Meaning that each spring carries half the weight of the backside of the dog. Adjust the tension on the Spring Adjuster until there is sufficient tension to support your pet when standing and also when moving from sitting or lying down position to standing position. The tension should also not be too much so that your pet will need little effort to move from standing position to lying down or sitting position. This will take some effort to achieve because it will need a bit of trial and error until you find the perfect tension balance for your pet.
