I own a Rottweiler who sheds like crazy! This stuff works amazing and smells soooo good I opted and bought the gallon after using this. This shampoo really does get a lot of hair off. It doesn't stop your dog from shedding that's impossible but it helps with the shedding. I use the shampoo and the conditioner of this brand (The conditioner helps soooooo much) and after he's dry I use the Furminator brush and barely gave any hair for a solid week. The entire process is time consuming but well worth it if you can't stand the hair and he smells soooooo good after! The shampoo smells like a Pina Colada to me. So good! Would definitely recommend for you guys out there with heavy shedding fur babies!
