Review (4/5): Works great  (more like a medium size brush)
Brush works great. The only reason that I did not give it 5 stars is that it is smaller than I would call a "large" brush. My dog is 75lb lab/golden retriever mix. The brush works fine, but I would have preferred if it were a bit larger. I would consider this a medium brush, but again it does the job. I liked that this did not have any moving pieces that could break. These brushes clean super easy by just bending the bristles from the top down once it gets full of hair.
