The belt harness is very stable and very well made. The tapes are very stiff. I just hope that that are even softer with use. Choosing the right size was difficult. My Dog Has 70 cm chest circumference and 25 kg in weight. So my dog lies exactly between size 0 and 1. I have chosen for size 1, because of the weight, but the dishes seemed a bit too big. I leave it to me, the smaller size does not seem safe at the weight. My dog found the dishes not so good, yet to be convinced. On me the dishes but makes a very robust impression.
