Makes Walking Fun! The 1" wide no-pull harness features a patented control loop on the back of the harness, which tightens gently around your dog’s chest to discourage pulling and makes walking your dog an easy, more enjoyable experience. Fits Great! To measure for the harness, use a soft measuring tape (or a piece of string) and measure all the way around the LARGEST part of your dog’s chest (right behind the front legs). Choose the SMALLEST size that fits within that measurement. So, for example, if your dog has a 28" chest, we recommend the size Medium for the best fit. if the measurement is 24 inches, we recommend the Small, rather than the Medium. Keeps your dog safe! The harness is made with stainless steel hardware and four adjustment points to ensure that it is more than strong enough to hold any size dog, from 14 lbs all the way up to 250+ lbs. The chest strap is lined with Swiss Velvet, which helps prevent rubbing and chaffing sores behind the legs and the straps are all turned out to prevent sores and raw spots along the seams. Dual Connection makes it easy to walk your dog! This harness also features a structural ring on the front of the harness. Connecting to this ring is Optional but it does allow you to connect to the front and back of the harness simultaneously. The main connection on the back of the harness tightens gently around the chest to discourage pulling behavior, while the connection on the front of the harness allows you to redirect your dog’s attention back to you for training and treats. 2 Hounds Design is the exclusive manufacturer of the Freedom Harness.
