Demigreat Service Dog Harness – Reflective No-Pull Vest with 5 Patches, Adjustable Oxford Nylon, Medium, Purple

The Demigreat Service Dog Harness is a no-pull vest designed to give you better control during walks or training. It features three metal D-rings (two on the chest and one on the back), reflective tape for low-light visibility, and comes with five embroidered patches (2 service dog, 2 in training, 1 paw). The outer shell is reinforced Oxford nylon, while the inner layer is a breathable mesh for comfort. This Medium-sized purple harness is adjustable at the chest and neck, so you can fit it without slipping it over your dog's head.

What makes the three D-ring system useful?

The Demigreat harness has three attachment points. A front D-ring on the chest helps discourage pulling—when your dog pulls, the harness gently turns them sideways. The back D-ring (on the top) is for relaxed walks or jogs where you want a straight line. A third ring on the chest provides another option for clipping a leash. All rings are reinforced with strong webbing to handle tension evenly, reducing strain on your dog’s neck compared to a collar.

How to choose the right size for your dog

This Medium size is intended for dogs with a chest girth around 22–28 inches and neck 16–22 inches (exact measurements vary by dog). To get the best fit, measure around the widest part of your dog’s chest and around the base of the neck. Then compare those numbers to the manufacturer’s size chart. Don’t rely solely on weight; the harness is adjustable to fine-tune the fit. If your dog is between sizes, choose the larger one and tighten the straps.

A closer look at the materials and build

The outer shell is made of reinforced Oxford nylon—a tight-weave polyester that resists abrasion. The stitching uses what the manufacturer calls reinforced knitting technology, which adds durability. Inside, the mesh layer sits against your dog’s skin, allowing air to circulate and heat to escape, which is helpful on warm days or during active walks. The buckles are heavy-duty plastic with a snap closure, and the adjustment slides are metal for secure positioning. The reflective strips are sewn onto the sides and front of the vest; they bounce back car headlights or streetlights, making your dog more visible from a distance in low light.

What patches are included?

The harness comes with five patches: two that read “SERVICE DOG”, two that read “IN TRAINING”, and one paw-print patch. They attach via hook-and-loop (Velcro) panels located on each side of the vest. You can mix and match or remove them entirely. The patches are embroidered with a bold white font on a black background, so they’re easy to read.

Frequently asked questions

Can I use the back D-ring for training?

Yes, but it’s better suited for loose-leash walking or jogging. If your dog tends to pull, the front D-ring gives you more leverage for no-pull training.

Is this harness safe for a dog that pulls hard?

The reinforced Oxford nylon and double-layer stitching are designed to handle moderate pulling. For extreme pullers, check the straps regularly for wear. The harness is meant to reduce pulling, not restrain a dog aggressively.

Will the patches stay on during active play?

The hook-and-loop backing is fairly strong. However, if your dog rolls around in dirt or brushes against bushes, patches can come loose. They are easy to reattach.

How do I clean the harness?

The manufacturer does not specify a cleaning method, but the materials (nylon and mesh) can usually be hand-washed with mild soap and air-dried. Remove the patches before washing to protect the embroidery.
