About This

SERVICE DOG VEST HARNESS FOR WORKING DOGS — This service animal vest is built for dogs providing mobility, medical alert, and psychiatric support, with high-contrast SERVICE DOG patches for clear identification and reliable handler control. Adjustable fit for small to large breeds, XXS to XL.
MEASURE BEFORE YOU ORDER — Fit is by chest girth, not breed or weight. Measure the widest point just behind the front legs and match the size chart: XXS 15-18”, XS 16.5-20.5”, S 20-27”, M 24-30”, L 27-36”, XL 33-44.5”. Between two sizes? Choose the larger. This one step is the difference between a working fit and a return.
CONTROL & LOW-LIGHT VISIBILITY — A reinforced, padded top handle gives close control in crowded or high-traffic spaces, a metal D-ring anchors the leash, and reflective trim keeps your dog seen at night. The broad, padded chest panel helps distribute pressure across the chest for a more comfortable fit.
BREATHABLE & BUILT TO LAST — Reinforced nylon with breathable mesh padding stays comfortable through long shifts and holds up to daily working use without stiffness or bulk, while strong buckle hardware stays secure under load. Hand-wash cold and air dry; remove patches first.
2 REMOVABLE PATCHES INCLUDED — Two SERVICE DOG patches attach with hook-and-loop panels for quick swaps to IN TRAINING, THERAPY DOG, or DO NOT PET (sold separately) as roles change. For identification and handler control only — no vest certifies a dog or grants legal access rights. Trusted working-dog gear since 2016.
