practice with her in the garden or out for short walks and when she pulls do a left circle and then walk straight and if she pulls again do a right circle and then walk straight.

shes getting into the naughty stage but I think I was told that terriers reach adulthood at 12m and miss out the teenager bit I'm sure someone will correct me if I'm wrong!!!!
