Hi! The Mango Tango is a both a shampoo and conditioner (2 in 1), while the Oatmeal & Aloe is only a shampoo. For stronger fragrance, the Mango one the smell will last longer, but the Oatmeal & Aloe shampoo also smells great (Vanilla scent!) and the oatmeal formula will help your pet have healthy skin and softer fur. Hope that helps!
