I have a tea cup Chihuahua and a Black Lab. Both of which shed LIKE CRAZY! My “ChiChi” (The Chihuahua) loves being groomed. She is the princess of the house and loves this brush. My favorite part is it’s adjustable for using her small frame. The lab would use the larger part of the shedding brush. Essentially the two sided stainless steel blade is my favorite aspect of this brush. Before, I had to purchase two brushes to please both dogs and now I only need one! My results with weekly use has decreased shedding drastically. Love my new favorite brush.
