Pressure wraps including Thundershirts are widely used for dog anxiety with some evidence of benefit, representing an accessible welfare tool when used appropriately as part of a comprehensive anxiety management approach.
Pressure wrap welfare contribution is modest but real for the subset of anxious dogs who respond positively. Animals experiencing anxiety benefit from any evidence-supported intervention that reduces distress, and pressure wraps provide accessible, non-pharmacological reduction in anxiety intensity for many dogs. The critical welfare context is that pressure wraps address symptom intensity rather than underlying anxiety - dogs wearing wraps during thunderstorms are experiencing less intense anxiety, not being treated for the anxiety disorder. For mild anxiety, wraps may provide adequate management; for moderate-severe anxiety, they should be components of a comprehensive treatment plan that includes behavioral modification and appropriate medication.
