I used this on both my dogs. One has wiry but thin fur. And the other has full on thick fur to the point where you can brush her all day and still be getting fur off her. This worked better on the furry one, but I still had to use a ton of it to be able to massage it all the way through her fur. The wiry one, this stuff would not spread and left her still stinking so I had to use my shampoo and conditioner after this. Half the bottle in one wash and it didn't even clean one of my pups, not worth it. It wasn't very expensive. But it's the principle!
