These Really Work!
My Cavapoo is 9 lbs and a year and an half. Nothing settles her down. I sometimes have to give her 2 for her to be able to go to sleep. She doesn't get sick off of these but digests them well. No diarrhea. She just naturally falls asleep about an hour after I give her one. If she doesn't settle that is when I give her another one and that will work. Highly recommend!

My Lab now gets a great night sleep!
I have an older Lab dog that has troubles sleeping at night....he would get up and start wandering around the house several times during the night. He would get confused and go from room to room and I felt so badly for him. I then bought K9 Select Melatonin and it worked the very first night! He now sleeps through the night, wakes up refreshed every morning with his tail wagging!!! I wished I would have found this great product earlier for my sweet old lab!!!

Works a little too well
Worked super well for our 11 month old puppy, 60lbs. She has been having trouble sleeping through the night and one pill had her very drowsy for over 24 hours. Did experience drooling, which isn’t normal for her, but nothing too concerning.

Safe and effective with no side effects!
I have used this product for some years now and found it very safe and effective. Especially around the holidays when fireworks are being set off. Also when my dogs are going on a trip etc. I use both 3 and the 6 mg bottles. I have a German Shepherd and a Rottweiler who have been on these K9 Select Melatonin for years. They are to safter to me than prescribed "Chill out" meds from the vets office. With no side effects I might add.

Calmer less stressed dog
Excellent results for our senior dog with possible cognitive disorder, wish we had known sooner. It as calmed her and helped her sleep better during the night. I would recommend it.

Didn’t Knock Him Out—Just Calmed Him
I have an 11 year old Olde English bulldog. He’s been getting up frequently at night and started pacing. I gave him one of these for about 2 weeks nightly and didn’t notice much difference. I will say he maybe was calmer at night, but he didn’t fall asleep any faster or sleep longer.

It appears to be working
My Take on K9 Select Melatonin Chews for Dogs My 11-year-old pup's been having rough nights—pacing, whining through storms, and just not settling like she used to. I started her on these 6mg beef-flavored chews yesterday (half a tablet twice a day, as recommended for her size), and fingers crossed, but the early signs are promising. The natural melatonin angle feels right; it's vet-backed for regulating that sleep-wake cycle, and the calming boost could help with her anxiety during fireworks or thunder. She gobbles them up—no forcing pills down her throat—and the nutrient-rich formula might even perk up her coat, which has been a bit dull lately. Too soon for a full verdict (it's only day two), but no tummy upset so far, and she seemed a tad more chill last evening. If it eases her stress and gets us both better sleep, it'll be a win for this senior girl. Verdict: 4/5 (tentative—holding out for week-one magic). Worth trying for anxious older dogs; I'll update if it sticks.
