved this but approximately 7.5 times out of ten, my little black bunny killer now responds to the command: 'Biff, come here, NOW!'
The crucial word is 'NOW' which has to be shouted at 100 decibels and delivered in a fearsome fashion, shattering the peace of the surrounding countryside as far away as Angouleme. Not so much the dog whisperer as the dog shrieker.
I can personally vouch for this having witnessed it first hand. It works well - although ear defenders should be offered to friends who accompany you on these walks. best S.
