Fantastic! I wish I would have found this product two years ago! I have cattle dog mix rescues. My female, Tiwi, stresses so badly on leash, she completely flips out. I tried four or five different "no-pull" products, watched countless videos, enrolled her in classes to no avail. I felt bad leaving her behind while I took her brother, Taz, on fabulous walks and hikes. The Luxurious Comfort Dog Harness arrived two days ago. Since then, I've taken both dogs on long walks, including an extended hike. Tiwi didn't pull a bit. She's like a completely different dog on leash with the harness! The product fits so perfectly, thanks to the measurement recommendations. I'm not overstating it when I say this product is life-changing for Tiwi and me! Thank you!
