Size chart
Measure the widest part of the chest just behind the front legs. XS: 13 to 17 in (33 to 43 cm). S: 16 to 21 in (41 to 53 cm). M: 20 to 26 in (51 to 66 cm). L: 24 to 33 in (61 to 84 cm). XL: 30 to 40 in (76 to 102 cm). Between sizes, choose the larger one.
Materials
Harness: 600D nylon webbing and shell, polyester air mesh lining, EVA foam padding, POM quick-release buckles, zinc alloy D-rings with matte black finish, reflective polyester piping. Leash: 600D nylon webbing, neoprene-padded handle, zinc alloy swivel snap hook.
Safety
Supervise your dog while wearing the harness. Check buckles, stitching and rings before each walk and stop using the set if any part is damaged. Not a car restraint; not for tie-out, towing or lifting a dog by the handle for more than a moment. Keep away from puppies as a chew toy.
Will the front clip stop my dog from pulling?
It changes what a pull does: instead of dragging you forward, it turns the dog toward you. The habit changes with practice, so give it a few outings; patient training does the rest.
Which size should I order?
Measure the widest part of the chest just behind the front legs and use the chart on image 5. Between sizes, choose the larger one; the four adjusters take up the slack.
Can my dog wear it in the car?
No. It is not a crash-tested car restraint. For rides use a crash-tested car harness or a crate, and clip Trail Set on when you arrive.
How do I wash it?
Close the buckles, machine wash on cold in a laundry bag, air dry. No bleach, no dryer.
Why a Y-shaped front?
A strap straight across the chest sits over the shoulder joints and shortens the stride. The Y sits on the breastbone, so the front legs swing freely.
Which size for a growing puppy?
Measure today, choose the size whose range your dog is in now, and set the adjusters loose; the Puppy Set covers the first months, then Trail Set in whatever size the chart says.
