That part is super visible to the dog in the water. For smaller dogs somewhat difficult to grasp (our 10-kg-dwarf is not able to take part at the side and must be so but very struggle ... for our 20-kg-dog is after a little practice, no longer a problem) , Also note that the dummy is not exactly a lightweight. Visually, I find him very chaotic ;-) But it swims like a buoy on the water and this is the meaning and purpose ... the dog ists matter how the part looks.
