Nupro is not something you will see an immediate effect with. You need to use it for about 3 months to see visible effects, and you will really notice it when your dogs drop coat and the amount of undercoat that you will see will astound you.
The product works from the inside out, making it easier for your dog to utilize whatever food you are using, and using all of the food for what they really need it for.
It makes a great gravy, and works really well for puppies new to food,and it keeps all my girls eating when they have jsut whelped. I have used it,and sold it for about 8 years now and would NEVER be without it..
