The dog’s chest measurement should be taken at the widest point of the chest, from behind the front legs. The chest strap of the harness will settle at about 5 cm/2″ behind the point of the chest measurement. This is why the chest measurement taken from the position of the strap may be less than the measurement taken from the widest point of the dog’s chest. Depending on the shape of your dog’s chest, it may be possible to choose a smaller size of the updated harness model.
