Taking thorough measurements of your dog is essential for choosing the correct harness size. Place 4 fingers behind the front legs to find where to measure the chest (girth) for harness sizes 0, 1, 2, 3 and 4, and 2 fingers to take measurements for sizes Baby1 and Baby2.


Before putting on the harness, it is very important to adjust the chest strap and the lower strap under the chest correctly. If the straps are too loose, the dog might be able to back out of the harness. When the lower strap under the chest is too tight, it is uncomfortable for the dog.


Choosing the wrong harness size, as well as incorrect harness adjustment and collar use may result in the dog slipping out of the harness or the collar. If the harness is too small, the chest strap puts pressure on the dog's neck instead of distributing it over the chest area. Choosing the wrong harness size may result in injury. The right harness size should leave the dog with enough room in the shoulder area and it should be able to move its legs freely. If the harness is too big, the dog might step over the chest strap with its front legs. My Fab Dog and JULIUS-K9® holds no responsibility for any injuries resulting from choosing the wrong harness size or incorrect harness adjustment.
