he is anxious little flower ... had him on valerian root twice a day for a while .. only took the edge off slightly .. he gets testy with his siblings when all of them are barking .. even with much calm leadership and good walks he is tense .so .. we added a cbd treat at bedtime on top of the twice a day valerian root .. this has helped greatly .. improved our bossy little anxious boy ... now the three bros get on with less reactivness from kevin.. doug and gary appreciate it greatly
