From the makers of K9 Choice Brand Melatonin: introducing our new K9 Select Beef Flavored Chewable Melatonin. Each bottle contains (120) 3 mg chewable tablets in a beef liver flavor that dogs love. Melatonin is reported to be an immune system booster. Melatonin also inhibits two enzymes needed in the production of Cortisol (a stress Hormone), thereby effectively reducing excess Cortisol levels. Melatonin is a well known antioxidant and when used in conjunction with Lignans, it works to manage the symptoms of ailments associated with heightened Cortisol levels by lowering the amount of Cortisol in the body. To reduce cortisol in dogs: veterinarians recommend giving 3 mg of melatonin every 12 hours for dogs under 30 lbs and 6 mg of melatonin every 12 hours for dogs over 30 lbs. For separation anxiety, fireworks, stressful events, or sleep, give 1 tablet about 1 hour before the event.
