Bought the dishes for our smooth collie puppies. It weighs 12kg and is currently a slender guy. By setting one can use it any longer safe. It does not chafe and he feels not disturbed. Disadvantages: It scrubs down by very quickly. There are already some threads loosely by his Crawlers & Kriechaktionen below what animated brushing him when it rumzubeißen what the dishes not as well put away. Above are two eyelets einzuharken to the leash. These I use when running with the towline and while driving. During normal walking I use a conventional collar because the dog is therefore better control and he has to learn that yet. Here, unfortunately, the two eyelets ringing like Christmas bells, so you can hear the sound of where the dog is. But it is intended for the dog not nice when getting a running after him with a bell. Shipping as always top.
