Hi I live in Northern Ontario Canada . The horses have just started shedding and are still pretty shaggy. There is still lots of snow everywhere. Would it be too late to start feeding paprika to help darken their summer coat? I have a black and white appaloosa that fades to a light brown in places and I would like to use something to darken his coat without keeping him in or covered all summer. Also would Paprika benefit a sorrel horse at all or is there something else that would make his red coat redder?
