Purple strap harness with adjustable fit and front D-ring for small dogs

FlexStrap Harness

$26.99
$26.99

The FlexStrap is a minimal, strap-style harness built for lightweight wear and easy movement. Its simple, airy design covers less than a vest-style harness, which suits very small dogs that do better in a lighter, less bulky build. Multiple adjustment points let you fine-tune the fit on a tiny frame, and the D-ring gives a secure leash attachment. Available in sizes S and M for small and toy breeds.

The FlexStrap comes in sizes S and M, built for small and toy breeds. Always measure your dog before ordering rather than choosing by weight alone, since chest girth is the most reliable guide to a proper fit.

Size Weight Chest Neck
S Under 3 kg
(under 6 lbs)		 25–38 cm
(10–15 in)		 19–38 cm
(7–15 in)
M See note below* 36–50 cm
(14–20 in)		 38–58 cm
(15–23 in)

*For size M, chest and neck measurements are the most reliable guide, since weight can vary more between individual dogs at this size.

To measure, wrap a soft tape around the widest part of the rib cage, just behind the front legs, for the chest girth, and around the base of the neck for the neck measurement. For fluffy or long coats, measure under the coat, not over it. The harness should sit snug with two fingers fitting underneath comfortably.

Light Enough That Your Dog Forgets It's There

Some tiny dogs feel weighed down by a full vest harness. The FlexStrap takes the opposite approach: a minimal, airy strap design that covers less and lets your dog move freely. The lightweight build sits comfortably on the smallest frames without the bulk that overwhelms a toy breed, and the multiple adjustment points let you dial in a precise fit as your dog grows or between sizes. It's a natural choice for Chihuahuas, Yorkies, and Maltese who do better in something light and flexible rather than padded and structured. If your small dog dislikes heavy harnesses or simply moves better with less coverage, the FlexStrap gives freedom and a fully adjustable fit in one simple design.

F.A.Q

Yes, the FlexStrap has multiple adjustment points so you can fine-tune the fit as your dog grows or if they fall between sizes. This makes it a practical choice for puppies and tiny dogs whose measurements change over time.

The FlexStrap is built for lightweight comfort, not pull control. For dogs that pull hard, a structured no-pull design suits better. The FlexStrap is ideal for calm tiny dogs who move better with a light, low-bulk harness and don't need heavy structure.

The straps are designed to sit flat and distribute light pressure across the body. Because the FlexStrap is meant for small, light dogs, the gentle tension stays comfortable. Adjust each strap so two fingers fit underneath, and check that nothing twists, for a smooth, rub-free fit.

The FlexStrap comes in sizes S and M, fitting a chest girth from 25 to 50 cm (10 to 20 in). Size S suits dogs under 3 kg (6 lbs). Because the strap design is highly adjustable, measure your dog's chest and check the Fit and Sizing menu above to find the right size.

If you already have a leash you like, or you're buying the FlexStrap as a second harness, the without-leash option saves you a few dollars. Otherwise, the with-leash version gives you everything you need in one order.

The FlexStrap is built for very small and toy breeds needing a light, adjustable fit. The GlideStrap is designed for long-bodied dogs like Dachshunds, with an open-frame shape that follows a longer body line. Pick based on your dog's body type rather than size alone.

Rinse by hand in cool water with a mild soap and air dry. Avoid bleach, machine washing, and tumble drying to keep the straps and adjustment points in good condition over time.
