ThunderShirt Classic Dog Anxiety Relief Vest Large

Overview

ThunderShirt's Large classic vest applies gentle, constant pressure intended to calm dogs during stressful triggers like thunderstorms, fireworks, or travel. This heather gray version is sized for dogs with a 25 inch neck and 30 inch chest, and closes with a classic wrap design.

The idea behind ThunderShirt is swaddling pressure rather than medication, so it works differently from calming chews or pheromone diffusers. Fit depends on measuring your dog's neck and chest against the size chart rather than just weight, since the Large size lists a 40 pound minimum but the neck and chest numbers matter more for a snug fit.

• Large size: 25in neck, 30in chest
• Minimum weight 40 lbs
• Heather gray, classic round neck
• Machine washable fabric

Who it's for

Dogs that show anxiety around loud noises, car rides, vet visits, or separation, where owners want a non-medication option to try first. Not a fit for dogs whose anxiety stems from pain or a medical issue that needs veterinary treatment.

Pros and cons

Performance notes

The vest closes around the torso in a wrap style meant to apply steady pressure, similar in concept to swaddling. It is made from a breathable soft fabric and is machine washable, so it can be reused across multiple stressful events without needing replacement.
