There is this relatively new product called “Adaptil” Calm Collar for dogs. Apparently, it is supposed to contain pheromones mimicking those from a mother dog to calm the puppy. The scientific name for the active ingredient is DAP or Dog Appeasing Pheromone.
Reviews on Amazon are quite mixed, there are as many 5 star reviews as 1 star reviews. I think this shows that dogs are complex creatures, it is unlikely that one product works universally for all dogs. Similarly, for humans, there is no single medicine that can “calm” a person down.
If you have any experience with Adaptil with your pet dog, for example how long it takes to show results, please comment below!
