FAQs
Y-front vs vest harness?
Y-front: most natural movement, ideal for active dogs. Vest: more chest coverage, warmth, support. Both work — pick by your dog's needs + temperament.
Step-in style?
Easier put-on/off (especially for nervous dogs). Less front coverage. Good for small + medium breeds. Adjustable for ideal fit.
