Yesterday we received the delivery (thanks to Amazon, prompt delivery, as always without any problems) and now I've tested it. Result: dog hair very well brushed and sucked without tangles. There are no loose hair flying around more, everything is caught. I am very pleased! We have a long-haired white stock Schäfer, ie partially longer coat, sometimes shorter on the legs. Coat length absolutely irrelevant, everything will be fine brushed out. Of course, the dog must be already accustomed to the vacuum cleaner, but this was never a problem with us. A top product of Dyson, really kanns only recommend!
