A natural sleep settling product-much better than pharma products.
I have used this product with multiple super senior doggie's with sleep settling issues. It's been fantastic over the year's and is not dangerous to your doggie's health at all.

Great product that works .
Continues to work amazing for our dog with CDA . It has been a staple in his diet for 3 years now . On the higher end of the spectrum for price but works amazing . Dog doesn’t seem to have any taste issues . Chewable for sure . No known side affects with our dog . Doesn’t calm our dog because he is a wild man always .

Very good product
Very good supplement. My dog, who tends to lose spots of hair in the winter, no longer has that problem when taking K9 Melatonin daily. He is also somewhat less anxious, which is a bonus. Will definitely buy again.
