The problem
Fireworks night arrives and your dog pants, paces, and hides under the bed. Sedatives feel drastic for occasional stress, and 'just ignore it' advice rarely calms a trembling dog. If your dog's anxiety is constant or escalating, a wrap alone will not be enough — see a behaviourist.
What tends to help
The jacket applies steady, even torso pressure — the same principle behind swaddling infants or weighted blankets. Velcro panels let you adjust snugness in seconds. Roughly half of dogs show noticeable calming; the rest seem indifferent, so treat it as a trial, not a guarantee.
A straight answer: Sizing matters more than most owners expect — a loose wrap does almost nothing.
