can melatonin be given to dogs
âMelatonin â¦ can be dosed at 1.5 mg per dose for dogs under 30 pounds, and 3 mg per dose for dogs over 30 pounds. Repeat, if needed, 2-3 times a day. I would not recommend continuous dosing for weeks at a time, but during a stormy day or two, you can do it for the duration.
