With long haired dogs I would not be without this product in their 'medicine chest'. The first sign of loose stools I add a teaspoon full for a couple of days and we have solid stools again in no time. It works by absorbing the liquid in the stools so is natural and safe to use. It must taste nice too as the dogs lick every last bit from their bowls. It can certainly save trips to the vet as it stops a minor problem getting worse.
