We have a miniature Australian Shepherd named Bentley. He sheds like crazy. Well he did ! I purchased a few small sized shampoo bottles just to try it out. I was hooked on the first one . The smell is awesome and it last a long time. If he dosen't spend a lot of time outside you can still smell the shampoo scent almost two weeks out. I had an issue with a gallon of shampoo I bought off of Amazon. It came with no scent and no pump dispenser. I call Pride and Groom and they sent me another one with scent in it and a pump immediately. We live out in the country with lots of acreage. Last night 10/30/22 we were sitting out side off of our patio listening to music and Bentley shot out into the dark night as I am hollering for him to come back. He came right back but with skunk spray on him. I immediately put him in out patio sink and started washing him with pride and groom. I washed and rinsed him twice and it got out about 97% of the smell ! I was very impressed!
