A breath of fresh air in the world of dog harnesses, the EzyDog Chest Plate Dog Harness places emphasis on the dog's comfort as well as the owner's convenience.__When pulled, the chest plate distributes the force across the dog's chest rather than the throat (as with most leads or harnesses), making for more comfortable and less abrupt usage.__This ergonomic, comfortable fit is the product of the EVA chest support moulds, which shape themselves to the dog's canine contours and never rub or pull uncomfortably.__The shape of the chest plate has been rigorously tested on different shapes and sizes (or breeds at least!) of dog, to ensure that there is always the perfect choice.__Great for training, and easy to fit and adjust with the one-click snap clips, it's a particularly hard working and innovative design._Reflective Stitching for night time safetyRust-proof welded D-Ring keeps your dog attached to the lead__Size GuideFor best fit measure the girth of the dog. This is the area behind the front legs and around the body. The neck will typically fall into place once girth is determined. If the measurement is close to the end of the size range, go up to the larger size.SizeWeightNeckGirthXXS2 - 3kg23 - 37cm24 - 38cmXS3 - 5kg27 - 46cm29 - 48cmS5 - 10kg34 - 56cm37 - 60cmM10 - 19kg41 - 68cm45 - 73cmL19 - 35kg46 - 78cm49 - 84cmXL35 - 40kg52 - 90cm56 - 97cm2XL40kg+74 - 131cm77 - 134cm
