Quick answer: Calming collars are sold to reduce anxiety in dogs. Some contain a synthetic version of a dog appeasing pheromone, while many inexpensive multipacks rely on herbal or essential oil scents. Evidence for pheromone products is mixed, with some studies showing modest benefits, and there’s little evidence for scented herbal collars. They may help some dogs a little, but they aren’t a substitute for behavior training and, when needed, medication from your vet.
