Bananas are a natural beta blocker having a similar affect to a (pharmaceutical) drug class called beta-adrenergic blockers. Beta blockers are prescribed to treat anxiety, reduce blood pressure, or heart conditions. Beta blockers prevent adrenaline from binding to beta receptors which results in lower blood pressure and pulse rate, which normally skyrocket when experiencing anxiety and under stress and bananas have been shown to result similarly. Bananas are high in potassium, an essential mineral which causes a boost to the excretion of sodium resulting in decreased blood volume and reduced blood pressure. A boost in potassium levels is beneficial for anxiety because when your pooch is under stress their metabolic rate rises and causes a drop in potassium levels. Bananas also contain tryptophan, a protein which can be converted into serotonin. They also contain a high amount of B vitamins which can aid in calming the nervous system.
To get optimal results from these rewards, we recommend feeding them half an hour before the event/anxious situation.
