This is by far the best milk substitute for puppies that I have used . Used it for the first time last year on a litter of 9 and the pups loved it the weight gain was brilliant. The product mixed easily and comes out a lot thicker than the ones I have tried before . Looks and smells nicer there was no problem with loose stools or constipation which I have had in the past . Well pleased with the product and the results. Quality.
