After brushing Penny -- a Cavalier King Charles Spaniel -- with her regular brush, I ran the FureverBrush down her back, and it picked up enough hair to stuff a king sized pillow.
The brush snags on Penny's fur, and I have to pull it through. I brush her daily, and the new brush pulls out gobs of hair with each stroke. But her coat looks even more luxurious than it did before. She doesn't object to the snags.
Note: Penny grew a second coat in this chicago winter's cold temps, so maybe she's shedding twice as much as usual. But hew new brush does a great job.
