I have a Senior chihuahua that has a neurological disorder and takes 2 medications to manage seizures and tail chasing. I've paired this Melatonin supplement with those medications to help him relax at night and it has helped immensely. He relaxes easily, sleeps through the night, and his spinning behavior does seem to tone down in the evening once he has a full dropper of this. Would suggest for people who just need a little extra help calming their pups in the evening.

Works wonders

Really helped my dog relax before bed. Just make sure to check w others in the house that they haven’t already added it to the water bowl!

I tried this on my almost 17 year old dog with dementia, to help with his nighttime pacing and barking. While it did help him calm down overnight, it also gave him horrible and persistent diarrhea and after taking it for two nights, his stomach was so upset that he stopped eating.

I’ve tried many supplements as well as prescription drugs from my vet but they all either didn’t have any effect or made him seem on edge. I’ve only tried one dose of this but the difference is remarkable. I hope it continues.

Cat seemed a bit calmer and is less likely to pull out fur.

She doesn't like being dosed but it helps.

This is the best thing for doggies who suffer from anxiety and can’t deal with to many little humans and loud sounds

This has helped our recently adopted Chihuahua that becomes more alert and anxious at night to wind down and sleep through the night. He is about 8-9lbs and we give 3/4 a dropper. He is a picky eater, but we drop it on freeze-dried treats so it soaks in and he eats those happily!
