I have a Havana and a Maltese so small dogs have a lot of hair. B-55 worked well. Turned it on in another room and both dogs got used to the sound in the same bathroom. It took about half the time to dry the coats compared to the hand dryer. I can blow and brush wool at the same time. Reliable dryer for my dogs. The vacuum cleaner function is cool, but I haven't used it yet.
