If it is your habit to walk your dog on a leash, the harness is a valid
alternative to the collar. The harness is particularly comfortable for jogging, for use with training or retractable leashes,
and in case your dog has health problems (e.g. respiratory problems).
After measuring the chest circumference, the harness must be adjusted taking into account the following rules:
the dog must be able to move its shoulders and front legs freely
the abdominal strap must be positioned on the true ribs of the rib cage (measure a space of 2–3 fingers between the armpit and the abdominal strap, more for larger sizes)
the chest strap must be positioned along the sternum
