Loud noises such as fireworks and thunderstorms can cause your dog a lot of stress and we know that during these stressful situations, the only thing you want to do for your pet is to make him/her feel more calm. The key idea behind the Comfort Zone Calming Vest, is our Complete Comfort Compression technology. Each vest has a full chest fit for maximum torso coverage for constant, swaddling-like pressure to help your dog feel calmer. The use of gentle pressure to cradle and calm is an age-old practice and studies with both animals and humans have shown use of pressure to be effective in reducing stress. br/>Sold in Quantity of:1
