Promote your pup’s relaxation, calm, and comfort with K9 Select Melatonin Peanut Butter Flavor Calming Dog Supplement. This delicious, peanut butter-flavored supplement features melatonin to support your pal’s overall health. Each chewable tablet works to promote normal thirst and urination as well as skin and coat health. But most importantly, it acts as a natural signal that it’s time to sleep. As your dog ages, their natural melatonin production may slow. K9 Select Melatonin provides natural support for your pup’s sleep-wake cycle, helping them stay relaxed and enjoy more restful sleep.
