I cannot recommend this harness enough. I have a very big strong dog who pulls and lunges a lot. It had gotten to a point where walking him was becoming increasingly difficult and dangerous. This harness was recommended by my dog trainer and it has made such a huge difference. The harness is extremely well made with wide comfortable straps.. the design makes it easy to put on especially for dogs who don’t like things being passed over their heads. The two rings made it perfect for use with a double ended lead . Because it comes in 3 separate sections it means you can adjust to the perfect size needed for your individual dog. I found the service I received absolutely top notch from start to finish. Steph was fantastic in advising me right from the start after I sent measurements and pictures to ensure I had the right fit. Once the harness arrived I sent more photos in and Steph suggested I change one of the pieces to allow room for growth, this was sent straight away to exchange. Fantastic company, great products and excellent service.
