If there is a risk of a stressful situation, sometimes even unannounced, fast-acting sprays and tablets can be used as sedatives for dogs. Tablets that can be used as feed supplement contain a special mixture of vitamins and amino acids that help to relax the dog within a few hours. Sprays are also effective, but you should not spray them as a sedative on your dog but instead on its surroundings. This way, restlessness, trembling and anxiety during long car journeys or transport in a box can be reduced. These preparations also contain pheromones that are effective for up to five hours.
