“Phaze is 7 year old Border Collie that competes in the sport of Dog Agility I know her pretty well, and the effects which I have observed since adding Nupafeed Stamina-Extra to her diet. Recovery times from competition and training even her normal walks has vastly improved! Muscle mechanics surely has improved as bar knocking is far less and muscle growth improved by gaining nearly a kilo without excess body weight! Stiffness and fatigue to muscles after a run seems to be considerably less from before, as she’s a lot more mobile say 30 minutes post run. And most importantly her concentration and decision making on course in competition has been exceptional having greater success this year. Very happy with the results thus far!”
