It was spring again and again set off the extreme Dog Haarerei. As a convinced owner of Dyson vacuum cleaners for over 10 years, I thought that this dog brush would be a fantastic addition to the cleaning system. So far I had always resorted to the seasonal Haarungs times my dogs on an emergency basis to the basic accessory brush, the little round thing that accompanies virtually every Dyson. Yes, I know it is here that the Groom brush is intended for long-haired dogs. I have read various recessions and beschieben, let me by some that this bust as "absolutely great" and "also for short-haired dogs suitable" tempted to order these brush. As I said, my dogs know it to be drawn off and come voluntarily, if I put the brush on the vacuum cleaner bisherig related. When I now this new brush for the first time used, I harvested only "autsch'n" and indignant glances of my two dogs, along the lines of "what are you doing ??" No matter how I used the brush (standing in a review, it would be no problem at Shorthair dogs the bristles just a little push out), it did hurt my dogs again and again! I have a Bordeaux mastiff and a German shepherd, so short and semi-short hair. And- all honesty even if I had long-haired dogs, those sharp metal prongs I would NOT recommend dog owners! It's like a wire brush hook of the first generation, something has been recommended for dogs Brushes 40 years ago! Even with long-haired models you scratch it (by the hook shape and unprotected tips) inevitably the skin on! I do not understand how these days at all can sell anything! The basic idea and the mechanical concepts are really great! If you only thin and sharp wire bristles against two different models would now exchange (for long and short hair) with rounded plastic bristles, many dog owners would certainly be very satisfied! What use to me a super combed dogs with whom I then subsequently run to the vet because he has skin infections caused by torn skin and continually scratch because of scab ??? Again conclusion: absolutely unsuitable, particularly for short-haired DOGS !!!
