Thundershirt ThunderShirt for Dogs Calming Anxiety Vest — Small Heather Gray, Adjustable Pressure Wrap

The ThunderShirt for Dogs Calming Anxiety Vest is a soft, adjustable pressure wrap that helps reduce stress-related behaviors in small dogs.

Designed to apply continuous, gentle pressure across the torso, this original ThunderShirt model aims to make noisy or unfamiliar situations easier for anxious dogs. Made in a breathable heather gray fabric, the Small size fits dogs with smaller frames and is machine washable for simple care. Many pet owners report noticeable behavioral improvements when using ThunderShirt alongside other calming strategies.

How does the ThunderShirt work to ease my dog's anxiety?

The vest uses patented calming pressure technology: snug, steady contact around the body that mimics a reassuring hug. That pressure can help some dogs feel more grounded in stressful moments without medication. It’s simple to put on and adjustable so you can find the right level of snugness for your pet.

• Patented wrap design distributes gentle pressure across chest and torso.
• Adjustable fasteners allow customized fit for comfort and effectiveness.
• Works immediately in many dogs; no training required to use.

Will this Small size fit my dog and how do I measure?

Measure around the widest part of your dog’s rib cage to choose the correct Small size; a proper fit is snug but not restrictive. The vest fastens around the neck and belly, and the adjustable straps provide a secure hold so it won’t slip during movement. If in doubt, compare your dog’s measurements to the manufacturer sizing chart before ordering.

• Measure girth at the ribcage for accurate size selection.
• Fastens at neck and belly for a stable, custom fit.
• Lightweight fabric accommodates full range of motion.

In what situations could I expect the ThunderShirt to help?

ThunderShirt is commonly used for acute stressors like storms, fireworks, vet trips, grooming, travel and separation. It aims to reduce stress-driven reactions such as excessive barking, pacing, hiding, or destructive behavior during those events. For best results pair with soothing routines and, if appropriate, consult your vet for a comprehensive plan.

• Useful during thunderstorms, fireworks, travel, and vet visits.
• Supports calmer behavior in rescue dogs and newly adopted pets.
• Compatible with additional calming products like pheromone sprays or treats.

How do I care for and maintain the vest?

Because it’s designed for regular wear, routine washing helps maintain hygiene without compromising the wrap’s performance.

• Machine washable on gentle cycle; air dry to preserve shape.
• Soft, breathable fabric prevents overheating during use.
• Durable construction for repeated wearing and washing.
