Flor Du Rocher Des Jastres (Prop. Obrist, Prod. Comte) pedigree obtained her blood tacking certificate. For this certificate, the dog must follow a scent put 24 hours before, the dog must stay on the tack and reach the goal! At least 3 angles to take. Obedience is come here, sit, lay down, come back, gun shot... then lay down during 10 minutes, without the handler, gun shot ... the dog must not make any noise, not leave its place! Then remain a quizz for the handler, law, dog science.
