Swaddling, or applying gentle, maintained pressure is well-known as an effective way to calm babies. Fur babies are no different. Like humans, pets have pressure points that, when activated, help calm even the most anxious dogs. Zen Dog compression shirts are made of a lightweight, breathable fabric with four-way stretch to provide just the right amount of pressure. They adjust for a custom fit and act as a cooling garment when wet. Zen Dog compression shirts are ideal for any situation your dog finds stressful, including separation anxiety, nervousness, travel anxiety and car sickness.
