Hi has anyone used skullcap & valerian? Our obedience class leader suggested using this every day as Molly is 9 months old now & her concentration has gone!! Her already bad re-call has gone & when you tell her to leave something she doens't listen. We have been giving her Dorwest skullcap & valerian 8 tabs per day for the last 3 weeks and haven't seen any difference..anyone had any success,is it safe to give Molly that amount everyday???
