For sports activities with a dog e.g. cycling, jogging etc. a harness is also recommended, as unexpected movements can always occur during such activities. The same can be said for the use of tracking leashes or retractable leashes. These should always be used in combination with a harness to avoid injuries to the cervical vertebrae caused by tugs.

After measuring the chest circumference, the harness should be fitted taking the following points into consideration:

♦ shoulders and front legs should be able to move freely
♦ the belly strap sits on the costal arch (leave at least 2-3 fingers' width between armpit and belly strap, more for large sizes)
♦ the chest strap sits on the breast bone
